[Elecraft] kx3 aircraft radio

[Bob Baxter]

Boy, this is all news to me.  As a career airline mechanic, since retired, I'm unaware of any HF radio equipment on board that is capable of operating on the ham bands.  The only HF carried on our airplanes was Automatic Direction Finding and that was receive only and emergency only.  Some Canadian airliners carried HF due to the distance between stations.  But what do I know, I've been retired 25 years.

 
Yes, the OFFICIAL use of radio equipment on board an aircraft for purposes of operating that aircraft requires type acceptance, but last I looked, the Captain of an aircraft (or ship) could authorize use of other radio gear onboard for other purposes. It's a judgement call, and requires that the captain be technically competent and able to assess that the passenger is also.
