*** AH! ERROR.  I was thinking of my 3 KHz bandwidth HF rig.  I forgot
that the WARBLER only has a 1 KHz passband, so it would be of little use
as an SSB voice transceiver.  But still, it could be a cheapie foundation
for all other linear satellite modes using 1 Khz or less bandwidth..

I bet, however, that with a little tweaking of the color burst XTAL
filter, it could be made into a 2.7 KHz SSB rig....  ANyone?

I  would love to see this as a KIDS/Students approach to SSB operation on
linear birds...
