trying to run my hpSDR on FM 145mhz but is there a way to set the Deviation when you TX ??? I can se that in RX you can change it from 2.5k to 5k wide, the reason is that when I speak it sounds very "tiny" I have try to change the Mic level and also the TX-gain in the VAC1 ( I run my setup remote) but with no luck ???

Ben,
I don't know anything about transverter operations, or FM operations, with PowerSDR. However, it might be as simple as changing your transmit passband settings to be wider in Setup > Transmit.

Hi Scott
I found the "Error" as I am running remote I use the VAC-cable and I have the "VAC1 TX Gain" set to 0 but I raise it to 40 and then I have a god and strong voice on FM

That doesn't seem correct. You should be providing sufficient audio gain well prior to the VAC interface such that the Mic Level in PowerSDR is hitting between 0 and -6dB with VAC TX Gain set to 0dB. 40dB is a ridiculous amount!
