Jerry,
RE: 14149.9 kHz ---
I would not be comfortable cutting it that close in USB unless I was
absolutely certain there was absolutely no energy in the SSB audio 0 to
100 Hz range. I would not trust any transmitter (no matter how good) in
that regard. Keep it all within the band limits to be safe.
