What I was wondering was if you had tuned the exciter to somewhere other
than its intended frequency range like maybe the lower part of the ham
band with a 148 to 174 exciter. For reliable lock in the two meter band
(assuming a high-split exciter) you need to either replace the plug-in
band-pass filter with the low-split version, or modify it with the
correct parts, and change the core used in the VCO coil (L101). The
coil in the high-split (most common commercial unit) uses an aluminum
slug, where the low-split uses a ferrite slug that pulls the resonance
lower than the aluminum one will.
