Hi, I have an IC2100 that has a bad connection from the center of the SO239 to the main board.  The component broke and the schematic from Icom doesn't say what it is. I'm guessing it's a cap but not sure and don't know the value.
Does anyone know what this is?  Any help would be appreciated.

Thanks,
Larry / n4lew

Larry -

You posted this same question on QRZ, two days ago -- but never responded to the answers received.

IC-2100 Service Manual
http://www.repeater-builder.com/icom...ice-manual.pdf

PC Board X-Ray layouts in Section 8
Parts List for IC-2100 in Section 5

Page 5-3 of the Service Manual (Parts List, Main Unit)
L20 (Inductor, part number: 6110001550, LA-235) is first component from that point (W3) in the schematic.

Many small SMT parts (on both sides) of the double-sided Main Board on that radio.
You will find the parts at SO-239 RF connector on Main Unit (PC board) are Inductors (L) or Capacitors (C).
====
CONSENSUS:  JUMPER WIRE from SO-239 Center Pin to Main Unit (PC Board) at W3.

And, I answered it over on qrz. 

For the record, in case someone in future has the problem: 


W3 is just a Jumper.

Thanks for the replies everyone and the link to the service manual is exactly what I needed! BTW I did look over on QRZ but couldn't find my original post so I thought maybe it never posted..  Anyway I can get my radio fixed now. 

Thanks Again,
