4 years ago I use this code for PTT on pin 26 | 25 | GPIO.25 - so I can receive during the idle time
4 files are need
/home/pi/gpio/tx /home/pi/gpio/rx /home/pi/wspr137500 /home/pi/sked1
put the following in a script named /home/pi/gpio/rx
gpio mode 25 out
gpio write 25 1
echo RX
put the following in a script named /home/pi/gpio/tx
gpio mode 25 out
gpio write 25 0
echo TX
put the following in a script named /home/pi/wspr137500 /home/pi/gpio/tx sudo WsprryPi/wspr -f -p 0 callsign grid 23 137500 /home/pi/gpio/rx
put the following in a script named /home/pi/sked1 and execute ./sked1
while : do
m=date +%M
s=date +%S
echo -n -e $m $s "\r"

Hello,
Excellent program, running it on a continuous basis together with the also excellent QRPi board.
I would like to suggest the possibility of some (perhaps selectable) GPIO line to be raised when a transmission starts and lowered otherwise (or viceversa) so it can be use to PTT another stage.
In particular the posibility to switch antennas if We're also receiving in the same antenna.
Thank you, Pedro LU7DID
