Old unit stopped working. Has been really good until it stopped. Went away for 6weeks & there has been bad weather
here. Any tech who has worked/ know this unit like to help me. All my contacts in the tech field has long departed & I feel like the last one of my batch!! I now know no one still around anymore!! The CRT has no sign of anything on screen
. I suspect the TX has failed but not sure why I cannot see range rings & a bit of noise
. Does this unit rely on RX pulses to allow a display to be seen on the CRT?
Any tech helpers out there??
