When you say you can "hear" your repeater on 133.300, do you mean just
locally or can someone a mile or more away hear it? Locally, you will
spurs 80 or more dB down from your carrier (-80 dBc). These are of no
concern as they won't be detectable more than a mile or so away from your
repeater.
The G.E. Mastr IIs are fairly easy to convert, as are the MVPs (the
portapeater I showed you is an MVP). However, I think it would be easier
to just get your HiPro exciter cleaned up. If you have verified that the
spurs are coming from the exciter, you can put a pass cavity tuned to your
output between the exciter & amplifier & the spur problem will be fixed.

Is this happening to the exciter output, or is this a separate problem?
