[ARDF] Ideas for 2006 USA ARDF Championships

[Dick Arnett]

Charles and Nadia already have the the two-meter keyed-carrier amplitude
modulation transmitters.

Can I suggest a compromise that would be easier to implement and should
meet
most people requirements ?
True, the full International rules specify AM, but it is more of a pain
to 
generate.
How about carrier-keying your FM transmissions ? Anyone using a whoopee
(eg 
Mk4) sniffer will not know or *care* about the difference. The DF
difficulty 
is pretty much identical to AM carrier keyed, but someone can still use
a 
handheld and offset attenuator easily. You can then still use your
existing 
FM transmitters (ex-handhelds or whatever) without building new
AM-capable 
transmitters. Just an idea....

Cheers
Bruce, (who did find the hunting the continueous carrier FM at
Alberquerque 
2001 last time made it artificially easier).
