Has anyone done anything with a degaussing coil loop antenna?
Took a 27 inch Sony apart and the coil is something like 4 feet
across. Hooked it up to my Sony ICF2010. First thing I noticed was
very little background noise. Second there was QRM on 160 meters, 80
meters was very good. Performance started to drop off at 7 Mz, but
still useable. How are they constructed, do you treat them like a
coax loop? Any thoughts would be appreciated, Jerry
Don't know a thing about these coax loops people are constructing,
but your deguassing coil, in combination with the right value of
capacitance, should resonate at AM frequencies. Since you seem to
have a multi-band receiver, you should be able to find where it
peaks when you put a tuning capacitor in parallel. After that, it
is just adding capacitors in parallel to lower the frequency, or
adding them in series to raise the frequency.
Since those coils are designed to handle a fair amount of current,
the Q of the loop you make should be excellent.
