Supported Radios

Go look here for Radio Computer interfacing

Note. Not all the features listed in this Help/manual might be applicable to all the transceivers and brands mentioned below. Known settings for transceivers or features not applicable are mentioned below as far as we know them. Please inform us if you have information which should/could be mentioned here.

General information

When using a home-brew self-powered interface set the handshaking to:
- DTR - Always On
- RTS - Always On
- Like when using ICOM clone cables
All radios: Band change is not allowed while transmitting
All radios: Timeout for all radios is default set to 10 seconds (user settable).
- Some radios require initialization commands for configuration. These are sent to the radio when the program starts. Users should have the radio and interface powered prior to starting the program so this can occur. If the radio needs to be power cycled after the program has initialized, right click in the Bandmap and select Reset Radio to perform this initialization again
- A warning message will be displayed when no response received from the radio and the radio will be changed to a manual radio by the program.
- To get the radio working again select in the right-click menu from the bandmap "Reset radios"
- When the radio control gives a warning 10 seconds after you start the logger, then you never had radio control at all, and you should check your hardware, and serial port settings. Consult the manual from your radio and also read below.Some radios require initialization commands for configuration. These are sent to the radio when the program starts.

Polling of radios while sending CW is supported for all radio except for FT-1000.
It may appear that the Up Arrow, Down Arrow, Page Up or Page Down are not working when incrementing or decrementing the current frequency with these keys.
- The VFO frequency will not change if the incremented/decremented amount is smaller than the frequency deltas supported by your rig. This is not always well documented by the manufacturer. Icom 751 rigs for example do support 10 Hz steps but only show 100 Hz steps on the display.
- The keys mentioned above have to be set higher than the minimum step size supported by the radio.
- It's easy to test if it is the keys are working. Check the frequency while pressing the keys mentioned above. If the frequency moves nothing has to be changed.
- The default increment/decrement for CW is 10 Hz. If this doesn't work, try changing it to 100 Hz, under the Configurer, Other tab.
- This only applies to the keys that increment/decrement the current frequency.
Kenwood, Orion, Icom, FT-1000MP - Code has been added that requires new band changes to be received twice from the radio before changing band. This change is to improve the reliability of frequencies displayed/used.

NB: This will make band changes made from the radio twice as slow to appear as band changes made from the program.

Memory mode - most modern radios (100mp, TS2000) have a kind of memory mode. In this mode the radio will normally not function with the program. Use VFO mode instead.
When SO1V mode is selected, VFOB is not defined for receiving. The user should close the second Bandmap and Entry window.

Manual mode

In manual mode no radio is selected and attached to the program. If possible always connect a radio using the CAT interface or serial port. Older radios (or very new not supported radios) can still be used with the program by selecting Manual but many functions in the program will not work as easy as they could or will not work at all. When a radio is not configured, it is the user's responsibility to make sure the mode and band are correct when logging contacts. When no radios are selected in Configurer, the program will attempt to set the initial operating mode and frequency in single mode contests when the program starts or a new contest is opened. The program uses information from the contest selection and the mode tab settings in Configurer.

Elecraft

Elecraft USB-serial converter issues and N1MM logger

Situation: Setting up Elecraft K3 to work with N1MM logger and simply key CW with DTR line of CAT port.
Results: CAT works fine, but every time I try to send CW there appears an error window "CommPortDev_OnComm 4 - 2147417856"

N1MM is totally blocked and has to be killed using task manager.

Solution: The Elecraft USB-serial converter uses a Profilic chip, and the (Win2K) Profilic driver doesn't work correct for CAT and DTR-CW-keying using the same port.

A USB-serial converter using a FTDI-chip and the FTDI drive is working fine, CAT ok, fast CW keying, ESC immediatly interrupts message ...

