    Default cobra 29LTD classic d/k help

    hey gang.
    I have a 29 thats been peaked and tweaked but the d/k is too high for my liking. It's at just under 5. Going into a dave made 1 X 2.
    At 12 volts its at 2.5 but the car running is sending about 13.9 to 14.1 and thats sending my dead key up.
    Is there a pot that I can adjust to get my d/k down to where I want it? I won't be able to get it to my tech for about a week or so and really don't want to be without the radio. ( soldering isn't my specialty, I can do it if I have to, but need 4 extra hands to hold the magnifying glass :lol: ) I checked cbtricks but I couldn't find any help with my radio....just every other cobra 29 ( figures :mad2: )

    any help?

    thanks in advance.

    thanks Booty, knew I could count on you for a cut and paste. lol
    I knew about that one...or atleast the same mod under a different name from cbretards.com

    And I love that page, kinda slaps somebodies magic swing kit in the ass.


    but isn't there a way to do the dead key just by turning a pot?

    WOW, I really like saying POT:hurray::sifone::sifone:

    There is no pot for dead key on a 29. You can detune the radio to bring
    the key down, but your forward swing will drop too.

    If the slug is in L14, then you can adjust the carrier down some. If not, you will need to try somewhere between a 22ohm to 100ohm resistor on the pcb side across JP36
