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. 73 - Eric NO3M On 07/08/12 18:48, Jim Lowman wrote: > Not to rain on anyone's parade, Bill, but a couple of things > come to mind: > > -- I would think it a risky business to develop a transceiver > for a band that is not yet authorized for amateur use > > -- If most of us have trouble getting an antenna going for > 160m - wow - 630m? > > Just thinking out loud; not wanting to discourage anyone. > > 73 de Jim - AD6CW > > On 7/8/2012 10:42 AM, Bill Harris wrote: >> Wayne: >> An Elecraft Transverter for below 510 kHz would be well received, world >> wide.
