[VHFcontesting] IC-202 schematic and info needed

[Rick R]

I have an IC-202, this is an older Icom 2m SSB rig, portable. I need a 
schematic if anyone has or knows where to get, and also need to know from 
anyone who has one, is there a 4V DC voltage on the antenna in rcv? I am 
measuring 4VDC on the antenna jack, and this prevents me from using the 
IC202 as an IF with one of my microwave transverters. Thanks in advance for 
any assistance.
