[R-390] MB Connector Use

[Flowertime01 at wmconnect.com]

David,

You commented,

The R-390 used BNC connectors.  Why Collins chose to change
the connectors for the R-390A I have no idea except it might have been a
matter of space or cost? 


If you were a 33 working on these things 8 plus hours a day 6 days on and 2 
days off, you soon thought the MB were a lot easier to work with than the full 
size BNC. Back in 68 - 75 it looked like a good idea.

I found a bunch of these one time in San Diego and sold them all at cost to 
the R390 group.

I also found a bunch of 3 inch coax with Male BNC on one end and the male MB 
on the other end. these make nice adapters from the signal generator to the IF 
deck.
These were from Murphy's Surplus in San Diego. When last there in 04 there 
were still a 100 or so of these in a bin. I had sold these at cost until orders 
quit coming in.

Someone in San Diego mite drive out to Murphy's and see if any of these are 
still around.

You do not make any money selling this stuff to the R390 guy's After the time 
collecting E-mails, addressing bubble packs and doing postage plus parts cost 
its a break even on your lunch money.

You just do it as labor of love. Maybe someone near Mickey's Place can drop 
in to Skycraft and see what the potential is to make us an offer.

See what on hand, find the cost, Think about postage and a padded envelope 
from Staples and offer up a price. See how many you could move as a one time 
offer this summer.

I had good results accepting checks from the Fellows.
