Thanks Pete, If I find anything I will let you know. 73, Denis

Hi Denis. On the 64bit OS, I had a look at VARA's log and it tells me that it is not communicating with any apps on port 8300.? That is strange, as the RMS - VARA HF session can see VARA on port

Hi Pete, I am having the same problem running pi5 RMS Express/VARA and VarAC/VARA and APRIS32/VARA. 73, Denis WB8SKP

Hi Ken and all ... I am having issues getting PTT to work with VARA HF .... My Pi5 has the latest (11JAN2025) 64bit Bookworm installed, with Pi-Apps and that is about all. It is all running on a

Hi there, I've been running a Raspi 4 with QSSTV and a Signal link to a TS-50 for the past four days, testing it, and it's working FB. I also used it for the ISS event, and it worked fine, too. For

Maybe the cap is defective. I’m no expert but it sounds like it’s pulling too much current, for some reason. You should setup an amp meter to find out how many amps are going through

WARNING +++++++ I purchased three of these (see URL below) a few weeks ago. Perhaps I received a faulty batch but all three of them performed the same. On a 'soak test' with an input of 14.2v and a

Sorry, don't have the details. I bought a 10 pack of them 4 or 5 years ago. I'm powering some weather radios, a couple Pi-Zeros, and a few other devices that take random voltage inputs. I think I have

I was running 2 Pi5's of of one of these without issues. Now that I have a 24 port router with POE+ on all ports, it's been moved back to my project bench 12A Buck Converter DC 24V to 5V...

Michael, which Buck Converters did you purchase? Will they handle 3 and/or 5 a? I have purchased B converters from Amazon but they provide either 2 or 3 amps. The RPI 5 likes 5A. RPI 4 likes
