Hello scooter 34 1,

Are you able to get a new mic for your radio? Because I really think the problem is in the mic. Here is a test buy a cheap replacement mic that can be used with your unit and swap it out with your current mic. 9 time out of 10 this will solve the problem. If not the problem may be with the sensor switch inside of the unit itself, the sensor switch detects when the mic is activated, it avoids the galvanic response of the metallic switch in the mic. The switch could have malfunctioned. However I repeat, that I believe the mic has malfunctioned.

I hope this helps,

Does Motoroloa make a mic with controls in the head for the MCS2000?

It's very unusual to find a commercial radio with channel buttons on the microphone, however, with a bit of ingenuity, you should be able to do this. You need to connect two additional wires to the mic connector on the radio and replace the microphone with one that has the buttons. Connect each od these wires to the UP and DOWN buttons on the front panel. You will have to locate two pins on the mic connector that aren't being used. Usually there are a few available. You may have to disconnect two that are being used for the programming function if you don't have any available. This will have to be changed back to the programming function if you want to program the radio again. Connect the two wires in the microphone head to the up and down switches, and there you go. The other pin on the switches most likely connect to ground. You may have to get another mic cord if the one on your present microphone doesn't have any spares.

Just got a Galaxy DX 2547. Barefoot works GREAT. Problem: When connecting to my linear (Texas Star 667V) rig fires up AOK on AM but on SSB it has issues driving the amp. SWR is OK Radio SSB output ~...

Have you tried turning the mic gain up,and not knowing Texas star model numbers,is it a mobile linear,if so,do you have a sufficient power supply?Just some thoughts off top of my head.

After keying antena lite stays on have to turn radio off to clear

Make sure your antenna is tuned properly. The light comes on when the SWR is too high. This damages the final transmission transistor. You can blow the transmit in the radio.

If you need to tune your antenna and do not know now, go here and follow the instructions...

tune SWR

there could already be some damage to the final transistor already, it may be why the light stays on. Tune the antenna according to the article and then if the light stays on again, there may be something wrong with the radio, or the warning light is not adjusted correctly.

If your swr is okay, then turn vr6 all the way down so the light does not come on.

I can't xmit or receive on CB channels: Wx channels come in OK. I had a bad WalMart Special mobile antenna which shorted out because of corrosion. Now have a Diesel 15 inch mobile with tunable SWR tip....

If try another mic and see if problem is still
there then you have half of the problem,the
TX an RX all go through the mic if mic good
you will have to go inside of the unit.
Good Luck
