control head

This is a weird one. APX 6500 with remote o5 head, audio is mute when audio pot is turned all the way down (expected). However, audio doesn't actually show up until the vol pot has been rotated more than expected, and then when audio is present, the volume is way higher than expected. I presumed...

I have a like new Motorola CDM1550 that the Control Head has become unresponsive. It will no longer allow me to use any of the buttons on the control head. The radio powers up fine and broadcasts audio, it will also transmit without any issues. The radio powers on to whatever channel you have in...

I did an experiment with my Yaesu FTM-500D today that was a success. The goal was to see how far the control head could be from the radio body, and to also see how tolerant the link is to what in older telephone parlance would be an open bridge tap. The reason for the bridge tap test is to...

Hi all, I have an XTL2500 with the standard M5 head on it. I have made it to an O5 by flipping the tab around but the flex cable does not match up to fit my APXs connector. Can anyone point me in the right direction for the adapter to get the M5 connectors to work with my APX 7500 connections if...

I have an XTL5000 800MHz that is headless. There are two db25 pin connectors on my radio. Is the XTL5000 capable of working with the W3 head? Has anyone had any success in making this work?

The indicator lights and the backlight on my Motorola PM1500 Control Head do not seem to be working. Any ideas?

I was attempting to see if a control head was functional with a known working radio. I attached the power, remote cable, and ground. When I turned on the radio I saw all the normal LCD options flash and then a PP appeared in the upper left corner of the display. Soon thereafter it shut off. This...

Hello All, My question is a simple one with what I expect to be a complicated answer. Are different styles of Motorola control heads interchangeable? For example If you have a radio with an ID number that indicates a W9 head will a W7, W5 or W4 head work with it? My first reaction was no...

Hi: I bought a couple of these puppies sans control heads and I'm wondering if anyone knows where I could find some. Thanks, Steve KA1ZFY
