Running SDR Console on two Win 7 64 bit PC's one a laptop, the other a desktop. Both RX'd and TX'd fine to QO-100 using both USB and ethernet connections to a Pluto SDR, locally and remotely. Suddenly no TX at all from the desktop, but RX is fine.
A seemingly identically set up of SDR Console on the laptop triggers the Pluto to TX fine, via USB or remotely at the dish via ethernet and a USB to ethernet adaptor. The satellite hears the signal fine. I am testing the Pluto with a power meter on the output when checking the none working PC, it gives zero out. Laptop gives expected power. Same cabling used in both tests.
I have spent hours on this, reloaded SDR Console, deleted and recreated definitions, everything I can think of. The laptop is old, slow and struggling, but it does at least work. The main PC has been fine for RX and TX for weeks, I am not aware of changing anything. Any words of wisdom as to what else to try please? Thanks!