All ufb now :- Tnx Thomas DK3DUA

K2
- Uses Kenwood alike commands but has it's own radio selection. Only the KY command which is Elecraft specific is not supported.
- Use default Kenwood parameters but sometimes one (1) stopbit only works (contrary to the K2 KPA100 manual saying that 2 stop bits should also work).
- N1MM Logger does not support the K2 "virtual keying" feature using commands sent to the K2 serial port.
- Setting the "Wide" and "Narrow" filter codes.
  - Remember to set the filter codes for both VFOs. Get the appropriate N1MM Logger screen menu prompt by left clicking when your cursor is over the active VFO window.
  - Substitute this code for the complete Kenwood "FL" code that comes up by default: K22;FW99991;K0; (no spaces, all caps, include the ";"'s) This will set the filter to "FL1" on the K2. If you put this code in the SSB "Wide" section for the filter code, it will give you FL1 for SSB - if you put this in the CW "Wide" section, it will give you FL1 for CW. Remember that the actual bandwidth of the filter will depend on how you have set FL1 on your K2. The same is true when you substitute this string for the "Narrow" settings. If you want a filter other than FL1 in either mode, just change the "1" after the 9999 to the number of the filter you want to invoke ie: 1,2,3 or 4. As an example, K22;FW99993;K0; placed in the code section for CW "Narrow" would invoke FL3 when the switch is set to "Narrow" and you are on CW.
  - Briefly, "K22" tells the K2 that this is an "extended command mode" - the ";" tells the K2 that this command is finished - the "FW" tells the K2 that this is a command to set the filter width - the 9999 number is ignored in the string but is necessary to include (it can be any set of four numbers between 0 and 9999 - I just picked 9999) - the "1" is the number of the filter to invoke (1 - 4) - the "K0" (that is "K" zero) tells the K2 to go back to the "normal command mode."
  - Use the same technique to set the RTTY filters as well. Have fun es 73, Don N4HH
- Please check out the feature which works great with the K2 and TS850 etc that don't have RIT clear IF you are Running (doesn't work for S&P). Put the rig into split, and use VFO B as your "RIT". Then go into Config, and turn on "Reset RX Freq when Running Split". Using VFO B for RIT, tune in a caller off freq, work him, and at the end of the QSO VFO B will be set to VFO A freq. Neat feature, and specifically designed for this situation.
K3

For SO2V use, the second receiver needs to be installed and enabled. A single receiver K3 can not be used in SO2V mode due to radio and/or firmware limitations. If the firmware limitation is corrected, SO2V operation will be possible with a single receiver K3.
A single receiver K3 can only be used in SO1V or SO2R modes. A dual receiver K3 can be used in all program modes.
ALT+F12 toggles Sub on and off. It is identical to pressing the SUB radio button and it ignores the diversity selection. To leave SUB on all the time, select Configurer, “Dual RX always on”.
In SO2V mode, radio split must be controlled by the program. If the user presses the radio split button, the radio and program will not be in sync. This is due to the radio's firmware defination of split when receiving and transmitting on VFOB with the second receiver installed.
Using the program as a voice keyer eith a K3 on SSB

Connect your microphone to the mic input of the sound card and the Line Out of the sound card to the Line In on the back of the K3.
Set soundcard program to drive Line In.
Select LINE IN with MENU:MIC SEL
Command Tx (or PTT or...) and adjust the MIC GAIN (which is now LINE IN gain) for proper audio level.
Connect Mic to desired mic connection.
Select MIC with MENU:MIC SEL
PTT and set Mic Gain.
"Now, if set MIC+LINE ON then both audio sources will drive the K3. The MIC GAIN control will control the MIC GAIN only. LINE IN GAIN must be set when LINE IN is the selected source via MENU:MIC SEL"

The K3 accepts CW on DTR (pin 4) of the same COM port you're using to control the K3. Set N1MM to send CW on that port (Ports setup), and set PTT-KEY (second K3 CONFIG menu) to OFF-DTR, and set the K3 for QSK.In other words, you don't need that transistor adapter unless you want to do SO2R.

N1MM does NOT work for SO2R with CW and control on the same COM port, but it does for ONE radio.

The K3 can accept PTT switching on its radio control port without any separate keying circuit and without using a second serial port. For example, if the K3's CONFIG:PTT-KEY item is set to RTS-OFF with RTS configured for Always on in the Logger, the radio will be permanently in transmit whenever the Logger is open. You need to make the settings in the Configurer for the radio control port match the
settings in the K3's CONFIG:PTT-KEY menu item, e.g. CONFIG:PTT-KEY set to RTS-OFF with RTS configured for PTT.

