Two Way Radio Microphone

Headset: two pin
Two way radio: has only 1 pin (it only accepts a special headset set)
But I was thinking that I could unscrew the radio and solder the speaker wire to the one connected the build in speaker and the microphone to the build in mic. Can someone tell me I this will work out?

It depends on the radio. Vehicle radios can be anywhere from 8 ohm to 50 ohm speaker outputs. Handhelds can be from 16 ohm to 600 ohm outputs. Most Motorola handhelds are about 16 ohm outputs to the headset or speaker mics.
Transmit audio is a different story. Many two way radios put DC voltage on the mic line for amplified mic elements. They take close to 1/2 volt audio. Others only take a few millivolts. If your add on mic way overdrives the radio you can try adding resistors in line till it sounds good. 10k ohm or so.
After all that, it's not going to sound very good. Computer mics are made to transmit up to 20khz. Most two way readios only handle 3khz audio and don't sound good if you try to cram high frequency audio down their throats. Computer mics tend to be way too sensitive and pick up a lot of background noise too.

It's kind of an odd thing here. I drive a cab on weekends. In the cab we have a computer that is used to dispatch calls via call center. When we get a call the computer beeps and we have 1 minute to accept before the computer books us off and then I go back to the end of the line (queue).. which really sucks time-wise.

This can be avoided if I am in a convenient store in line or inside my house on a break (eating lunch, feeding pets, bathroom, etc..), with something that alerts me.

What I am really looking for is something that has a speaker and microphone, like a two way radio. Are there two way radio's that can be set like a baby monitor in the cab, so I can hear the beeping on the computer?

I have been looking online, but I'm not seeing anything practical. anyone have any links?

y dont u use a real baby monitor? its easy and cheap, dont u think? no radios no shit. it beeps, u hear it n go.... that sucks man, better leave it that way and dont sorry when u miss a call, its better than to live in a constant stress with no time for a normal lunch... and most of all - during the weekend...

Earpiece design makes hearing easier in noisy or hushed environments. Earpiece fits on the outisde of either ear.
PTT-only with TalkAbout T5100, T5200, and fr50 and fr60 radios
Designed for great sound, even in noisy environments
Boom mic bends for easy positioning. Microphone placement is virtually unlimited.

My wife and I shoot wedding photography together, we want a small radio which we can use to talk back and forth without yelling across the room. We like the small bluetooth headsets that everybody has for their phones, but the battery life of the cell phone is an issue, weddings can last up to +10 hours. The smaller the better, preferably without wires or long protruding microphones. We don't want to scare people, just be able to communicate better. Thanks!
I don't want to carry around a handheld radio. I want to have one little thing on my ear which is the radio.

I would suggest searching through online reviews of what is the best in the market now. I would suggest buying the Trisquare TSX300 or Motorola EM1000. Anyway good luck!

Price: $189.99

Durable, lightweight design. Easy for employees to carry and hold all day, yet built to withstand everyday use
Quickly copy the settings from radio to radio with the use of the optional #56517 (cloning, charging, storage) accessory
Includes Lithium-ion rechargeable battery, drop-in charger, and swivel holster
Keypad lock, audible call tones, VOX--voice activated transmit with select audio accessories (not included)
Requires FCC license. Compatible with Motorola Spirit GT,GT+, and XTN UHF radios.

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?
