In the 1954 ARRL book: "Single Sideband for the Radio Amateur," W2UNJ 
describes a phasing exciter. (The book was $1.50, by the way.)

The equipment is long gone but as I recall, the plus or minus mixing 
scheme reversed the sidebands. This is the case for phasing exciters. 
My recollection was a crystal filter system which was not the case.

My point - as a throw away comment - was to recall the history of why 
bands below 20m use LSB as the default SSB mode. And it was because of 
the phase reversal due to the mixing scheme.

Meanwhile - has anyone looked at the I zero CG posting and is thinking 
about tinkering with putting a K1 on USB CW?
