You can use the firmware from evariste
It switches a relais on gpo pin just fine
A usb relais only works if pluto is direct connected to your pc
But not if you control your pluto via ethernet with a network dongle...
The fw from evariste works fine for datv... And also in transparent mode in sdr console... In both cases the firmware switches a relais on gpo 0
Pluto switches tx on for a few seconds when booting
If you use two gpo pin and use gpo1 as inhibit signal then tx relais does only pull in on tx but not while booting
Use fw from evariste... And you do not need any usb relais....

The standard firmware from AD does not work with GPO, so you must use a USB relay.

Could I ask what is the current situation regarding PTT for the Pluto? Is it implemented via the GPO pins in the latest version of SDRC and does it work with the stock AD fw (0.31 I believe is the latest)?
I would like to use PTT with an SG-Lab Amp...
Great s/w, thank you.
