In the days before voice telephony via radio, aviators used Morse code to c=
ommunicate. Shorthand abbreviations included a whole bunch of Q** codes. Th=
ese traditions are preserved now among the "Experimental Radio Association"=
 or ARRL, similar to EAA. Just as the FAA has an amateur or experimental ru=
le set, The FCC sets aside certain frequencies and authorises certain const=
ruction and operation of radios. Our main newsworthy interest and contact w=
ith regulators involves TVInterference, rather than occasionally dropping o=
ut of the sky in our entrepreneurial aerodyne. We have novice, technician, =
general, advanced, and extra levels of license and privileges, but no annua=
l physicals.
=A0When I trained as a Naval Aviator in the early 80's, we learned QNH is t=
he minimum altimeter setting in the military TAF forecast. Should you have =
a com radio failure, only one barometric altimeter (no GPS or radar alt), a=
nd can only rely on your preflight planning to get you safely down the appr=
oach path, why would it be important to know what the lowest possible altim=
eter might be?
=A0I wonder how many EAA members are also Hams.... I think the baby boomers=
 grew up in an era of extraordinary post-war military surplus aircraft and =
radios. I keep wondering how the rich landscape of potential projects and f=
ixer uppers, both in aviation and electronics, could be provided to today's=
 youth. It seems most of these gadgets have become appliances, off the shel=
f, or in the electronics too micro/nano to be accessible to the experimenta=
list amateur.

Ahhh tradition:
TAF KNKX 2309/2409 13005KT 9999 SCT060 QNH3005INS

What will you do, Marine, if your F-18 goes NORDO and the usual 100 foot=20
ceiling marine layer is rolling in? How will your procedure vary
=A0according to what time it is?

Enjoy
