Using other freqs to communicate between planes or ground?

"Peter Duniho"
shared these priceless pearls of wisdom:

-
-However, as I also mentioned, it's not an approved channel. It's reserved
-for ground test stations.

Nope. Subpart J is entitled FLIGHT Test stations.


-
-If you're going to chat on the radio in the air to other stations in the
-air, you should do so on 122.75, which is the frequency specifically set
-aside for air-to-air communication.
-
-I would also use 122.75 for student-to-instructor communications, when the
-instructor is on the ground with a hand-held for example, even though that's
-patently illegal (it's not an air-to-ground frequency, and the handheld is
-not a legal station for the purpose of transmitting).

A SINGLE instructor with a SINGLE student has been found to qualify for Subpart
K Flight School frequencies 123.3 and 123.5. The handheld is a perfectly legal
station for use in this service, but as I've pointed out several times, the
individual flight instructor (or their flight school) must apply for the license
and pay the fee.

The point of all this rambling is that there is a frequency available for almost
any use and almost any condition, but unless the stations at both end of the
communications link are authorized AND LICENSED on these frequencies, then the
communications FROM BOTH ENDS are illegal.