SDR-1000 and SDR-5000A (using Kenwood settings)

By: Rob AB7CF
Some setup details are not really needed but are included for completeness. One thing I notice different is in PowerSDR Cat setup I use ID as: "PowerSDR" though it shouldn't make a difference. Probably the most common Vcom mistake is a failure to click Update Driver and following the procedure after making a change in Vcom configuration..
Example: using VCom configurator using ports 4-5 defines and VAC
Check your VCom configurator to make sure you have a check box in the COM4 - COM5 pair and you have clicked Save Configuration. MAKE SURE you click the Update Driver and follow the instructions. Close VCom configurator. Click on Window's Start Button, Click on ControlPanel, Click System, Click on the Hardware Tab, Click on Device manager.
In Device manager make sure there ISN'T a yellow question mark on the entry labeled "Multi-port serial adapters." If there is no yellow question mark your Vcom virtual cable should be working properly. If there is an yellow question mark there is a problem with your Vcom installation which needs attention. Assuming no problem, Close ControlPanel.
Now check PowerSDR. Open PowerSDR Setup and click on the CAT Control tab. In CAT Control make sure Enable CAT is checked. Under PTT make sure Port 4 is selected and RTS and DTR are unchecked. Select ID as: PowerSDR. Click Apply. Close PowerSDR Setup.
Now check N1MM. Click Config. Select "Configure Ports, Telnet Address,Other" Under Com-5 select Kenwood. Make sure CW/PTT is unchecked. Now click Set. In the popup box the settings should be: Speed 4800, Parity: N DataBits: 8, Stop Bits: 1 DTR (pin 4) = Handshake. RTS (pin 7) =Handshake, 1 selected in Radio/VFO. Leave the "Radio PTT via command" check box UNCHECKED. Check the "Allow external interrupts" check box. Click Okay (twice) to back out.
Now you should be communicating with your SDR. Check that clicking a new frequency in the Panadapter changes frequency in N1MM. With the focus in N1MM check that the keyboard up and down arrows change the PowerSDR frequency.

Icom

General Icom information
- Almost every rig requires an ICOM CT-17 CI-V interface or compatible. A great list of CI-V interfaces can be found at the website from Ekki Plicht, DF4OR.
- Icom rigs use software handshaking. That means they do not use DTR and RTS. However, interfaces that get their power from the RS232 port require you to set DTR and/or RTS to "Always On" to supply power to the interface. Check your interface manual to see how DTR and RTS must be set.
- Set N1MM Logger and the rig to:
  - Address - see specific rig information below
  - Baud Rate - 9600 or 19200 (see specific rig maximum rates below)
  - Data Bits - 8 bits
  - Parity - None
  - Stop Bits - 1 bit
- On your rig, set:
  - "CI-V Transceive" to OFF - this is very important. If CI-V is set incorrectly the Bandmaps will not update as the VFO is turned. If the VFO is turned continously, the program may produce a stack overflow and halt.
  - "CI-V with 731/735" to OFF. On some rigs this is referred to "4 or 5 Byte Data" or "Frequency Data Length". You want your rig to use 5 data bytes for the frequency. A few rigs noted below do not have this option.
- Due to the limited Icom radio control, the user needs to control the radio from the keyboard. This means that the user can not press these buttons on the radio: SPLIT, DUALWATCH, CHANGE, VFO/MEMO, A=B, A<>B, or MAIN/SUB. Icom radios only report the VFO frequency of the active VFO. Because of this, the program will select each VFO to read the frequency at initialization.
  To set and clear split use ALT+F7 or one of the other keyboard commands. Split will be correctly set/cleared when clicking in the Bandmap or Available windows. To select VFOB (SO2V mode only), use the PAUSE or CTRL+Right/Left Arrow keys. In SO2V mode, the VFO is also selected with a Right or Left click on the band buttons in the Available window.
- Frequencies > 2 GHz are ignored and not sent to the radio.
- To do CW with an ICOM radio a cable is needed between the radio and the serial or parallel port with an appropriate interface.
- The ALT+F10 swap VFO frequency command is disabled during SO2R for Icom radios that lack a swap VFO CAT command. This is because the program is unaware of Icom VFO B frequency in SO2R mode.
The models below are supported:
- IC-271 / IC-471 / IC-1271
- IC-275A/E/H using address 10 hex and 9600 bps.
- IC-375 / IC-575 (all versions)
- IC-475A/E/H using address 14 hex and 9600 bps.
- IC-703 using address 68 hex and 19200 bps.
- IC-706 using address 48 hex and 19200 bps.
- IC-706MKII using address 4E hex and 19200 bps.
- IC-706MKIIG using address 58 hex and 19200 bps.
- IC-718 using address 5E hex and 19200 bps.
  - Set N1MM Logger to 19200 bps and the radio to "AT" (AuTo).
- IC-725 using address 28 hex and 9600 bps.
- IC-728 using address 38 hex and 9600 bps.
- IC-729 using address 3A hex and 9600 bps.
- IC-735 using address 04 hex and 9600 bps.
  - The CI-V command set lacks split ON/OFF commands. This prevents the program from controlling the radio split.
  - When the IC-735 is used with factory settings (1200 baud, transceive ON), the bandmap response of N1MM is extremely
    slow. Jumpers J22 located on the PL-unit board (upper side under PA unit) allow baud-rate, address and CI-V transceive to be changed. But.. the jumpers are not labeled and not in the order as stated in the Service manual. In fact transceive ON/OFF is the last one (front panel toward you, tarting from left) this one should be removed to turn transceive OFF. The 2 first ones set the baud-rate (move the second one to the first position to switch from 1200 to 9600 baud) the 3 remaining ones are the CI-V address - default 04; is with last the last one of this group of 3 - ON.
    
