Strange TX Disabled and DAX error situation

Steve Blankinship AG4SO

Remote 6400 Operating SSDR 2.10.1, Win 10 64 bit. Ran for several days running SSB and Digital Modes. Turned it .on for a net and got a TX Disabled messaged then the link dropped with a message connection lost. Rebooted the radio no error message so I keyed the transmitter only to have the link close again. After two more tries including turning the radio off then on with a 2 minuet wait I had the same results I brought the radio home so I could properly test. On boot up I found the DAX showed the TX and RX in yellow. CAT showed no issues I cold find so this was puzzling with a TX disable message I de-selected then re selected TX and RX. Each came back to green after several seconds. I had to repeat this procedure on every band for both slices. After all appeared good so I shut down SSDR on the work bench desktop I was using and brought it up on main work station I use for remote operation. TX and RX on all bands again an alarm as before. Both computers are win 10 64 bit both using SSDR 2.10.1 Have not yet tried the Mastro, wanted to see if anyone has encountered this as it is a new one for me. Hope to understand in order to hopefully prevent repeating as the radio site is on a mountain.

BTW checked the DC voltage and current to the radio before bringing home, no issues found. I run a 35Amp Astron across a 12V AGM battery with a Epic Power Gate. I also used my antenna analyzer to test the antenna and feed system including antenna remote grounding and surge protector with no issues found.

Thoughts?

Hi Steve, it sounds like it could be RF getting in somewhere. Try at low power or into a dummy load to see if that helps.

My experience is that RF gets into the computer (more so than into the radio) via Ethernet cables and USB cables. Once I put ferrites on all of them, including cables not related to the radio, my issues went away.
