When the ps is activated the radio displays a green light for a second or so. Does the green light mean anything?
After the green light goes off and I press the radio button the radio displays the message "Shutting down... Error PSH1V5-4.10" and a red light flashes continuously. Does have any further meaning?
After I press the radio button again the message is "Shutting down" and a very brief additional message that I could not read and shuts down. Does that sequence have any further information?
measure voltage at the power poles with radio off turn on and watch the voltage do this before the above and after. please respond back with results. 73's K4ATR
So, I did not have this problem, exactly, but I did have one that was power related. I run a lot of AM and a few people commented that they heard a very slight bit of distortion. That got me looking. While using the stacks program I noticed that the internal voltage was dropping .7-.8v @ 100W out. My power cord needed to be ~ 6ft long. Three simple fixes took care of the problem. First, I made a new power cord using #10, super flexible silicon coated wire. I found what appeared to be a very light white film on the main fuse’s blades. I cleaned them and applied, very sparingly, some conductive silver grease to the power connector and to the forks on the two internal fuses. Now, under full load I typically see a drop of .1v, occasionally .2v. No more reports of distortion. I shared this info with FRS and suggested they consider using the conductive grease. Never received a response.
