[Elecraft] FLDIGI on Raspberry Pi PTT issue with the K2

[Elmore's]

Please carefully read everything that follows to avoid repetition of the steps followed. What I have summarized here is the result of MANY hours of work and extensive troubleshooting time via email with 2 incredibly helpful and patient hams.

I have an RPi 3 with FLDIGI and WSJT-X installed.

After MUCH effort over the past 6 months I have WSJT-X working. My problem now is that the PTT on the FLDIGI does not work.

The PTT on the WSJT-X does work. It's underlying rig control is Hamlib. I am using the Elecraft USB to serial adapter connected to the proprietary K2 serial cable.

Note that I have successfully used the K2 with a Windows PC running FLDIGI and WSJT-X for some time.

I have configured FLDIGI for RigCAT. It communicates with the K2 (frequency, mode, filter selection) but no PTT.

I have also tried Hamlib but it will not initialize.

During an extensive troubleshooting process over the past 3 weeks with a ham on the Yahoo FLDIGI RPi group I tried FLRIG. It is fully functional with the K2 but when I try using it with FLDIGI nothing works – no frequency control, no PTT, nothing! By this I mean that I am trying to use FLDIGI for the control. I have verified that I have all the correct settings in both FLDIGI and FLRIG with the ham that has been helping me. As a sanity check I installed FLRIG on my Windows machine and successfully ran FLDIGI there.

Has anyone had similar issues?

Thanks for any help.
