Support for PTT control line #21

Closed lu7did closed 2 years ago

lu7did commented 5 years ago

Hi,

If integrated with a WSPR beacon to form a transceiver a control line acting as a PTT is needed, it is required to turn own an amplifier but, more important, to switch the antenna from the rtl-sdr device and whatever it's being used for transmission (even the raspberry pi itself with programs such as WsprryPi or others).

Thanks in advance, Pedro LU7DID

Hi @lu7did ,

Technically, yep it should be easy to allocate a pin of the raspberry pi, and use it to drive a fet+relay. I will not do this for this project right now, but I will do it for a next project, a FT8 transceiver based on RPi. At some point, I will retro-fit this feature to rtlsdr-wsprd.

Thanks, 73,