    Jumper J22 settings for 9600 baud, transceive OFF and default address 04 - from left to right with front panel toward you...
    
    1 2 3 4 5 6
    
    ON OFF OFF OFF ON OFF
    
    Baud rate Baud Rate Address Address Address CI-V transceive
    
    Those settings make the 735 operable with N1MM (trx IC735 / baud rate 9600 / 8 data bits / no parity / 1 stop bit)
    DTR and/or RTS are not used by the Icom CI-V (no handshake) so does not matter. However, they should be turned to "always ON" if using an interface powered though those pins. Alternatively, they can be used for CW and PTT, for example if you are limited by the number of COM-ports on your machine. 73' Patrick F6IRF

Kenwood

General Kenwood information
- All models are supported
  - Newer models connect directly via a serial port cable.
  - Older models need the Kenwood IF-10 and/or the IF-232C interface (or compatible). Please check the radio's manual.
- Hardware handshaking is mostly being used. This means that DTR= Always on or handshake and RTS = Always on or handshake.
- The stock Kenwood interfaces (IF-232 for the older -x40 and -x50 series transceivers) and a bare RS-232 cable for the more recent TS-480/570/870/2000 require handshake. Except for the TS-570. the solution is to install a jumper between CTS/RTS pins at the RS-232 input of the Kenwood interface (in the case of the -40 and -50 transceivers) or transceiver (TS-480/870/2000). The TS-570 can lock-up if RTS is connected to CTS and requires RTS=always high to be reliable.
- Using the jumper ("fake handshake") will free RTS for PTT in addition to DTR for CW. The alternative to "fake hand- shake" is to set RTS=Always On and use DTR for PTT or CW as necessary (DTR is not connected in the radio/interface).
- RX/TX information from the radio is ignored while sending is in progress to avoid glitches in sending.
- Kenwood uses by default:
  - Speed: 4800 Baud; Parity: N ;Databits: 8; Stopbits: 2 (!) and "handshaking" which means RTS and DTR should be set to "Handshake".
  - When setting split both VFOs are forced in the same mode.
The models below are supported:

Kenwood

Probably the choice to use fot all modern Kenwood radios. Other possible selections are Kenwood-Slow or TS-2000

TS-480

"PTT via radio command" is not supported when using "AFSK" via the data jack. TS-480 owners have two options:
Use hardware PTT (RTS) from the digital port connected to pin 3 (DTR) of the DATA port for digital PTT. Configure MMTTY and/or MMVARI interfaces to activate DTR for PTT.
Use the microphone input for AFSK/PSK. This will allow the use of "PTT via radio command".

TS-570
- Select: Kenwood
- When using the ACC2 port on the back, you must send both the audio signal and the PTT signal to the ACC jack.
- You can't use the normal PTT connection from the MIC jack if you are inputting audio into the ACC jack.
- SO2V: 9600,N,8,1,handshake,handshake,radio/VFO=1
TS-950sdx

Select: Kenwood
Some (older) TS-950sdx radios drops power when it's polled by a logging program. It's pretty obvious on either CW or SSB.

The problem is not the program but the ROM firmware chip. The big one one the digital board of the 950sdx.

