The only portions of what you have that WILL NOT move to 2M easily are the receiver and the PA. The exciter that you have is a 150.8-174Mhz one. Most of them will tune to 2M without any changes. If changes are needed, it's only to make the last two slugs tune correctly. (Change 2 caps)
The receiver's local oscillator chain will work OK on 2M (it's identical in component values.) You *will* need to change the helical resonators and the mixer coil, to work on 2M. The PA you have is useless on 2M. you need to find a 150.8-162 Mhz PA and transplant it. The PA's in the mobiles are VERY similar and can be transplanted easily. Keep the high split PA though, it will work good for spare transistors. Although often not a necessity, you should drill and adjust the Exciter band-pass filter for the least amount of loss. Converting your station is your best bet. Trying to find genuine 2M parts is VERY difficult if not impossible. That is why there is a great amount of conversion information on the repeater-builder site dealing with moving from one band to another.

We currently have a DVP unified chassis and have modified it to work as a repeater using the associated SCM card. It works fine with the commercial crystals, exciter and receiver it came with but it is in the Highest portion of the VHF band. We need to be able to tune down to 145.170 transmit, 144.570 receive. So we need the exciter, receiver and the PA for that range. We have the cabinet, power supply and the other cards we need. As far as we can determine, we need the DVP receiver board TLD8272B, exciter TLD5802A and the 138-150 MHz PA. In lieu of that, we would be interested in a unified chassis and PA for the 138 - 150 VHF range or the next VHF frequency range up (150-175) in hopes we can retune it to work for us. Any info or advice would be helpful and appreciated.
