I’m asking the same thing others have asked, but nothing that was suggested in other threads works for me. I’m going to try to exhaustively document what I’ve configured / tried.
I’m using a Mac running Sequoia 15.6.1.
I have a Digirig Mobile configured for CI-V. I opened it and it looks like the correct pads are soldered (the top row’s middle and right pads and the middle row’s middle pad are all bridged with solder.)
The Digirig Mobile is recognized by the Mac as a USB to UART bridge controller with Vendor ID 0x10c4 (Silicon Laboratories, Inc.). Its location is 0x00114100. This tells me the Mac can see the Digirig.
I got a “Icom IC-706 Digirig Cable Set”. The “remote” is plugged into the radio. The green end is plugged into the green port on the Digirig. The Icom Mini Din13 connector is plugged into the radio and the regular black end is plugged into the Digirig.
The 706-MKII has the following settings:
13 PTT TUNR: ON
25 CI-V ADDRES: 4EH
26 CI-V BAUD: 9600
27 CI-V TRN: OFF
28 CI-V 731: OFF
On the Mac’s Sound control påanel both the input and output are set to “USB Audio Device”. This tells me the Mac can see the Digirig.
In WSJT-X (v. 2.7.0) I have the following configuration:
Rig: Icom IC-706-MkII
Serial Port: /dev/tty.usbserial-11410
Baud Rate: 9600
Data: Eight
Stop: Two
Handshake: None
Force: DTR empty; RTS empty
PTT Method: RTS on port /dev/tty.usbserial-11410
Mode: None
Split Operation: None
Test CAT works. I can see the radio switch between VFO-A and VFO-B a few times and see the frequency shift and return to the starting frequency. This tells me CAT control is working.
Test PTT immediately turns red. No errors are given except the red button. The radio never tries to switch to Tx. The same thing happens if I choose Tune in the actual program.
Decoding is happening correctly. I see FT8 messages. Frequency change is happening correctly if I switch FT8 bands. This tells me the Mac is processing the audio going through the Digirig.
I’ve seen the Digirig troubleshooting PTT YouTube video. If I short the sleeve and R2 ring the radio switches to Tx.
However. I can’t seem to make the second troubleshooting step work. If I test continuity on pins 2 AND (3 OR 7) while Tune-ing in WSJT-X or by testing PTT nothing happens. This is a little hard to test with two hand, a connector, two probes, and a mouse button to press, but I gave it a good long try. It’s hard to prove a negative, but I couldn’t get it to respond to the Tune in WSJT-X.
So now I’m stuck. Any ideas? (and thanks if you’ve read this far).
