TX gets a "no supported device" where RX does not

[ksaye]

when I run the RX command, it finds the RTL2838 device

when I run the TX command, I get a 'No supported devices found' error.

Do you have a transmit-capable radio? RTL2838 devices are receive-only.

That has to be it! What affordable transmit-capable radios have you tested with?

P.S., great project!

I've tested with HackRF, but other devices (USRP, PlutoSDR, BladeRF, etc) should also work.

I'll close this issue off, since things appear to be working as intended.

Thanks and yes I agree close this.
