[ICOM] Fwd: [OKtraders] New Icom IC-7300 HF/6m XCVR Introduced

[Roger (K8RI)]

Worse than brain surgeon, I was a computer jockey via a BS in CS with 
work toward a masters (at age 50 - so I'm a slow learner!) that was 
interrupted by a good job offer.  I waited until I could afford to go to 
college and had learned how to study.  Before college, I never had to 
study, so I didn't. That made my first college attempt rather short.  (I 
quit before I failed <:-)

My hands shake too much to go cutting in sensitive, or life supporting 
areas.

  My second foray into college was at age 47 after many college courses 
taken at night.

They did tell me I was the third student in the history of the 
university to build a compiler using current state and next state arrays 
which means nothing to people unless they are into computer science.  In 
graduate school compiler design was the same book in two, 4 credit hour 
classes. In undergrad, it was all in one term and 4 credit hours, so 
some of the grad courses were easier than undergrad. That was "some", 
but not very many!

CS is more the science of computers and programs although there is some 
programming involved..  Given a string of letters and numbers, we would 
have to calculate the speed on specific networks, or compare the speeds 
of various programs compared to others. Lots of calculus.  Database 
design had us working with what are called normal forms. (what you could 
throw away in compression and still get back to the original data).  I 
couldn't do half that stuff now.  I graduated in 90, 26 years ago.

That's why I'm interested in the algorithms used for adaptive 
predistortion.  I spent several hours going through papers on the 
subject last night, but they kept referring to specific programs that 
left me hanging. <sigh>  I need a plain language explanation for many of 
the parts (or need to write one), a subject that brought several 
requests to write plain language books on technical subjects.  Most 
engineers and PHDs write for others at their level in their areas of 
expertise.  I do understand that, as the more I learned the more 
difficult it became to put into plain language for non CS people.  The 
simplest math I did was 5 level simultaneous equations.  From there it 
got tough<:-)  Take adaptive predistortion. We would have had to 
calculate the speeds of various incarnations and compare them to each 
other, resulting in the fastest program variations, or fastest sections 
and the results from the algorithms.

I spent my last working years as a computer systems project manager for 
a large multinational corporation.  I should have stayed a few more 
years before retiring.<:-( <sigh>Hindsight is so much more accurate.

I see more of my dad's handwriting every day. My left hand was useless, 
but it's slowly coming back, but I doubt I'll be playing guitar, or 
doing competitive trap shooting  again, any time soon.

I used to install UHF coax connectors in just a couple of minutes. Now 
it takes near 10 to 15 minutes using crimp connectors.  The use of that 
left hand sure made a lot of things much easier, or in many instances, 
possible.  I don't think I'll be running CW on FD any time soon, either.
