Remember...regardless of any of the blister packs claims, they all put out..like ONE watt ERP.. MAX
And those Motorolas don't have CTCSS (privacy tones) which doesn't allow you to hear anyone else on that channel unless they're transmitting the same code you set your radio to listen in on. (remember, ANYONE can still hear your transmissions)
GB,
FRS radios are limited to 500m (1/2) W ERP
GMRS sets may transmit no more than 5 W ERP.
Thanks for pointing out the continuous tone-coded squelch system. We did experience minor interference - but we were in sparsely populated Death Valley. NYC would be a different animal and CTCSS is a definite requirement. Other Motorola systems starting with the FV500s have these “privacy codes”.

To be used legally, GMRS operations require an FCC license. GMRS radios share 7 interstitial frequency "channels" between FRS frequencies and have 8 channels dedicated solely for GMRS. Both FRS and GMRS are within the UHF range (300 MHz – 3.0 GHz). There are pros and cons to using UHF-v-VHF but UHF is used in FRS/GMRS for line of sight transmission, less interference to commercial systems, and is limited in its ERP to that end. The license to operate a GMRS radio requires an FC license good for 5 years for an $85 fee. Suggesting using another’s license for transmitting on GMRS could invite problems but people did similar things with CBs. The “non-blister pack” crowd of operators tend to have more expensive equipment, buy their licenses, and have been increasingly vocal regarding non-licensed operators with prodding from web sites like
http://www.gmrs.net.tc/ So be forewarned, there is movement by the FCC toward more individual enforcement and fines. If you want to be legal and license free, it’s getting hard to find a purely FRS handset anymore although ICOM does make one for around $49.00.
The ICOM F21GM Mutt talks about utilizes FRS/GMS channels and radiates 1 – 4 W switchable dependent on channel selection. Each handheld transceiver also weighs more than ½ pound (close to 11 oz.) with batteries and measures 2 1/8 x 5 1/32 x 1 1/2 inches. Each transceiver lists at $214.00 and can be found for around $150.00 on the web. But if performance matters and price is not as important you can move up to the lighter (7.6 oz.) feature packed Garmin RINO 110 with FRS/GMRS, CTCSS, GPS, Alarms, calculator, calendar, clock, lap timer, stopwatch, games for around $139 on the internet.
But Scott wanted SMALL....and decent