Just replace the chip, the problem should go away. Costs about $27.00 - and very easy to install (about 10 minutes)

Order a battery if you haven't replaced it already - it's right next to the chip on the same board....
Speed: 4800 Baud; Parity: N ;Databits: 8; Stopbits: 2 (!)
Check out the possible communications issue above with this radio.

TS-850

Select: Kenwood
Turn off AI on init
Speed: 4800 Baud; Parity: N ;Databits: 8; Stopbits: 2 (!)
Check out the possible communications issue above with this radio.

Kenwood-Slow

A work around older Kenwood EPROM issues for the followwing radios. Please do not select Kenwood but Kenwood-Slow.

TS-50
TS-140
TS-440
TS-680
TS-711
TS-790
TS-811
TS-940

TS-2000

Select: TS-2000 - There is a separate radio entry for TS-2000 to allow control of antenna RX input.

Uses default 9600 Baud; Parity: N ;Databits: 8; and 1 stopbits. DTR= Handshake and RTS = Handshake
When using 4800 baud, 2 stopbits must be used!
With menu item 56 the speed can be changed.
Also works for frequencies above 100 MHz
Do not use the radio function called "auto-mode". This function automatically changes the radio mode.

This overrules the (fixed) radio mode set by N1MM logger under the mode tab in Configurer.
NB.This could give AFSK RTTY (LSB) problems when changing between the higher (USB) and lower (LSB) bands.

Do not use the radio in memory mode, use VFO mode. The program will not function when in memory mode with the program.

N1MM logger looses communication with the radio (TS-850, TS-950 etc.).
The problem is based in the radio's microprocessor. Some older Kenwood radio are not capable of communicating with the computer while the tuning knob is being turned. If you turn the knob smoothly and continuously, no matter how slowly, the radio will not be able to receive or respond to polls and the link will time out. Try using Kenwood-Slow as selected Radio. if this does not help please try to increase the 'transceiver timeout time' (right-click menu in the bandmap) in N1MM Logger. For example to 120 seconds.

TenTec

General TenTec information

The models below are supported, other models are not supported.

ARGONAUT V
JUPITER
OMNI-VI
- On the Omni VI+ the "Cde" item under menu 2 should be set to "off". Otherwise there will be collisions between the data sent from the rig when N1MM polls for
  data and the data that is being continuously sent by the radio which will cause erratic behavior.
OMNI-VII

The Omni-VII does not support antenna switching in "radio" mode. It is only possible in "remote" mode. So owners of the Omni-VII can not use the antenna switch macros.
Alt+F10 (exchange VFO) and CW-Reverse operation supported
The Omni-VII can not receive on VFOB.

ORION
- Uses default 56000 Baud and 1 stopbit and hardware handshaking.
- Firmware version 1.363 or greater needed.
- Note that the Orion does not support PTT on CW via computer command. This does work on SSB, but on CW, you need to set a parallel or serial port to assert PTT for that radio. Then use a cable from that adapter to pin three (PTT) of the aux port on the Orion. This is the black RCA Phono connector on the aux cable. By use of a Y connector, you can parallel your footswitch and this CW PTT cable.
- When using PTT and CW lines off a serial or parallel port. Be sure to go into the Orion CW menu and set "PTT in CW as" to the value "Mox".
- Defaults bandwidths: CW: 300/800; SSB: 2000/2800; RTTY 250/400
- CW on main receiver is LCW.
- Supports Digital Voice Keying (DVK) via the AUX port. Audio should be fed to the AUX port and NOT the microphone.
- - When no DVK is specified the front microphone gain will normally set to 0
  - - Microkeyer users: check out the Supported Hardware chapter regarding muting of the ORION microphone audio input.
  - When a DVK is specified for that radio the microphone gain will not change (mostly fed to the front microphone).
- When up/down pressed, turn on RIT if in S&P, turn off RIT if in running mode.
- Clear RIT by setting to 1 Hz not 0. Avoids turning off RIT.
- Narrow SSB bandwidth set to 1990 Hz to force the use of 2.4 kHz filter in auto mode.
- RIT can be changed using the up/down keys if RIT on. Note that you must turn on RIT from within the program!
- Swap VFOs using Alt+F10. This will replace the contents of memories 199 and 200
- Example Setup FSK/CW/SSB
  - In FSK or SSB mode the program uses the PTT input to key the rig.
  - In CW mode the program uses the PTT as the CW key.
    - Digital setup and MMTTY.
      - N1MM Config / Config Ports / Hardware Tab.
        
