I can observe signal when I use usrp_fft.py.
But, How to know the SNR is good SNR?
When I use TVRX the signal very was clear, but the BasicTX was not.
In fact, I can use two RFX900 daughterborads to do the
./benchmark_tx.py -f 900M and ./benchmark_rx.py -f 900M.
I think that’s becasue they have same frequency range (750 to 1050 MHz).
But, if I use the BasicTX and TVRX to do ./benchmark_tx.py -f 100M and
./benchmark_rx.py -f 100M, I can’t run if.
Because they have different freqency range?
TVRX daughterborad is 50 MHz to 860 MHz Receiver
BasicTX daughterborad is 1 MHz to 250 MHz Transmitter
Or because antenna ?
I buy the BasicTX, but not include antenna, so I use RFS900’s antenna
The result was TVRX can receive FM channel, But BasicTX can’t send
Thanks in advance.
