[RFI] tracking RFI with a marine direction finder

[Dennis Monticelli]

All,

Another useful and inexpensive tracking tool is a vintage marine direction
finder.  My particular model (Newmar NAV 101, but sold under many a private
label) is battery powered and has three bands: Beacon, BCB, and Marine (1.6
to 4MHz).  It has an RF gain control, sig strength meter, a BFO of sorts,
and of course a big lovely azimuth calibrated rod antenna that is capable
of nice nulls.  I found mine on the local CraigsList but there is always
eBay.  Many different makes and models were made.
