Highly unlikely, best scenario on the GP340 is to get them to operate back to back on the same frequency. depending on frequency and power output RANGE OF A COUPLE OF MILES.

I have some Motorola rechargeable walkie talkies (in pink, oh the shame!) for comm between family members. & a Kenwood TH-D72 (wish I could take the time to finally work out what it's capable of) for my bob.

I have shied away from CB's for years cos of the low street cred value :roll:

However, it seems that now might be the time to invest mebbe.

Well there not digital and are listed as covering:

LB1: 29.7-42 MHz
LB2: 35-50 MHz
VHF: 136-174 MHz
UHF: 300-350 MHz
UHF1: 403-470 MHz

You would need the programming software and cable but you should be able stick them on PMR446 frequencies. There not really military radios but built to the US set of military standards which just basically means their drop tested and weather/dust sealed.

CB is:
01.... 27.60125
02.... 27.61125
03.... 27.62125
04.... 27.63125
05.... 27.64125
06.... 27.65125
07.... 27.66125
08.... 27.67125
09.... 27.68125
10.... 27.69125

11.... 27.70125
12.... 27.21125
13.... 27.72125
14.... 27.73125
15.... 27.74125
16.... 27.75125
17.... 27.76125
18.... 27.77125
19.... 27.78125
20.... 27.79125

21.... 27.80125
22.... 27.81125
23.... 27.82125
24.... 27.83125
25.... 27.84125
26.... 27.85125
27.... 27.86125
28.... 27.87125
29.... 27.88125
30.... 27.89125

31.... 27.90125
32.... 27.91125
33.... 27.92125
34.... 27.93125
35.... 27.94125
36.... 27.95125
37.... 27.96125
38.... 27.97125
39.... 27.98125
40.... 27.99125
So no it can't be used for CB.

can someone help me with a querie i have, after a long chat with a radio HAM he informed me that i would have to apply for a ham radio licence in order to leagally use a radio set but i can leagally buy one either online or over the counter but not us it (a bit skewed law there surely but hey ho) the question is ,when does it become ok to bring it out dust it off and use it ,the reason im asking this 1,more bandwidth ie hopefully more people 2,more range thanks for any help anyone feels they can give. At the moment i already have cb radios stored ready to use with allancillaries as do other family members just thinking about family up country

Hi Rincewind, you can legally buy a Ham Radio transmitter without a license. The only time you need a license is when you Transmit. you will also need a power supply rated at a minimum of 12 volts and a current supply of 20 amps if you want to tranmit. and a aerial for the frequency you want to operate on.

If you want to get a license try your local radio club. It will normally take place over a weekend for the Foundation license and the cost will be be from £27.50 which is the cost of the examination. More info can be found at http://www.rsgb.org/arls/foundation_licence.php

SWR Meters can be used on both Ham and CB Radios. It all depends on the power rating of the unit as typically Ham Radios can be 100 watts and CB 4 watts. SWR is a measure of the reflected power from a mismatched aerial. Another factor is frequency CB is 27mhz ham Radio covers any where from 1.8Mhz to 432Mhz depending on make or model.