        Set the CW menu choice for the interface com port to DTR (Pin 4).
      - MMTTY Setup / Setup MMTTY / TX Tab / Radio command button.
        
        Checked the PTT button under DTR/RTS.
- Interface information
  - LINE OUT (74) is fixed level output (RCA connector)
    - Should be fed to LINE IN on the soundcard.
    - Yellow phono plug on Pin 4 of the AUX I/O cable assembly
    - NB this is a combined output for both receivers, use the AUX I/O port for separated outputs (pin 4 and 6)
  - AUX I/O port (80): AUX IN (pin 1) for transmit audio from the soundcard
    - Should be fed to LINE OUT on the Soundcard.
    - The AUX gain can be set under the SSB menu
    - Set the AUX gain to 65 and use the computer audio setting to drive the rig to 100 watts for RTTY.
  - AUX port: PTT (pin 3)
    - A transistor switch is needed from a serial or parallel port.
  - Works fine for digital modes but also for recording and the voice keyer.
  - Switch between MIKE and AUX via the menu.

Yaesu

General Yaesu information

The models below are supported, other models are not supported.
Required interfaces
- Newer models connect directly via a serial port cable.
- Older models need the Yaesu FIF-232C CAT interface (or compatible).

- Software handshaking is being used for all models.
- Yaesu uses by default:
  - Speed: 4800 Baud Parity: N Databits: 8 Stopbits: 2 (!)
FT-100(D)
- The FT-100D has an internal jumper for either CAT/TUNER or LINEAR. This should be set for CAT/TUNER.
- Configure the radio as FT-100, 4800, N, 8, 2, Handshake, Tx=1, DTR=Always on or off, RTS=Always on or off.
- Needs a standard FT-100 CAT cable (CT-62).
FT-736

Not supported and probably never will be. It seems that once the radio is controlled by CAT it can't be controlled by hand anymore.

FT-450

Supported

FT-757

Select FT-757GXII as radio and disable the radio communications timeout via the bandmap menu option (set it to 0).
The FT-757GX does NOT send anything to the computer and the radio mode can not be set by the program so the radio control functionality will be limited.

FT-757GXII

Supported

FT-817
- 19200, N, 8, 1, Handshake, Handshake. FT-817 CI-V Baud "Hi". When using a USB/Serial adapter set DTR to 'Always on' and RTS 'Always off'.
- Bandwidth button in the bandmap is not supported (and not shown).
- There are some limitations in the available CAT Codes provided by Yaesu with the FT-817, FT-857 and FT-897.
FT-840

Supported

FT-847
- Split Operation does not work, because it is not supported via the CAT-connection. So it has to be done manually by the operator.
- RIT and XIT in the bandmaps are not working, because this is not supported by the FT-847.
- Also working for frequencies above 100 MHz.
FT-857
- Select FT-897 as radio.
- The FT-857 and FT-897 computer control lacks the ability to select VFOs which makes it difficult for N1MM Logger to function as well as other radios.
FT-890

Supported

FT-897
- Supported
- Bandwidth button in the bandmap is not supported (and not shown).
- The FT-857 and FT-897 computer control lacks the ability to select VFOs which makes it difficult for N1MM Logger to function as well as other radios.
FT-900

Supported

FT-920
- PTT via CAT supported.
- For filter settings see below.
FT-950

Supported

FT-990
- FT-990 and early FT-1000 had a design problem in the CAT interface. It used an open emitter transistor on the serial out line. That worked fine for TTL HIGH (+5 V) but some TTL to RS232 interfaces did not have enough load to cause the output to go low ... the interface would
  "float" in the undefined logic state between .3 and 3.5 volts. The solution is to add a 1.5K Ohm resistor from "serial out" to ground. When using the ARRL handbook design the 1.5k resistor needs to be added between pin 1 of the 7417 (which is pin 2 of the DIN) to ground.
- For filter settings see below.
FT-1000(D)
- Cat control will not work with FT-1000D internal software version lower than v6....most older ft1000d's have version v5.8... you need an update!
- Older versions do have a CAT control problem. Check out the infromation with the FT-990 (above).
- If the bandmap/frequency is not updating, the radio probably is in Mem/Tune mode. Deselect using the VFO/MEM switch.
  - The program forces the radio at startup from Mem/Tune mode in VFO mode to avoid this problem.
  - For filter settings see below
- Please see also Key Assignments (Alt+F12)
FT-1000MP (Mark-V)(Field) (do not select when using a SteppIR antenna)

Please see also Key Assignments (Alt+F12)

The program can't send CW via the MP's serial cable. See the help for how to build a CW interface

If the bandmap/frequency is not updating, the radio probably is in Mem/Tune mode. Deselect using the VFO/MEM switch.
- The program forces the radio at startup from Mem/Tune mode in VFO mode to avoid this problem.
- The indicator should show VFO.

