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

[James Bennett]

Jim -

For what it’s worth……… I run a KX3 with an RPI3. I have FLDIGI and WSJT-X. I use HAMLIB. I’m also using the same Elecraft USB—>Serial cable. It “used” to work quite well - both could receive/transmit/and control the radio. I use VOX to make the radio squeal. Somewhere along the line, something broke. I have NOT upgraded anything in FLDIGI, but I have gotten the RPI3 to a pretty current version of the OS. WSJT-X continues to work pretty much perfectly. But FLDIGI - not so. 

My very uneducated Linux guess is that something in the OS has clobbered FLDIGI’s ability to work nicely with the radio. Unfortunately, my use of FLDIGI was quite infrequent in the past, and when it completely broke, I didn’t spend a whole lot of time working on a solution.

Anyway, while our two setups are a bit different, there may be an underlying “thing” in Raspian that has crippled FLDIGI. Should be interesting to see if anyone else has the same issue, and if they’ve found a cure.

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.
