Hey Gang..

I have recently become interested in the 1750 meter band (160-180
khz).I have been searching the net for
information,circuits,reports,anything I can find!
I plan on homebrewing a TX/RX pair,once I do a little more research. I
have found a few Schematics,and plans for a couple different
transmitters,and antenna's,but no plans for recievers. Can anyone help
me out? I'd prefer to go the homebrew route,mostly for experience,and
for a learning experience. [snip]

A transceiver for this "band" was in the SEP 94 issue of 73.

I'd always wanted to put together a regen for this band. Regenerative
detectors are at their best when they are rather tightly coupled to
antennas that are electrically short. One reality of 1750 meters is
that any antenna one man can lift is bound to be "electrically short".
