I was not claiming that SCAMP *did* violate; I just had no information.
Given that SCAMP didn't directly link to or modify any GPL code, the
following is slightly off-topic...
By the way, a very good resource for what the GPL *really* does and
does not mean is at http://www.gnu.org/licenses/ .
My comments are interspersed.

To the best of my recollection, any signals within the passband would
prevent a transmission. Even fleeting ones like voice SSB, but it was
not as affected by wide band noise as much, even static crashes. I don't
know if it was more than what you ask, but I will say that most

I'm glad to hear that. It sounds like it's implemented the obvious
way, and thus should be very easy to duplicate. I'll try to set up a
test harness and see whether I can duplicate its functionality.
If I do, I'll report success here.

Thanks for your clarification of the GPL use in this case, Rud.
The reason for expecting Rick to GPL the code is because he said that he
was going to GPL the code. Pretty clear cut.

A good analogy of sharing spectrum between peer-to-peer and

Hello Rud,
How often does a remote users sending traffic through an automated
station have to wait due to an exasberated number of ARQ retries due
to stations purposely transmitting CQ's or whatever just because they
don't care that its not a two-way QSO that is inhabiting the channel.

Sure Dave.
I could have pulled the keyer from the other rig and plugged

I pretty much gave up on that idea.

Who really cares it's just pactor.
