Howdy folks. I have said radio in title on the bench and have no mic for it. CB Tricks shows this rig has a standard 4 pin. My JFK has factory 6 pin. Does anybody have the proper pinout? Does this radio have the same pinout as the Lincoln II, Grant II or similar? Thank you much in advance.
 

1 Modulation
2 RX
3 TX
4 NC
5 Ground
6 NC

This Pin-out covers the 6 pin President, but there's one major difference. The older President's use a Dynamic cartridge and the newer President's like the JFK II use an electrolytic cartridge. I believe the JFK you're talking about uses the old school 500 ohm dynamic. Pins 4, 5 and 6 are used for up and down buttons in some models. The middle Pin 6 in that case has voltage,avoid it.

    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
