Cross band repeating (CBR) is a feature with some VHF-UHF dual band radios
that simply repeats what it receives on one band and automatically
retransmit it on the another band. This might be used when hiking or
camping. Your vehicle is on a hill and you are in a valley below. You can
take an HT with you and transceive to your mobile radio which will amplify
and cross band repeat to a repeater or other users. Some HTs can control the
mobile rig allowing frequency changes and voice feedback of the changes.
Several configurations can be used; Simplex-To-Simplex CBR,
Simplex-To-Repeater CBR, One-Way-CBR, and various modes of duplexing,
simplex, half, full, etc. Be sure to read the FCC rules regarding cross band
repeating. See Part 97.119 (a) Identification; Part 97.201 Auxiliary
Stations.
There are just too many schemes and different radios that can do crossband
to cover in detail here. Each manufacturer has their own method of
implementing cross band repeat, so you will have to read your manual for how
to set up and use the radio. An excellent series of articles can be found at
the ICOM page. URL:

support, then ICOM Technical Documents, then ICOM Crossband Repeater
Information. For Auxiliary or Remote Base operation, the radio manufacturers
have application notes for the various radios.

radios

I'm leaning heavly to mobile. I used to be on the CB a lot when I lived
in
a smaller town. Always used a mobile then.
Eventually I may figure out someway to use a mobile in a vehicle as a
repeater for a handheld. Has this been done for amatuer use already?
Thanks

Evaluate your needs whether HT or mobile or base.
Typically the new licensee purchases a Handi-Talkie (HT) for VHF/UHF,
but
later find they are using their first radio mostly in a mobile or at a
home
base station. A mobile rig can be easily switched back and forth between
the
vehicle and a base location and offers considerable advantages over an
HT.
This is not to bad-mouth the HTs, they are great for carrying in your
shirt
pocket or belt clip for pedestrian use, public relations activities, and
traveling light. Just be aware of their limitations and intended use.
They
certainly can be used for base and mobile applications, but better
antennas
and DC power sources are definitely something to consider when you
settle
in
on an HT.
A mobile radio on the other hand can transmit up to 70 Watts, operates
off
of car DC power or a DC power supply at the base location and can use an
antenna which typically is vastly superior to a rubber duck. Operating
range
will be considerably greater with the higher power and good antenna.
Prices
are about the same. So evaluate your needs and decide which starter
radio
is
best for you. Many eventually end up with both mobile and HT rigs.

I'm looking at getting my liscence (within the next week) and getting
setup
on 2m band. Anyone know of a good deal on a 2 meter setup? If not,
can
anyone recomend a good redio for beginners. I'm a bit of a tech
junky,
know a lot about electronics, programming etc. So I'm not too worried
about
ease of operation.
Any info would be great.
Thanks
Jonathan
