What's your transmitter? Sounds like you have de-emphasized audio feeding
an FM transmitter.
If that's not the problem, it may be where you're taking the audio from the
Mastr Pro RX. As I recall there's two places to get it; one has a rolloff
around 4 kHz. Not a problem for most people since standard NBFM should
rolloff at 3 kHz, but if you're going for maximum fidelity you may want to
find the unfiltered audio point.

Even the unmodified Mastr Pros are a bit deaf on UHF (~0.5 uV for 20 dB
quieting); preamps are required equipment for that RX IMO. If the mod
wasn't done well, it would be quite deaf. How does it do with the preamp?
