Executive CB-68a Pinouts And How To Trick

[Joshua Francis]

OK so i have this amazing bus unit with a microphone capabilities.It is the panasonic cq-cm130u and i don't have any wires for the mic.So i was wondering if i could maybe get a pinout of the microphone that works with it.What i plan to do is short the "tx" wire (the 8.5v white wire) to ground on a switch to enable the 2 rca jacks in the back and wire up the mic to it.But anyways i would like to know cause i took the multimeter to it and i also took it apart and found out where everything goes.And there is 2 black (same connector: ground i know that one) and then there is a red and a white.And the red wire to the circuit board when followed to the board socket it says acc (or accessory) so i'm assuming that this is the "power" to the mic.And if i follow the traces of the acc then it leads to the power antenna wire on the harness directly but only reads like 10.2 volts.But the mic is 9v rating.And when i follow the white wire it goes to A LOT OF STUFF.Like 3 traces on it.It goes to an ic and resistors and it is all over the place.But the the one thing that interested me the most into it was the white went straight to ic ic250 or something like that and that is what i'm assuming what i would ground to enable mic function...Am i correct?Please help me with this or even better i would also like to know the pinouts when looking at the mic female connector from the mic itself the pinouts.THANKS SO MUCH

Please,anyone?

Never heard of it . . .

If you can, take a few pictures of the chassis with the covers off so that it may be possibly matched to another known radio chassis. That may or may not be the case. But it may be the best shot you have unless someone is familiar with that radio.

I think you may want to watch on you tube "Ham Nation #235" Bob heil will show you a lot. Bob is on almost every show talking about audio, and how to diy your mic, and others too.

i couldn't find him anywhere,thanks for replying

That make/model of radio. . . .

EDIT:
I see; it is a microphone...my mistake...
Never heard of it either - lol . . .
Then, take off the back cover and trace it out that way if you cannot get a pinout chart.

ohhh lol

 

[Joshua Francis]

does anybody know any info on the mic?Or the radio?

 

[Robb]

I looked at the CBTricks website, and it has no listing for that model and almost no info on Panasonic radios in general:

http://www.cbtricks.com/radios/panasonic/index.htm

Panasonic built those radios during the 70's when CB was a 'craze'.
No more craze. No more market. No more product.

While Panasonic radios look great, they are virtually 'unicorns' any more. No one has them, uses them, or have little to no info on them. I'll also bet it was built very well, as Panasonic didn't do things second rate.

IMO - your mic stands a better chance than that radio does. If you want an AM-only radio to get on the air with, I'd suggest getting a Uniden 76 or 78 model series radio and have a blast. Solid quality build and info and parts abound for them, including service manuals and schematics. Might set you back $50-70.

There are ways to get that radio/mic that you have there working together. But it will involve a schematic and a DVM meter to figure out the pinout for that mic and radio. Not something a beginner might do; but not impossible either.

There may be a member here or two that might have info on that radio . . . stay tuned . . .

Lol I'm so desperate to get a schematic of the mic pin outs I will literally pay some money for some pinouts I'm that desperate.
I don't actually have the mic yet but I will soon I'm sorry I mislead you guys that I have it.But I mainly would like to know how the pinouts work so I can make my own wire connectors to get this mic work.Thanks I have experience with finding out pinouts but this is different and I don't have 50 dollars for the mic yet.And I have only 38 dollars so far and I need to know how it works before purchasing the mic.

Bob Heil starts at about 24:45 on the #235 HAM NATION program on YOU TUBE.

There seems to be a misunderstanding here,

The panasonic he has is a car stereo with PA function, the mic is a cb power mic ,
it looks like a pama or any number of other cheap power mics available with whatever name you want on them,

From what's been said he wants to use the mic with the pa function of the stereo,

finding the pinout of the mic is easy with a multimeter for anybody with prior experience of mics & multimeters using ohms or continuity function to find what wire switches to what in rx & tx,

To find mic audio out use AC millivolts with the meter connected to shield,
probe the other wires while whistling with the mic keyed and look for a reading something like15-50mv that drops when you stop whistling,

There is no info on how its hooked to the stereo in the user manual.,

Here is a link to a Panasonic RJ3600 CB radio from that era that may have similar mic pin outs. it should show them in the schematic attched. The mic configuration is "4 pin" on the Panasonic solid state radios, but it is not Cobra. Is the radio you are trying to match a mic to 4 pin?

I have a similar model base station the Panasonic RJ-3660 which is really cool. It is 40 CH AM with a separate receiver built in for the Public Safety Band. It works and sounds very good on air
