Question about Motorola Mag One BPR40 Two Way Radio

1 Answer

My BPR40 transmits to one radio but can't respond ?

I have three radios. One recieves from the other two, but cannot send to the other two. The other two cannot receive. Any suggestions. I am about to clone them to the other radios we have, but don't want to mess something up.

Check your PL/DPL settings among the radios. You may not have them programmed the same as one another. PL (aka private line) blocks out other users who do not have the same code as one another. Your radio which receives could be set with no PL code and it receives and hears every thing, so it would hear the other two, but not talk to them if they have a PL code setting.

Another way to check this is typically the dealer who programmed them will have the side button directly under the PTT programmed for Monitor. If you press this button a short press you should temporarily go into "open squelch" and you would be able to hear everything on your frequency. Try pressing this button on one of your "two" radios and see if they can hear the "one" radio. If so, you know it is a programming issue. (provided the button is programmed to Monitor). If pressing the Monitor button does not allow temporary communication, you have another issue.

If the green light on the radio seems to come on and stay on continuously, the radio is in need of repair. (Average flat rate repair on tehese BPR40s are around $79 currently at many repair centers.)

Best regards.

SOURCE: My magone BPR40 radio isn't sending when PTT

A couple of thoughts:
1) Check the mic hole and see if it is covered or clogged with debris.
2) Does your PTT button seem hard or the opposite, mushy? You could have an internal PTT issue. The PTT is a common failure part on 2-way radios. Feel around for the 'sweet' spot and see if you can make a simple or partial transmission, or if it will even momentarily open up the receiver on the other unit. If so, your radio is in need of repair. It would likely need a new internal PTT. (At most repair centers where the BPR40 is repaired the flat rate repair currently are around $69 for the BPR40)
3) Has any reprogramming been recently done on the radio? If so, double check the programming to be sure your PL/DPL code is set the same as your other radio.\
4) Check your battery. Trade batteries with the other unit and see if the problem changes. It takes more energy to transmit than to receive.

Best regards.

Motorola BPR 40 will transmit,but not receive through the microphone. Works fine as a handheld


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.

Green light stays on bpr40


If this is after programming your radio needs repaired. We see this when some BPR40s are reprogrammed. Take the radio to your local service center or send to a qualified repair center.

Mt mag one bpr40 uhf 450/470 will receive but will not transmit. green light is on all the time


It probably has "busy channel inhibit" turned on in the menus, and the squelch is open, thus making it think there is a signal on the channel you're trying to use.

Flashing red light on radio where it thinks its recieving. Transmits fine but does not recieve.


Three things come to mind:
1) The radio is receiving, hence the light, but you may have a different PL code than the other radio and it is muting the transmission. Check your programming to be certain both radios are programmed alike. The red light indicates activity on your frequency.
2) Your radio may have a problem with the receive side of the radio or a bad speaker.
3) The transmitting radio may have a problem with transmit. This can be a sign of a bad battery. Swap batteries and see if the problem moves to the other radio. If so, replace the battery. (It takes more energy to transmit than to receive, so loss of transmit is common with a bad battery.)

Mag One Radio - Static


If your BPR40 radios are all about the same age, it could be a sign of your batteries getting old and needing replaced. A bad or weak battery will cause the radio to exhibit static, and then eventually poor or no transmit. Check your battery date code first, it is a 3 digit number on the battery label, followed by a space and then usually a number 1. On the 3-digit code, the first number is the year, the next two the week of the year. 229 would be 2012 the 29th week. Replacement batteries should be available for around $35.

If you feel the battery is not the issue, you may have ONE radio which is causing the problem. Try using all your radios and testing by shutting off just one radio at a time. You may identify the culprit. Motorola offers a one year warranty on the BPR40, after the warranty is done, flat rate repair is typically available for $69.

Third possible cause is some type of interference in your area. If this is the case, your radios may need a PL code programmed into them, if you don't already have one. This will filter out unwanted noise or transmissions. Sidenote: If you've added any new computers or electronic office equipment recently, it may also interfere. Some foreign produced computers will lack the filters required in the USA to prevent interference with communications. Coiling excess cables can be helpful in stopping RF noise.

The second of static at the end of your transmission is called "white tail" and is common in all modern radios. There is a programming feature to eliminate most of the white tail noise, it is called reverse burst. Your radio dealer can reprogram your radios and add this to your radios, or future radios you buy. The trade-off with reverse burst is that you will loose the last of your spoken words if you do not hold your PTT an extra moment, as reverse burst actually transmits back or cuts off the end of a transmission to eliminate the noise. White tail is worse when mixing old model and new model radios together.

We use these radios in a race car.They work fine until you hook up the headset for the spotter to use and it drains down the battery real fast.Brand new batteries.


It is possible the headset you are using is not the one engineered for the radio, and draining the battery. Or this radio is being transmitted on heavily and running down the battery. You might try changing headsets and see if the problem clears up. Not all headsets compatible with other Motorola Radios will work with the BPR40.
