[ICOM] ic-211

[D C *Mac* Macdonald]

ALL of the early Icom synthesized radios had problems
with through-hole connections on the board.  It is a
real problem.  I have two IC-22Ss that the problem
has come back after attempts to repair them.  See
my comments on the second paragraph following this
one.

The best method is as follows. Every single through-hole
needs to be drilled out slightly and have special hollow
"rivets" installed in the hole.  Then, solder is flowed to
both sides and a good connection is made between
the "rivet" and the tracks on each side.  These rivets
(and tools for non-commercial installation) are made by
the Pace Company and some others.

I had  SOME  success, but not permanent, by taking
cut off gold plated resistor and capacitor leads and
using them to bridge through the board.  You can form
them into a "Z" (or half swastika).  Solder it to one side
of the board and then to the other.  It's a lot of work,
and you will have a devil of a time figuring out which
ones to do.  You need to do all of them and will probably
miss a minimum of 25% on the first go around.

Good luck!

I am looking  for  help with an  Icom IC-211  It seems  to have  the
intermittent problems every one seems to know   about, but  I  haven't  
found  how to
  fix the  problems..

I am 65 years old and not  a  radio technican but hopefully   with some
guidance I can redoe the solder connections that seem to be  the   weak spot 
in
this  radio..

Thanks  beforehand for any help.
