Got a old (pre 90s) VCR that can manually tune to VHF-Lo, VHF-Hi, and
UHF TV frequencies. It has 16 preset channels. I swear one time I
heard two-way radio from a local utility company while manually
tuning. I suspect it was a inter modulation signal.

That got me into thinking why not modify it to extend the frequency
range from its default range of 174-216 MHz (VHF) and 470-698 MHz
(UHF)? I would imagine it might be possible to salvage the oscillator/
tuner for this purpose. Any thoughts?

Thanks in advance.

(P.S. I don't connect TV with this VCR; only use RCA jack for audio)

Well yes and no....
Yes..it would work.....
NO....it will have POOR performance as the front end is damn near deaf and
not stable.The IF is set up for a wideband signal, what you want is a
narrowband IF.
YES...it will hear strong signals nearby....
NO...the recovered audio will be VERY low.
NO...if it has any AFC in the front end it will go all over the place..

GOOD thought, but poor platform choice....
