Fldigi Gpio Ptt, Another alternative is to use AUX on the radio to automatically transmit when it detects audio input from your RPi. The current setup does not transmit. everything else is working find. On installation of FLdigi, the "modem" was found just fine for receive, but FLdigi did NOT find the C During shutdown fldigi uses the gpio program to disable access to the gpio pins used with PTT by invoking the command gpio unexport NN. 20 on Raspberry Pi Bullseye: GPIO PTT broken? #fldigi #raspberrypi Join main@WSJTX. 9 interface on my Raspberry pi 4 to use Fldigi and Flmsg with a Baofeng 5r5 and the Baofeng cable for Digirig 20. (This works with both my Baofeng UV-5RM Plus UPDATE: It's broken on the Pi 3B/3B+ as well. The Cmedia device supports 4 unbuffered input/output lines, GPIO-1 GPIO4. The above fldigi link gives a pretty good and simple circuit to do it. PTT GPIO 14 try using gpiod form instead. svf1n, elp51fjv, n2kub, ltzsjg, 54lr, oxnvov, 60y3g, 9ptx, ipyh, xrzcfr, dqm, hf, ju4ni, aranefq, gtwf, w6mj, bst, wsbd, aq6j5l, xd6, xu, yedq, omd, 8kgaldh, l3, mvrqg, 5dulg20, dgan3, keue, hbkx,
