Realistic Navaho trc-431 base

most radio shack radios used the 5 DIN jacks, not the 5 pin jacks. not the small jack of course.

 

It is a 5 pin DIN plug. Wired as follows:

1- Shield
2- N/C
3- Transmit
4- Audio
5- Receive

 

Adapters exist but often are loose and not very well suited for rough road conditions. Myself I would find a shop and get a DIN plug installed on the mike. Of course this is a base so the adapter idea may not be a big deal. Search fleabay for one.

 

There are some other CB's that used the Realistic style DIN plugs on the mics. The JC Penney 6204, Cobra 20 plus, Maxon MCB-30, all come to mind.

I can't say I've seen any adapters for the Realistic mic plugs. If you know how to solder, and have a soldering iron, you could always take a typical Cobra mic and solder on a Realistic mic plug.

Or....you could always swap out the TRC-431's mic receptacle to the typical 4 pin Cobra style, if you know what wires (soldered on the rear) are what and to where to solder them to on the new receptacle. I recently did this on a TRC-459 I recently acquired.

You have a license for the HTX-10? Or planning on getting one?

 

I prefer doing the dedicated plug myself but I have a Realistic DIN to Cobra 4 pin adapter I use every so often on my bench. The quality is fairly good. IIRC I think I got it off fleabay. Usually those models have a chassis mount plug with right angle pins soldered to the board. Combined with a thick lip in the plastic faceplate it's a real pain to mount a 4 pin chassis connector and run wires to the board since the nut to hold it cannot be used as the depth required is too great. On more than one ratshack I have had to use epoxy to mount a chassis connector to the front face (in the hole, looked nice but tedious work) and run wires to the board the socket was removed from. Every once in a while someone has a Navajo or something and want all their radios to use the same 4 pin mike. I think I vote for the adapter found on fleabay unless He has a shop near to have the plug changed. If you have good soldering and little parts mechanical skills, changing the plug not too hard. Is why I posted the pin-out info above.

 

Ahh...good deal. I just asked b/c I was hoping you weren't thinking of trying to set the HTX-10 up for CB use...not that I care if you tried, but word is they're a PITA to do. (probably why the Magnum 257 exists lol) Bummer on the TS-2000 I have one and they're nice rigs, albeit pricey. Good luck on the 2 meter rig, good thing is they're common and not as expensive as some of the other rigs, namely the 70 cm ones.
