You may have one of three problems: Your audio accessory jack is bad, you are using the wrong mic for the radio, or your mic is bad. Try the mic on a known good BPR40 and if it test good, if so, your BPR40 with the problem needs a new audio accessory jack. (Repair is available for this model.) We have found the BPR40 will only work properly with the remote speaker mic designed for it, despite some other Motorola mics appearing to fit the jack. Construction grade mic PMMN4013 is a good option, as is the lightweight PMMN4077.

SOURCE: my customer has 6 motorola max trac vhf radios.

If this is a new install, it is likely noise from the vehicles electrical system scrambling the processor of the radio. Put a filter on the power leads and check your install.

SOURCE: Can Receive but not Transmit

1) Double check your interference code eliminator and the Qt filter. Make certain they are all set identical.

2) If you are still having trouble, shut off the Qt filter.

3) Then if you still have trouble shut off the code. (Off is sometimes "zero" or "n" for no.)

4) If the above steps do not help you have either a defective radio, or a bad battery. Switch the batteries out of the working units to the non-working and see if the problem switches to the other units. If so, replace the battery packs. (Note: it takes more battery power to transmit, so the problem would first show up in the transmit area.)

Best regards.

I have the AKG wms 40 dual mini mic set with two wireless mics. When mic on ch 2 is in the off position, I get lots of static. Works perfectly fine when on. What do you think is the issue?


Channel 2 mic's receiver needs the Squelch adjusted. The squelch control mutes the receiver so that when the transmitter stops transmitting, erroneous noises are not picked up and amplified.

Have you tried receiving with a EARPHONE? The speakers in these units are VERY poor and do fail easily.

IF the earphone works(!) try a external SPEAKER/MIKE instead of trying to find and install a replacement speaker!

Shure wireless UHF microphone


Make sure the microphone and the receiver are still broadcasting/receiving on the same channel.
Check that all of the appropriate connections are right from the receiver to the mixing board are connected as well.
I hope this helps!

Maxon Model MCB10A


In order to test this unit you will need a power meter with a dummy load. connect the power meter and turn on the unit, key the microphone and look at the power meter it should have a reading of < 4 watts PEP unmodulated and = 4 watts PEP modulated. If you do not have this reading the RF transmitter in the CB might be malfunctioning. You will need a RF generator, a power meter with dummy load, oscilloscope and a multimeter to troubleshoot this problem with. If you do not have or do not know what this equipment is or how it works, please take your unit to a CB repair shop. Thank you, Shuttle83
