A change of plan is required to make the WSPR beacon only operate certain days.. Not sure what that plan will entail as yet.
I wondered why it was still transmitting this morning when I checked it : The hardware watchdog timer that I added to the Pi resets the Pi board itself if no RF output is detected during a 7 minute sampling time-out period so my commanding off the RF simply resets the Pi due to the watchdog. The reset cycle repeats ad infinitum until it is supposed to be on !
Back to the drawing board until I can figure out a simple way to achieve the desired outcome. I have already figured out a complex way !!
