[600MRG] modeling tutorial

[Edward R Cole]

Wow!  What a story!  What a life experience!

I moved to AK in 1979 which coincided with the 
end of the pipeline years (I left the LA area for 
the same reasons).  I also moved with no job 
in-hand.  I was lucky to meet several hams 
working for the BLM at the Anchorage ham club 
which I joined after a few months.  That led to 
my summer job 1980-81at the Fairbanks BLM Wildfire Center Radio Shop.

Pacific Telecom (PTI) had just acquired 
RCA-Alascom which was renamed Alascom.  I 1984 I 
turned down an offer to be engineer with them 
responsible for the state-wide mw sites for a 
seasonal Tech job for a oil industry telecom 
outfit (what a mistake).  It was the last job I 
would have until 1989 when I went to work as VHF 
marine radio opr during the Exxon Valdez 
cleanup.  If I had taken the Alascom job I would 
have certainly met Ed as some point.  So much 
more I could comment on - but will defer that.

Does it occur to any of you than Ed would make a 
perfect member of the 600m group!  We have no 
stations that far north but I suspect he would be 
workable from my location a lot of the time (350mi).
