This opens up a big can of worms. Take it from one who has done a
few hamateur/900 Maxtrac conversions.

First and foremost: Programming is only part of the effort. You
can use the well-known 'shift-key' trick, with the stock Maxtrac RSS, to
enter the frequencies for 900MHz amateur systems. HOWEVER -- just
because the radio takes them does not necessarily mean it will work
without modification there.

One thing you need to be concerned with are modifications to the
VCO to even get the thing to cover amateur frequencies. Next, you need
to replace some filters in the receiver section so the front end won't
be deaf as the proverbial post at amateur frequencies.

Info on the (extensive) modifications required may be found at
these links:

down, look for '900MHz Amateur Radio Conversion')

coverage conversion. Not for the weak of heart or electronically
unskilled).

Happy hunting.
