where can we find one?



The technology is there,,you just have to -learn- it. Tell you
what,,think about part 15 transceivers,,,,think about chips,..... now
think about different modes,,outside the box....think about
UHF.....now,,,if you still are confused, please explain why automatic
hopping of freqs on the freeband is such a difficult concept for you.
Since you can't seem to grasp this idea, forget about even casually
mentioning digital sequencing to you,,,,you'd win the pool!!! : )



I've been watching this topic with some interest. IMHO the only true
method of SS is the direct sequencing method. Frequency hopping sort
of "cheats" the concept of a wideband and barely distinguishable SS
system. Direct sequence is also more secure than FH.

Nonetheless, frequency hopping is considered spread spectrum in
today's marketplace.

As far as using SS on 11 meters, well...... First off, there are no
commercial CB radios made with this technology. Even hams have been
slow to embrace it. That's not to say that enterprising experimenters
have not played with it on 11 meters. Utilizing cordless phones and
transverters might yield satisfactory results. I'm sure there may be a
few that have. But it's hardly in widespread use.

Hello, Dave

The problem would be SWR with the requisite bandwidth. Of course, if anyone
has any of those old Heathkit Cantennas

There is a thought. 1.1 to 1 SWR from something like zero to 30 MHz. Not
bad somewhat above too; just add oil and turn on your amplifier LOL.
