[Lf] Re: Query about LF

[Andre' Kesteloot]

Re your questions about LF.

a) transmissions: The European Amateur Radio operators have
been at it for
longer than we have, hence if you are interested in
transmissions
techniques, I would recommend "The LF Sourcebook" published
by the Radio
Society of Great Britain, and available from the ARRL.

b) reception only: the LowDown is an excellent publication
dedicated mainly
to LF reception, low power beaconing. etc.

c) AMRAD has a fair amount of expertise. We publish the
AMRAD Newsletter,
we run continuously 2 LF beacons on 136,745 and 136.750, and
you may want
also to attend our meetings: we meet every Saturday noon for
lunch in
Fairfax Virginia and the second Thursday evening of each
month in McLean
Va. All meetings are informal and technical. (No rules of
order etc.)
Details on http://www.amrad.org

d) equipment: if you only want to listen to stuff (beacons,
transatlantic
transmissions, ???, etc.) you will probably need a preamp in
front of your
receivers. Most receivers are fairly "deaf" below 250 KHz.
Another thing
that helps is a "e-field probe" or e-field antenna, aka
"active whip 
antenna" with a high impedance preamp up on the mast, away
from your roof.

Hope this helps
