[Icom] Problem with IC-251A

Fri, 7 Feb 2003 02:28:11 -0000

Maybe.  Using memory from LONG ago, which may be clouded....  there is one
diode in the PLL circuit labeled IC-251(A) only or some such ident.  It is
D-52 I THINK.....  but could be wrong.  I would check it first.  Remove it
from a 251A, and you have a 251E, the European 2 MHz (144-146) unit.  If not
the diode, something in that circuit maybe.

If I am totally off base, sorry.  It has been MANY years since I dug into
it, and I could be totally off!  At least you didn't lose any money on my
suggestion.

Good luck.
