Hi. Not real hopeful here, but thought I would throw this out. Looking for the schematics for the MTR2000 UHF 100 watt amp. Looking to find the band identifier resistors and play with them. I would also be willing to purchase a manual if anybody has one.
The band identifier resistors seem to be the same one as on the VHF amplifiers, but the values are probably different. There's an article about making the 100w VHF amp work in the ham band that may be helpful.
There seem to be TWO resistor pairs. R4560/4564 seems to determine the power and possibly range split. Another pair might be used to determine the band. The 100w UHF PA has 15k (153) resistors installed for R4560/4564. The 100w VHF-hi PA has 1.5k (152) resistors there and the 100w VHF-lo PA has 15k (153) resistors there. Whatever they do, it doesn't make any logical sense yet.
