qnh and qfe pages don't match. --Gbleem 16:54, 27 December 2005 (UTC)

I'm not sure how best to address it (this article, or in a new article with a cross reference with this one?), but QNH is also used in amateur radio, and has a totally different meaning. It's a special "QN" code defined by the American Radio Relay League (ARRL) on CW (morse code) traffic nets. In this context, QNH is transmitted by the net control station to mean "Your net frequency is high" -- suggesting that the other station tune his transmitter downwards in frequency a little in order to be more closely aligned with the frequency that the net control station is using.
