There are plenty of LF converters to homebrew from, most very
simple including those using an SA602/612. Another is the AMRAD
LF converter, QST April 2002. PCBs can be purchased from FAR
circuits. I use three of those for dual RX and TX with a 14MHz
local oscillator and a K3 in transverter mode, displaying the
actual LF freq (Project:
http://no3m.net/index.php?page=600m ).
There are guys in the experimental group running antennas far
smaller than most would consider. However, while a short,
minimally top-loaded (relatively speaking), heavily base loaded
antenna will be grossly inefficient, all it takes is more power
to reach the ERP level, which will be low anyways.

I guess the number of participants would be rather low to start with but interest would increase with the availability of such an item. A poll of the amateur market would give a good indication of interest. If the numbers aren't there to warrant such venture, then maybe one of the small kit-providers might pick up the banner.
