I plan to use either a synthesizer I have been playing with, or some
incantation of the "Huff & Puff" stabilizer. However, I need to pick a
range of frequencies for it as that will have a dramatic impact on the
synth/H & P circuitry.
Since I have never spent much time on 10, I wondering what the common
wisdom is for where the SSB activity is on this band. I would like to
keep the tuning range down to 100KHz if possible, but especially with
the H & P idea, I could go to say, 500KHz.

28.3-28.6 MHz
