Seeing all this talk about the TKR-820 made me thank about getting the TKR-820 I have working again. I replaced this unit 4 or 5 years ago when I was working at a Kenwood shop due to the following.
The repeater seems to work fine for a while 30 mins to maybe as much as 60 days and then one of the following seems to happen. The repeater will stop repeating upon getting to the tower site I would find the repeater in one of the following states. Rx'ing but not tx'ing Tx'ing (from local mic) but no rx No rx or tx at all I all cases there the power lite would be on and the front panels buttons and lites for each of them worked as you would expect. I only thing that would seem to get it going again was to turn it off wait 30sec or so and turn it back on, then it was good for 30 mins to upto 60 days or so. This repeater did this for a number of years and was gone thru multi times reprogrammed and retuned with no change. This repeater has been programmed with both a KPT-20 and a KPT-50 programmers.. Thoughts ? Any help would be great.

The -1 on the FCC ID tells you it is 450-470 split, and it will only be a standard reprogram, and tweak of the VCO and rx front end to get it down into the 440's. I did walk a -1 down into 420-430, but performance was pretty bad. Also walked a -4 (400-430) up, and it barely made it <450 rx and <445 tx, again, power out was low and rx was poor. But that's what to look for on a Kenwood commercial rig. The -n on the FCC ID tells you what split. No virus found in this incoming message.
