the discussion has answered my questions for this band and application.
Here in the Houston area I know of no 33cm amateur activity.
No hams appear to be affected.
Spread sprecturm is very robust hence should be immune from other users on that
band.
I enjoy QRP operation on HF -
-- I wanted to find out if there were users who would struggle with additional
noise.

Hello Mark,
What exactly are you concerned about? Someone using an unlicensed band
for human life-safety equipment or that they're using a piece of
spectrum that was set aside for unlicensed radio usage?
There are several rf bands that do not require licensing, they are my
home portable phone(900Mhz), and my networking ISM(2.4Ghz) and UNII-
based(5.2Ghz) network links.
tnx
