D'oh! Hit the 'send' button prematurely. Meant to include the caveat that
while a regen will not likely have the selectivity or stability to separate
the 'loopers' around dot3 nor be good for QRSS, it will do fine for by-ear
copy of CW beacons at normal speeds and the sensitivity of a good one is
more than adequate for serious DX. Also meant to include the following links
for some inspiration:
http://www.webex.net/~skywaves/homebrew/12Vregen.htm

http://www.schmarder.com/radios/tube/

http://www.qsl.net/kl7h/12v.htm
While these ckts. were intended for higher frequencies, there's no reason
why appropriate tuned ckt. values couldn't be substituted for LF use.
