I think you should be aware that Linux makes a distinction between a USB port and a serial port at a DB9 or DB25. It is even diferent in the devices in /dev folder of available devices. USB ports are often desiganted as USBn (i.e. USB plus a serial id from zero to n). and serial ports like RS232 are designated as TTYn (i.e. serial port TTY plus zero to n).?

The RS232 device common on older computers, can be connected directly to a serial port on your SignaLink if it of the serial port version. Otherwise, if you have a serial port version of the SignaLink,? use a USB port adapter for serial ports.

In the case of the USB version of the SignaLink,? it is plug-and-play and you have available USB ports on your computer.

As far as the 950 goes, you do not want to use the SignaLink to mic adapter unless there is no other options. That is due to the way a mic is handled internally (i.e. compressor, eq. , etc.) The preferred option is the aux port on the rear panel and the SignaLink adapter cable for the 950.

?

When selecting the USB port (or serial port) Linux may list it with the CODEC name rather than the port name. Same for FLDIGI or WSJT-X. Try using the port with the CODEC name first. There are also options in the SignaLink box that my need configuration. There is very good documentation on the Tigertronics web page. Some trial and error may be needed to get it set up properly.

I found this on another web page that may be helpful. Settings for the FT-950 (caution-baud rate of more than 4800 baud may not be reliable):

?

• SET RECEIVE WIDTH FROM FRONT PANEL TO MAX in PKT/USB mode, 2400.
• Noise Blanker and any receive DSP OFF, to avoid distortion.
• SET AGC TO OFF BY PUSHING AND HOLDING THE AGC BUTTON. You didn't know you had anything but AUTO, SLOW, MED, FAST, did you? Use RF gain to prevent overload on the waterfall. Keep the lower left hand bar graph below 70 dB and in the GREEN.
• 111 TGEN TX PWR = 35. This is nominal power for my Ameritron linear. It also avoids any ALC action at up to 20 watt power levels controlled by the PWR slider on the FT8 window, and the TX level knob on the Tigertronics box. It also covers you if something goes nuts to prevent overdrive to 100 watt level. It also protects the amplifier from overdrive, if you are using one. My Ameritron ALS-1300 works correct for most of the bands at this level, but beware that 12 and 10 meters should never be driven higher than the level stated in the manual.
• 064 J3E TX BPF = 4 - 26 or 400 to 2600 for minimum distortion when using an audio derived mode.
• 114 TGEN VOX = dAtA (only necessary when using VOX, NOT the hardware PTT on RTS in the RT systems CAT cable.)
• MODE-DATA GROUP:
  • 050 DATA DT GAIN = 30 (Sets range of TX knob on Tigertronics)
  • 051 DATA OUT LVL = 15 (Sets range of RX knob on Tigertronics)
  • 052 DATA VOX DLY = 30 (Not used with CAT control)
  • 053 DATA V GAIN = 50 (Not used with CAT control)
  • 054 DATA PKT DISP = 0
  • 055 DATA PKT SFT = 1000 (center of the spectrum in the waterfall)
  • BAUD RATE = 4800
  • DATA BITS = EIGHT
  • STOP BITS = 2
  • HANDSHAKE = XON/XOFF
  • FORCE CONTROL LINES:
    • DTR = HIGH
    • RTS = HIGH
      This actually is used to send power to work the Tigertronics box, not rig control.
    • PTT METHOD BOX, SELECT: CAT which is a much more positive method than VOX
    • TRANSMIT AUDIO SOURCE IS GREYED OUT (NO CHOICE)
    • MODE = DATA/PKT
    • SPLIT OPERATION = NONE
