I currently have an HT220 setup to xmit/rcv on 151.xxx. Would like to
use it as a backup radio for police work on 156.xxx. Is it feasable
to convert this old radio or a waste of money? It is suggested I just
buy a new $200-300 radio. I'm sure I could install new crystals, but
is there more required?

The old HT-220 will move from 151.xxx to 156.xxx pretty easy. In fact you
might find the rx works before you tune it up.
The "Mid-Split" model went from 150-162Mhz if I remember correctly.
Transmitter tuning is very straight forward, all test points tune for max on
the meter. RX tuning is pretty easy too, however STAY AWAY FROM THE
DISCRIMINATOR. The "Front end" on highband (your model) is simple and easy
to tune.
A special antenna adaptor is needed to connect a power meter to the HT-220.
While they are rare, you CAN tack a lead to the antenna spring and ground
nearby instead. It's not "proper" but it will work.
Check out www.batlabs.com for more info and people that know Motorola's
all too well.
Hope this helps! Eddie (still owns a 6 channel HT-220)
