I need an off the shelf mic pinned out for my Washington radio's for testing. Cant find pin out listed in ads for uniden radio's. Any budy knows would be great. Thanks everyone. Mac
 

Mark,
For the 5 pin microphone (Uniden Washington with 8719 PLL) see the link below.

http://www.cbtricks.com/radios/uniden/washington_mb8719/graphics/uniden_washington_mb8719_sch.pdf

Bottom of the schematic about the middle of the page.

I read it as:
Audio-1
Shield-2
RX-3
Common-4
TX-5

I have a Cobra 139XLR (same or similar chassis as a Washington with an 858 PLL) with a 4 pin mike plug.

The link below shows the mike pin out as:

Shield-1
Audio-2
TX-3
RX-4

Good Luck.

    Hello gentlemen and Ladies. I have the dreaded RCI-2990 receive issue where my radio gets distorted when people get close to my location. I found the C90 Capacitor, but I can not for the life of me find the C89 capacitor. Can or does anyone have a picture of the exact location of C89 ? Thank you in advance, Wes
