At my job we use motorola HTs on UHF (400MHz+) using DPL/DCS
squelching. Sometime in the next few months we'll migrate to different
motorolas on VHF (150MHz+) using PL/CTCSS.

I'm a ham, but a somewhat inexperienced one.. I was wondering if y'all
could direct me toward a few dual or tri band HTs that would be easily
modified to tx those freqs, preferrably with the DPL/DCS capability
(since I think most radios come with PL/CTCSS), but if you know of one
that is super easy and only does PL, that would be great, too.
Comments on performance (ie intermod) are appreciated, too.

You really don't want to do that if you plan to transmit with
them, at least if they're amateur-only transceivers.

The reason can be summed up in two words: Type Acceptance. In
order to be legally usable on frequencies other than amateur radio, a
transceiver must be type accepted by the FCC for the radio service it's
made for.

This means that the manufacturer of the equipment submits their
design details to the FCC, and the feds then say 'yea' or 'nay' on
whether said design is found to be acceptable for the specific radio
service in question. Amateur radio transceivers do not require type
acceptance because of the non-commercial nature of the service.

Using a non-type accepted radio on frequencies outside those it
was designed for will get you deep trouble should you get caught. The
feds have already made this very clear in the form of the recent
crackdowns on truck stops and CB dealers selling illegal linear
amplifiers, and CB radios modified to go into the amateur 10-meter band.

Now, with all that said: It is perfectly acceptable to buy a
commercial type-accepted radio, and program amateur frequencies into it
(assuming you have the appropriate amateur radio license). God only
knows how many hams have done this already, myself included. In fact,
conversion of commercial gear to amateur service is a specialty of mine.

There's probably no need to post the mod, I'll find it on the
internet.. Unless you want to make it easy on me and link to it. :-)


Do you really want to risk both your amateur license and that of
the commercial service you're trying to talk to? Yes, both of them WOULD
be put at risk by use of a non type accepted radio.

If you must do what you describe, get a commercial transceiver and
stick ham frequencies in it. The other way around is just not a good
idea.
