No problem, I am going to recreate a new autostart from scratch an see if that makes any difference.

New autostart made no difference.

Operation appears normal following your suggestion.

I have the same problem, all files in proper folder, autostart script correct, grep p2app shows process id.
I can start the p2app manually, receive seems to work properly, however when trying to transmit the t/r
relay constantly cycles instead of holding steady. The p2app show v19 FPGA and v33 ...

Different power supply same problem. I am working with tech support now.

Thanks for your help.

I just tried the audiotest, I can still hear a little bit of the noise without the 20db boost enabled,
when I enable the boost the noise is very audible, I tried it with and without the mike connected.

I am getting a low frequency noise on my transmit audio. The noise sounds like a low pitch whine. I can hear
the noise on headphones attached to the G2 and a second receiver.

I am using Thetis and a Heil PR781 and a MXL BCD1, I have verified the cables are wired correctly, I ordered a second
set ...
