Handheld Mic w/ PTT for BITX40

 

I bought a uniden microphone from Amazon. ?It was listed as an electret microphone. ?I also bought the 4 pin panel mount adapter. ?All wired up, it works great and I get great audio reports.

Can you share the item numbers of those items please? It's been a day or two since a bought something on Amazon and I'm sure they are wondering what has happened. Thanks

I bought this mic from Amazon for $7 and wired it up to a cat 5 connector. It has the same type of electret microphone that comes with the kit. I drilled a bigger hole for the mic as the one in the case seemed closed.?Just 4 wires, ground, mic+, ptt and speaker. That leaves me 4 more wires for expansion. Thinking maybe serial or tune for digi modes.

black = speaker, green = ground, red = mic+ and white = ptt
 

Have you gotten this to work?? I am curious to how it was wired up to the board.? I wasn't able to get my similar speaker mic to work due to a common ground.
 

My mic also uses a common ground. I checked the grounds from mic, ptt and speaker on the bitx, they all seem to be the same at least at dc. Schematic seems to show the same.

I connected the ground from the mic on the bitx to the cat5 connector. All the others ptt, mic and speaker share that ground. So far it seems to work fine.
 

There is a thread here that speaks of this.

I used an Icom HM36 hand mic and replaced the bitx40 with the 8-pin chassis mount connector. and wired up the mic and PTT. It works great. Lots of contacts and good audio reports.?

I just saw this reply, sorry it took so long to reply - it is a Uniden BC645. ?

HI Ryan,
How did this go with the HM36 mic? I bought the same one along with the 8 pin chassis mount. Do you have any advise or wiring diagrams for this?

Thanks

Pins 1, 7, 6, 5 are all that needs connecting, I too use the HM-36.

I really should have updated this thread. I have gone a different direction with the mic. I built one from scratch, and it's worked out nicely. I used 8 pin mic connectors because I got 5 of them for $6 on Amazon. I've detailed my homebrewed solution here:

Almost the same here, loads of spare connectors from previous projects, and a spare microphone.
Result... no outlay for new bits.

More to spend on strip board and knobs etc.
