[R-390] LF on the R-390 etc

[Don Reaves W5OR]

Nice find, Pete.  Thanks for sharing this site and your direct
experience.  There are numerous vlf converters available from different
sources - 'vlf converter' in google brings up thousands of hits.   Also
see QST, April 2002, for the AMRAD LF converter project.
I picked up a scruffy red Palomar converter at Dayton.  The specified
input range is 10-500KC, but it actually works well up into the BC band.
So, there are plenty of options for those who don't have a R-389 handy.
