Final Notes on IC-765 Mods

   Thanks for the MANY INPUTS received on IC-765 mods for VBT, higher power
out, sidetone tracking, front-end upgrade, and out-of-band transmit.  

   Most of the mail gave moral support on whether the mods are worth the
time/trouble.  That was appreciated!  Cutting into $2000+ solid-state rigs is
not the same as the S-40 and DX-100 from CD Party days!  I even got reading
glasses the same day tho' -- first!!

   I have already sent a long version with facts on the mod's to the few that
expressed interest.    If anyone else needs info, especially on the VBT, the
higher power, and the out-of-band transmit, just e-mail me direct.  If
interested in the front-end upgrade or sidetone tracking, I would suggest
contacting  LTA Industries and K3LR.

Best 73... Steve, W5KI/2

Hi Jim

You have that story correct.

W1TX did use a mechanical octopus to prevent more than one transmitter 
from transmitting at a time.  It was built by John Doremus 
W2ADE/W2TA/W0AW and was a fearsome looking thing with a huge aluminum box 
in the middle loaded with relays and a large number of tentacles 
radiating outward from the box.  Sort of like a modern day Wouff Hong.

Unfortunately I do not remember what was in the box.  And John is no 
longer with us.  You might try Roger Corey W1AX/JYH, Gary Foskett W1ECH or 
Pet Chamalian W1RM/BGD - they might remember.

I adopted the operating technique you mention as a defense measure.  All 
of the operating at W1TX was search and pounce using the octopus to keep 
you honest.  My partner that year on the other end of the octopus was 
Dave Sumner K1ZZ.  We sat across from one another and looked at the other 
guy for most of the contest.  The most efficient way to operate was to 
find a station to work and then press down the transmit button and gobble 
like a turkey until the other guy was finished transmitting.  

Little did I realize how useful that technique would be in meteor scatter 
contacts where the scheduled contacts sound very much like a bunch of 
turkeys or at best a used car auctioneer.

I saw the fax of the ad at Associated radio saturday morning. It is 
SIMILAR in basic design to the 100d BUT, has Collins mech filters, is 
limited to 150 watts, 2nd rcvr is "IN BAND" only. The quality of the fax 
was rough but, I did make most of it out. I will try and contact Dan 
there and see if I can get a copy and put more info out for all to see.

The modern octopus resides in software and a couple of transistors.

Subject: Coax in cold
Message-ID: <40mndj$o6q at>

I am considering moving to a place where it gets cold in the winter and was considering a crank up tower

The crank up would probably have to be cycled up and down during the
winter so I was wondering what would happen to the coax (i.e. snap, crackle
and pop).  I've always lived in sunny so cal so I'd appreciate a quick 
primer from one of you contesters from the colder climes.  Thanks & '73
