I want to send serial data at 9.6 kB to a superegenerative receiver at 434 MHz using a Raspberry Pi and monitor the transmission with my sdr-dongle.
with rpitx I can do
rpitx -m RFA -i myrec.rfa -f 434000
but I don't have the rfa-file.
I understand that I can generate a rfa-file with something like
piam myrec_n.wav myrec.rfa
but that doesn't help me very much since I would like to create the rfa-file directly from my original binary data.
What is the format of the rfa file? Is there any software to create a rfa-file directly from the bytes to transmit?
Is rpitx -m RFA -i myrec.rfa -f 434000 the best way to accomplish my task?
Thanks in advance for any tip.
