Hey Guys can you help me out? I was at a RC swap meet and saw a lot of FM radios fore sale in 72. I know we use 75, but my friend asked me why we couldn't use 72 and wasn't sure what the answer was. Can you explain it and should I may be picking up some of these 72s to get converted?
Well as I understand, 72Mhz is for air plane use in North America and 75Mhz is for land/water use. The two should NEVER be switched because IF you were on 72Mhz and running your sub and in the next field a person is flying their plane, your dive command could have the same affect on the person`s plane and not only would it crash the plane BUT it could hit someone and cause serious damage. PLUS if the government found out, you could see trouble.
Go ahead and buy the 72mhz radios, IF you get a good deal, then have them converted to 75Mhz and have fun safely running your subs without a care. Except mechanical/electronic/water leak failures. That`s enough to worry about, NOT using wrong Freq. transmitters.

P.S. BEST radios to go after 4 +++ channel FM radios
IF you do and your friend has extras, can you give me his contact info. I`m always looking for an extra radio?
Hi Jim,
There are also many 72 MHz radios for sale on eBay, just in case you can't find a good deal at your local swap meet. Call Radio South in Indiana to get the 72's re-tuned to 75 MHz, or maybe you can find a competent radio tuning tech in your area to do the job for you. If you live in an area where there is even a remote possibility of accidentally crashing some guys aircraft you won't believe the trouble you will be in.....both with the owner of the plane and the federal government. Both AM and FM radios will work, but FM is less prone to interference......just like an FM broadcast is less prone to static than AM.
Just my two cents worth.
