Someone got a DEAL there for $83.00 (if it works)


It's an Icom 211, of course it doesn't work.

I gave one of these to a friend, who also had one. He needed two to
keep one running. I always said that it was a tribute to his
character that I gave him an Icom 211 and we remained friends.


I, like many other owners of the IC-211, have one that still operates
perfectly. Mine has never failed since the day I bought it new. And
it still looks brand new.



Lucky you. One of my troubleshooting efforts involved fixing the
digital readout, which was intermittent.

I resorted to completely sucking all of the solder off and resoldering
every joint. After that it was very erratic. I finally determined
that one CMOS DIP didn't have 5 Vdd on pin 14 like it should have.
Further examination revealed that there wasn't even a circuit trace to
pin 14. Vcc went to pin 13 and apparently Icom used a solder bridge
from 13 to 14 to power the chip. When I cleaned off the solder I
broke the connection. A wire jumper fixed that but the Mickey Mouse
synthesizer module was hopelessly unreliable, especially while mobile
in motion.


I found that there were a few rivets used for "through hole" connection
to connect traces on
one side to the other near the synthesizer. I soldered those and the
synthesizer worked better.
Mi 211 sets on the shelf with a broken switch :-(
