I have a nice HTX-100 10 meter, 25 watt SSB/CW transceiver in good
working order, that I would like to trade for a working TNC. I'm

Dave, how about a swap for a PK232MBX?

A somewhat off the current chain of thought...but what burns up the finals in
your transceiver with a high crest factor mode? Is it the peak power or
average power?
In SSB I can have a peak power of 100 watts output over an epoch but the
average power over an epoch is maybe 10-15 watts and
A friend of mine built one of those XR2211 demodulators...it did not
work very well on the real HF world. He left it aside and Hamcom with
just a 741 squarer performed better than that.
I built something inspired on the AN-93, but not a copywonderful !
It had two active filters, full wave

I have read from the SCS website that there is still throughput with P2
and especially P3 when down to maybe as low as -16 db below noise.
Others have claimed that Pactor 2 and 3 drastically drop off by the time
you reach -5 db S/N such as KN6KB's RFfootprints powerpoint on
Please allow my 2 cents worth.
KN6KB in his presentation of SCAMP to the DCC a couple of years had a slide
that showed where he measured P III with a channel simulator from KC7WW. I
showed that around -5 dB SNR there was still something in the area of 200 WPM
throughput.
I believe that you
Well, without measuring anything on a path simulator, P III works very
well.
Uses most of the good tricks on P II, like convolutional encoding (sort
of FEC)
Viterbi (maximum likelyhoodi.e. minimum repeats) decoding, and some
clever
speed change strategies.
P III improves in modulation,

I have typed this message twice, once in original format (see below)

That is odd, Andy! Here are my thoughts
Have you checked for an IRQ conflict with the keyboard? Is the
keyboard wireless? Have you tried a different keyboard on that PC?
Does the problem show up in all web-based situations, such as

As I am typ this , he CPU is at 10%. I have not ye checked for IRQ

if that makes a differnce, I guess not. I'll try a different
