- yup we've done that around here some times. Made it hard to hear each other :-)

How do you deal with the dearth of available frequencies? (There are 720 of them, and we only get 2?) Some people use some other frequencies in the av band that are not "official". I've tried using some old Sprint cellphones with the Direct Talk feature, they work as walkie-talkies (peer to peer, no cell towers involved). Free from the congestion on the FRS bands. The stumbling block so far has been finding/making suitable PTT headsets. And they don't do VOX.

Interestingly, the US Hang Gliding and Parachuting organisation has got themselves five chat frequencies assigned in the "Business" band! 151.625 MHz, 151.955 MHz, 151.505 MHz, 158.400 MHz, and 151.925 MHz

That's out of the range of airband radios.
