In the first place, those so called 18 mile range walkitalkies are only 5 watts power INPUT to the finals. They are only 800 milliwatt in the FRS mode. They are the cheeeeep ones selling for around $ 20 and operate on the GMRS/FRS frequencies in the FM mode. What is even worse, you can't even leagaly use them on the higher power GMRS channels without the proper FCC license. Last but not least, that 18 mile range, under the best of line of sight cases, only seems to work over water. You night be better off to get a pair of CB radios.

Legally, you can't. Under International laws, tarriffs and treaties, and in the US, under FCC regulations, radio communication equipment is designed and manufactured to operate within specified output power limits. It is even illegal to work on transmitting equipment, including repair, without a proper license.j3h.
