I have a few ideas on this. I think when you key up something is shorting to ground or drawing down the power supply enough that the logic (ie the control circuts) shutdown. that being the case I suggest checking the mike for shorts then the the relay that toggles between transmit and receive and if thats not it. I suspect the power supply is failing. I wish there was a simple solution however as I see it your going to need a meter (DMM) and the schematic.

I found this link hope it helps you.

good luck

Cannot transmitt

The Icom 756 Pro is a very expensive radio. If you bought one and it's not transmitting I really recommend taking it back. It could be anything from the mic, power supply, final transistors, board, anything really. It's going to need to be scoped and looked at in person.

How do I get an icom ic f21 radio that sends a signal to another one receive from another one?

Relays are complicated.. expecially in the same band... but if you have two transceivers which do not interfere with each other, then a relay unit can be made by building a 'carrier detect circuit and relay output' to control the TX/RX of each rig and correctly adjusting the audio levels fed to each.....

How do u turn up a galaxy dx55v.

Hi, my name is John. Welcome to FixYa. Take off the cover, with the circuit side down, take a plastic tuning tool, you can get one at your local electronics store. turn your channel select to midway of the band. make sure your modulation is turned off. Key your mic and tune VR13 to the Maximum on the watt meter. this is for the power. Next, locate VR14 turn the modulation up, and say ahhhhhhhhh, repeat if needed. Thanks for choosing FixYa....John

I am to trasmitt and receive while ignition key is off but when i turn key on i still am able to transmitt but i receive a lot of stastic. I have replaced the antenna and co ax and redone the ground.

Hi, my name is John. That noise you hear is probably coming from switch,such as ,seat belt warning,door,light, key switch , exc. Try running your CB wire strait to the battery, and see if it stops. If not, Radio Shack sells a noise limiter that goes in line with your connection, don't know how much. Do you have your noise limiter or noise blanker switch on the radio?...hope this was very helpful....

Receiver works fine, but nothing out mike, either hailer or transmitter functions. How do I troubleshoot the mic?

make sure that you havent pulled one of the wires loose inside.. it is pretty easy to do.. I did it myself and didnt realize it until i had the same problem.. check where the mic. plugs into the radio first, if that is okay then it may be in your mic itself.. what kind of mic do you have it hooked up to
