Hermes board from Apache Labs
What is the TX output power on your Hermes board? I thought they were +33 dBm. If that is the case and the loop back path includes no attenuation you may be overdriving the RX. {o.o} On 20221212 06:51

Audio feedback in headset
I believe there are two paths that mic/line input can loop back to the output without going through applications. I suspect you have this right, though. {o.o} On 20221212 04:19:18, sm6fhz wrote:

Prezactly right. There are also very thick heat conduction pads that could fill the space without fumbling with a dozen pieces of whatnot. Note that if you can hold your hand on it for 30 seconds with

Remote control of an antenna switch ???
You miss the point. SDRC can feed back the frequency it is set to locally via MIDI to the deck so its display can be updated and control positions can be updated as appropriate. The controls need mapp

Two SDR Console instances, each with perseus or RSP duo
I am not sure where you got this impression. SDR front end serial numbers are used internally. But, apparently, the editable name you give the the definition is the way you're apparently expected to a

Pluto: Interrupted transmit, usage via network
#adalmpluto
The switch does not matter. The Pluto is a USB 2 device that falls down to 100 M Ethernet. That means you must use the lower Pluto sample rates. Your tiny images are unreadable so how about trying ful

That is "if". Out of the box windows is loosey goosey updating time once a day and drifting through the next 24 hours. So that's why I suggested the single computer check. That ALSO must deal with how
