RFI in the Car

I was out mobile, but I couldn’t check-in to the 985 Workbench. I had a weak signal, and I got a boost in interference when car powered off. It was mostly through the mobile antenna/coax, and it was enough to drown out W3GMS. I confirmed with spectrum analyzer on UV-K5.

I also had my AllStar 3 node but it wouldn’t connect either. The node connected to my phone hotspot fine, and it got an IP and all that. I could use the web interface or DTMF, but DTMF was flaky/slow. While debugging, I connected to the parrot node (55553) fine, but I only got “connection failed” from W3GMS (53085). I connected to W3GMS fine from home network the next morning.
