Microphone For Two Way Radio

Whenever I plug my Microphone/Earphone into the mic slot of my two way radios, it forces that radio in a transmit mode, so rather than waiting for me to push the button to communicate, it constantly transmits my voice. This wouldnt be a problem if it didnt block any incoming signals.

Any ideas how to fix this?
Its not a short, otherwise both radios wouldnt do it

Take it apart and see where the Push to talk circuit is shorting to another circuit and disconnect that.

Pardon me if I sound skeptical about your license, but how did you pass you license exam if you can't estimate the range of this radio?

I'm trying to run a webcam broadcast, and I'd like background music for when I'm talking. Kinda like a DJ on the radio when they do their breaks in the songs. Other than buy an hardware mixer, is there a program out there that will basically let me combine the "What you Hear" and "Microphone" channels into one, to be broadcast through either of them?

I'm not looking for a program that will let me pre-record them together (aka Audacity with two audio layers), as this will be live broadcasts.

Using loud speakers is not an option either, as it would bother the others in the house.

I once had a motorola compatable surveillance ear piece that was a two wire. It had a replaceable speaker that you could switch out where the coil ear piece attached. It also had one wire coming out of the plug part that ran to a belt clip with a ptt button before it slplit into the two wires. In other words it had a BELT clip PTT button as well as the one that was one the microphone clip that ran (at least how i wore it) to the chest.

I have since lost track of it after 4 years and I really really want to get another one, but cannot find anything even close to it online. I DO NOT want one of the wrist or finger 3 wires, they are uncomfortable and difficult to use, (at least for me). Any help would be greatly appreciated.
ok I understand the interface and everything else. I am actually looking to find out the name/model number of a specific ear piece.

It has 2 wires coming out of the plug, both of them go to a belt clip that contains only a ptt button. From there two wires exit and one goes to the ear loop, with a removable/exchangable speaker. The other goes to the lapel mic which contains another ptt button.

I dont know wht i want to suggest to u..
But i just come cross this site:

I have a project where I'm taking two CB Radios, and taking a Y-Splitter and splicing them into one cord to LINE-IN on a computer. The computer has software that can split the RIGHT and LEFT audio channels back into separate CB channels to record the sound. What I have is a constant hum on the LEFT Audio channel, that happens no matter which one or both CB's are plugged in. I've chalked this upto the default LINE-IN input not handling the power coming from the CB's. The Software program suggests I get a better sound card or purchase a microphone pre-amplifier...where can I find the right device to purchase online, and what device would work perfectly for solving this hum issue?

Whenever you are combining two or more audio outputs to one or two (right and left) the best tool to do this and eliminate a lot of issues is a mixer. A small inexpensive mixer would work great for what you are doing.

Of course you would need the right cables to interface the CB's to the mixer and the mixer to the computer. They should all be "off the shelf" cables.

Here is a great small mixer that would do the trick:
