Re: SDR Console to PlutoSDR, no TX on one PC, fine on another??

Hello Joanne, (got it right this time) ;)

Sunday, June 6, 2021

It turns out NOT to be anything to do with SDR Console at all, at least as far as I can tell Joanne.

I THINK I have fixed it. A very odd problem. I tried swapping the ethernet cable to a second port on the main satellite PC and suddenly I could transmit again. Why I have no idea. And why it even has two ethernet ports I do not know, either, one is just marked Ethernet, the other IBM Ethernet. I seem to recall having to load two different drivers for ethernet on this IBM motherboard, too.

The Pluto, pre amp and PA are back outside in a box under the dish, so I can't say if basic USB connection for TX is also working again. I don't want to mess with it :)

I then swapped the ethernet cable back to he original port on the main PC, and it also worked again there. Maybe the connector plug contacts were tarnished, who knows?

I would like to know what was going on, as I am concerned it will occur again, but for now all seems OK and I have had two nice contacts on SSB with excellent reports. Bloody computers!!

Thanks for the reply and take care.

Best regards,
Chris 2E0ILY
