Re: Kenwood TKR-820 UHF

 

I have the same repeater. Great little machine!

I use an external power supply to reduce heat inside the cabinet, and can take with me for field expedient repeater?

Run it off external 12v supply....the internal is a switcher...they die like that if you haven't recapped it

Weird one for the experts... I have a TKR-820 that has been running for YEARS.? And before I got it, it was running for years!!!
?
After about of month of running (summer/winter no difference), it kicks off.? When I reset the power switch, it flashes red briefly and goes out.? If I leave it off overnight, I can come back in the morning, turn it on and work for another month...? Really????? How does one trouble shoot this???
