Re: [IRCA] FM DXing on Ultralight Radios
Paul: Here are some good sites to get you started (although not
necessarily geared toward ULR's).
www.dxfm.com
and
http://pages.cthome.net/fmdx/
and
http://en.wikipedia.org/wiki/TV/FM_DX
Summertime Es (or E-skip) is good fun on FM and you don't need a huge
antenna (even hear Es on car radios).

I for one?would be very interested in such an effort and to learn more
about FM DXing.
?

Hello John C. and Kevin,
There is indeed some serious interest in FM DXing with Ultralight
radios, but those of us with interest in this "niche hobby within a
niche
hobby"
have been reluctant to use the medium-wave DX resources of the IRCA and
ultralightdx Yahoo list reflectors to disseminate information and
technical
suggestions for promotion of this special activity, surmising that it
would
not be
suitable for the accepted AM-DXing orientation of these important
forums.
In general, the best performing AM-DX pocket radios are also the
best
FM-DX performers, with the Eton E100 and Sangean DT-400W both
exceptional in
FM sensitivity (the E100 with a whip antenna, and the DT-400W with its
headphone-wire system). Obviously, serious FM DXers are not likely to
be
satisfied
with these simple antennas for chasing serious DX, and I have
experimented
with the inductive coupling of FM 2-element cubical quad antennas to
these
simple antennas, with very promising results. Any FM DXers with
effective
external antennas can inductively couple these to the Ultralights, and
receive
a
monstrous boost in signal strength for DX (in some cases, impedance
matching
networks can be useful). I have an external FM loop antenna on my 40'
tower
pointed north, and almost all the Vancouver and Victoria (BC) FM
stations boom
in on the Ultralights, when inductive coupling is used.
If there is sufficient interest in this FM-DX aspect of Ultralight
DXing, I suppose the best option would be to form a distinct group
specializing
in the promotion of this activity, rather that to attempt trying to fit
it in
to the AM-DXing resources. A separate "ultralightfmdx" Yahoo group
might be
an option, assuming there is sufficient interest for such a
development. Any
comments or suggestions would be most appreciated.
73, Gary DeBock
