Hello, If it has the "New Improved" PA deck and he is below 450 MHz using one of the 450 to 470 MHz split radios is the problem. You can tell the new PA deck from the old by the Q-4 driver transistor. The old style was not screwed into the casting, It's a surface mount looking thing. The new driver is screwed to the casting and they also have copper colored "springs" over the top of both the driver and final transistors.
I just did 5 of these updates to my TKR-850's and tested them all on 442.15, none made rated power there but did above 450 MHz. To prove this he can always program the radio to a higher frequency and check it there.

Period. <---Sorry Jim but that isn't what Kenwood says. They spec the TKR's at 100% duty cycle @ 25 watts but they also plainly spec the 850 of being capable of 40 watts at other than 100% duty cycle (I can quote from the service manual if that helps) That his 850 wouldn't make more than 27 watts, even when programmed for hi power, indicates something is out of whack.
