Q: I need to buy a mobile radio. Where do I start?
Start by determining the frequency range available for
your operation. If you or your organization owns radios, find out make, model
and exact frequencies assigned to your channels. Ask if it's VHF or UHF.
Contacting your local PTT office
or government organization responsible for radio spectrum assignments may be in
To work with each other, radios
need not be same make and model. They just need to be compatible. Compatibility
is determined by:
Model: that's the easiest. If we carry it, locate it by entering
the information in the Search window.
Frequencies: Can the new radio be programmed to operate on the same
channels as the old one? If both radios have overlapping frequency ranges, most
likely they can talk to each other.
Number of channels: if your operation uses, say, 16 channels, the
new radio must have at least as many.
Channel Spacing: Contemporary
radios support both 12.5 and 25 KHz channel spacing
Conventional radio: if your intend to talk
to others directly on the same channel, or use a conventional repeater, look
for conventional radio.
Trunking radio: if your operation consists of several independent groups of
people using a repeater (and other people don't bother you), you may be looking
for a trunking (trunked)
radio. Find out about the trunking protocol in use.
Ask your sources if the protocol is LTR(R), MPT-1327(R), SmarTrunk(R),
etc. The trunking protocol coupled with the frequency
range will determine your choices.
