Thatās frustrating, but there are some ways forward.
When you press the INITIALIZE button in the Rig Control/Hardware PTT configuration window, success gives no response, and failure generates a message. What do you see?
/dev/ttyUSB0 should have file permissions which allow the- user running fldigi to read and write. What are those file permissions on /dev/ttyUSB0?
Thanks for the questions. When I click āInitializeā, no error message comes up.
/dev/ttyUSB0:
crw-rw---- 1 root dialout 188, 0 Apr 26 07:34 ttyUSB0
PTT does work by shorting the sleeve to the nearest ring. Iāve put the radio into VOX mode and that is working until I figure out how to get RTS to work. Thanks!
After you get the PTT issue resolved, thereās still a lot more to be done.
Go to your terminal window and type alsamixer. Select digirig in the f6 menu. Select f5 to look at all settings. Move sliders so that everything is as close to zero db as possible. Select auto gain control and click m to mute it. Close alsamixer and type sudo alsactl store. Then exit terminal.
Turn squelch on your radio to zero and tune the volume knob until the colored diamond indicator at the bottom of the FLDIGI screen turns yellow, then back it down until it just barely turns solidly green. The setting at the bottom that currently says ā-12ā is an attenuator that can be increased to zero.
Make sure the cable is inserted very well. Really give it a hard push after your think itās in. Many of the Baofeng radios have questionable quality control at the K1 connector. It feels like Iām going to break some of mine before they start working correctly.
