How do i program a motorola GP3188


The Motorola GP3188 is programmable using Motorola CPS software, cable and RIB (radio interface box). The software is proprietary to Motorola and can only be obtained by authorized dealers and other qualifying entities such as Municipalities and/or large companies. The simplest method to get your radios programmed would be to visit your local Motorola dealer or send them to a service center via UPS/FedEx/etc

Best regards.

Hi would you have a circuit diagram for a microphone for a smx4150 mobile 2 way radio?


It's 3 wires, very simple, Ground, Key and Mic Element. Short 2 until u hear the xmit go on, then touch any to the case, that is the "key" the other is the ground.

The remaining one is the mic relative to ground and u can draw u'r own schematic.... Best regards.... MarSay Group

My T5530 don't transmit audio to another radio, you can hear the.


good am, if no audio, try to check the microphone if its ok? , if not, just change, if its ok, try the PTT maybe the switch is busted or need cleaning, most cases is the need to clean due to dust and moisture. just spray contact cleaning fluid. - DU7UV

Wiring diagram for accessory plug needed.


I am looking for the same wiring diagram. The headset Moto sells is a single earpiece with microphone, so how does that end up being a stereo connection Neto? Just curious how, or is there also a full headset with microphone? ( I dont' know, just asking)

Would this be a 4 ring TRS connector? Sleeve = ground, then left, right, and the tip as the microphone??

Walky talky


A walkie talky as we called them, back when we were younger - and hell we probably still do in some respects, hence the fact my friend still refers to her cordless phone as a "walkie talky" and the principals haven't changed that much.

The common old Walkie Talky or CB radio use what we call a half duplex, that means only one person can talk at a time. We are talking and listening on the same channel.

Cell phones are full duplex, meaning two way conversation, and this is simply listening on one channel whilst talking on another, so the basic principal is basically the same, just a little more sophisticated.

Walkie-talkie typically has one channel
CB radio has 40 channels.
Cell phone
can communicate on 1,664 channels or more!

I have included a link to a circuit diagram.

There is also two links below, building the transmitter & receiver.
