Hey there,

I was testing the P25 Tx support of OP25 with a hackrf but I am encountering strange behavior.
I am able to transmit "something" with the hackrf using the cmd
Code:
./dv_tx.py -p p25 --args 'hackrf' -f ./test.wav -Q 145000000 -q 0 --gains 'RF:0,IF:20'
inspired by Matt Ames (@MattSR):

On SDR# I am getting signal so something is being transmitted but the squelch won't open. Even when disabling squelch I am getting a signal (that seems distorted/noisy), check at DSD+ Source Audio window. I tried lowering the gain but the signal is still "noisy" so I figured I would ask the experts over here.

Thanks and Happy New Year.
