SDR audio has static but no other audio signal

[nicolet]

Hello. I have a DX Patrol SDR on a Ubuntu 18.05 pc running CubicSDR v0.2.3. I have a waterfall and the software set for 146.52. I can hear static. When I key a radio on 156.52 I see the signal on the waterfall but speaking into the radio does not transmit voice audio. Any insight how to fix this is greatly appreciated. Thanks for your help.

Correction - 145.52. And here is the waterfall.

Try NBFM with a bandwidth of 12500

What kind of radio are you transmitting with?

What kind of radio are you transmitting with?

Yaesu HT. Now I can hear my voice very very faintly way back in the noise.

Might need some fiddling, I'm not familiar with the dx patrol or cubicsdr(4 or 5th time I've ran it)

Is your ht set to transmit and receive on different frequencies (offset)? If so, you want to tune the sdr to the transmit frequency, not the receive offset freq

Thanks for the input, no offset, straight 146.52 both ways. I continue to have a very small voice audio signal barely legible and way back in the weeds. Turning the sample rate down to 1.024 MHz helped slightly.
