Thank you for explaining that in a way that is easy to understand. So it sounds like I'll be in business with that D104m6b with either radio. So what do you think the likelihood is that rewiring that mic will fix all the issues that the smokey is currently experiencing? Well minus the meter...

Good Morning Guitar_199! Nope all info is welcome and any info I may already have is just confirmation that it is correct. I'm in luck because I just so happen to have an Astatic D104m6b mic doing a whole lot of nothing...well besides collecting dust that is. It didn't sound all that great on...

Thank you David. I have an Astatic D104m6b mic. I think this will be my best bet then. It looks like it has 6 wires in it.

So to recap...pun intended...it is operational and receives. The meter acts funky on receive and actually back dips as opposed to moving forward when someone is modulating (small potatoes at this point). Now to the PA. A high pitched oscillating whine or hum can be heard through a speaker but no...

I'll be around and I appreciate all of the help. Enjoy that nap! You weren't lying when you said tiny! Pure luck that I found it. I'll check the PA. Forgot to do that.

I appreciate the reply. I'll clean that one up. At the moment I've got her calling working a stupid piece of solder wick got left behind and was bridging a cap. Rookie mistake. So I have receive and can transmit a carrier but no modulation. I believe that is probably an issue related yo mic...

The meter seems to be inoperable to a degree. It back swings when receiving as opposed to moving forward. Small potatoes. Now I just need to troubleshoot the no modulation or figure out a way to wire an astatic up to it.

Holey $hit it's working! There was a tiny piece of wick left connecting two points on one cap! It's now transmitting a carrier but no modulation.

Two different issues. You asked about the solder connections on the board and that was what I was referencing. There are only 4 pins for the mic plug on the radio. Cobra and midlands both use 4 wires for 4 pins but if you look at that astatic wiring info it references 5 wires (4+shield) for the...

So it looks like 2-3 does the receive and 2-4 does transmit because shuts the green meter light off. The red one does not activate though. It mimics the adapter with mic. The volume coming from the speaker is still muted. There's definitely an issue with power flow on the board because when I...

What I meant by adapter was I had assumed that the mic wiring was for a Midland since the cobra plug does nothing when plugged in. With a mic with a cobra plug plugged into the Midland adapter you would get receive and be able to transmit a carrier but with no modulation. In order to get any...

Also if the mic adapter combo I have is removed you lose what little sound is present from the speaker. Keying the mic mutes what little sound is present in the speaker but no click or pop. I think everything was operational before I touched it and it was a mic issue all along. Now I just need...

Also there is a pop from the speaker when the channel selector is rotated of the cb/pa switch is cycled.

I had to duck out really quick to pick up my son so I didn't have an opportunity to look at that spot but I will as soon as I get back. I have several other radios that are operational ( Yaesu Ft-891, Uniden 78, cobra 50wxst) and a Galaxy 959 that has issues...possibly a blown final. Right now...

You have been a huge, huge help! Amazing investigative work.

I have to duck out for a bit and go pick up the kid but I will as soon as I get back. That was untouched by me but not to say board flex from me working on the board didn't dislodge something. Not to mention I had an initial problem prior to me potentially creating more.

You were right! It's in cb-104. I was clicking on the different photos from ebay sellers and ironically one took a picture of it!

I appreciate the attempt regardless of the results.

Lol fair enough. I can fully appreciate that! I'll have to poor over it under the mag. I'm sure it's something I screwed up. I just hope it isn't something irreparable.