Use a straight serial cable

4800,N,8,2 and DTR and RTS set to "Always Off"

A big issue with the FT-1000MP is that you cannot set the radio to split with VFO-B as the RX. Well, you can, but you cannot control whether you are listening dual, or just VFO-B from the computer. You can detect it, but not set it. The user will have to press the main RX button to turn off the main receiver when split from VFO-B. Note that Alt+F10 will swap VFO A & B frequencies. That is very useful in this case.

Optimum configuration for those who wish to operate AFSK and/or PSK. There will be an 85 Hz display offset between RTTY and PSK but that is minor.
PKT is LSB with the frequency display shifted by 2.125 KHz (or other user defined offset at menu 6-4). It also selects audio input from the PACKET jack on the rear of the radio, disables the processor and mutes the microphone. Finally, it offsets the filters so the narrow filters are properly placed (centered as specified in menu 6-5).

Using QMB memories
- When doing a QMB RCLl press M>A until it transfers the QMB frequency to the VFO. After this it should work as normal, but you lose the original frequency that was in VFO-A.

FT-1000MPSteppIR

Select this FT1000mp when using a SteppIR antenna.
This selection is optimized for the combination of an FT1000MP and the SteppIR antenna.

FT-1000 series, FT-990 and FT-920 Setting filters . Simply right-click on the bandmap and you will get a menu which includes "Set transceiver filter codes" ... there are six submenus: CW Wide, CW Narrow, SSB Wide, SSB Narrow, Digi Wide and Digi Narrow. In my case the commands for SO2V are:

The settings below will work for the FT-1000, FT-1000D, the FT-1000MP, the FT-1000MP/MKV and the FT-1000MP/MKV Field (or any combination of two FT-1000 "family" of rigs in SO2R).

BandWidth	VFO-A (main)	VFO-B (sub)	Filter	Remarks
2.4 kHz	0 0 0 0 140	0 0 0 128 140	SSB Wide or Digi Wide
2.0 KHz	0 0 0 1 140	0 0 0 129 140	SSB Narrow or Digi Narrow	will use 2.4 kHz on VFO-B
500 Hz	0 0 0 2 140	0 0 0 130 140	CW Wide or Digi Wide
250 Hz	0 0 0 3 140	0 0 0 131 140	CW Narrow or Digi Narrow	will use 500 Hz on VFO-B
6.0 KHz (thru)	0 0 0 4 140	0 0 0 132 140

The VFO-B (sub) only supports bandwidths of 6.0 KHz, 2.4 KHz and 500 Hz.
For SO2R (two rigs) configure the two bandmaps the same.
Some notes:
- "Duplicates default filter settings" is appropriate to the FT-1000 MK/V and Field only. The FT-1000/D/MP permit more flexible filter selection.

The FT-920 does not support 2.0 KHz and 250 Hz filters ... it might make more sense to revise CW and Digi settings for 2.4/500 Hz (0 0 0 0 140 and 0 0 0 2 140) filters.

Even though the FT-920 lacks the second receiver, the FT-920 permits selecting different bandwidths for each VFO. The CAT commands are the same as those for the second receiver in the "1000" series: 0 0 0 130 140 selects 500 Hz and 0 0 0 128 140 selects 2.4 KHz.

The FT-990 commands are the same as those for VFO A in the "1000" series of radios.

FT-2000

Defaults to: 4800 baud, 8 bits, no parity, 2 stop bits. Set DTR to always off and RTS to Always on.

If the above does not work try to set also DTR to always on.

When using a 3 wire cable (TX, RX and ground) set CAT RTS=disable on radio (default is enable). This cable does not have DTR or RTS connected. Other radio settings like CAT TIME OUT = 10 msec and CAT RATE=4800 can stay as they are (default).A three wire cable should also work with USB serial adapters.

FTDX-9000
