Midland GXT550VP4 communication problems

I received a set of 2-way radios and upon charging them and using them, I got a lot of static from one of the units when I tried to talk into it. i also received the same problem when someone tried to talk to the radio. when i grabbed another radio (different type completely) i had, i was able to communicate fine with one of the 550's radios but the other gave static still. I'm thinking that there might be something wrong with the speakers in one of the units.

Did you use the sub-codes? Where they tested indoors or out?

I have a midland 2 way radio trying to transmit and receive without static

If a handheld radios check your battery and/or antenna. Trade with a known good unit to see if the problem is solved with either. A poor battery can often cause static.

If a mobile radio, check your antenna connections and your antenna and coil. This could be a sign of a poor antenna or antenna set-up.

Best regards.

Trying to get our Motorola (yellow/ black) to communicate with Midland two way radios. They Midland will receive messages from Motorola, but they can not send to it Motorola.

Most likely your CTCSS tone codes are not turned on on the Midland radios. The CTCSS codes are also known as "Privacy Codes" or similar.
They will be from 1 to 38. Your Midland manual will tell how to set the codes on the radios. The Motorolas usually show the selected tone code below the channel number.
Alternately, you may be able to turn off the tone code on the Motorola radio(s) by setting it to "0" or "off". Then you will not need codes turned on on any of your radios and they should all communicate fine.

I purchased a Midland 2 way radio for use in a small library. The series is LXT 110. The problem we are having is with a lot of static and other voices coming in. We have change the channels several times...

This model radio does not have Privacy codes to filter your communications,you should change them for a model with this feature. A radio with this feature you have to choose the channel first then the privacy code in both radios or in all radios that want to communicate with, if any radio that is in the same channel but with a diferent privacy code, will not be heard

I want to communicate from t5720 talkabout to midland lxt303. When I set them to the same channel the talkabot gets out but will not receive unless I press the MON button on the face of the radio

Set your interference eliminator code on the T5720 and the Qt filter both to zero. You have one or both turned on. By setting them to zero you will turn them off. Then your radios should work together.

Midland rechargeable battery packs won't recharge and vibrate

You might contact Midland Radio Corp to see if they have a fix for your problem. If I had to give an educated guess I would say the batteries need jump started (which sometimes happens when they are new and too low of charge; or there is a problem where they contact the charger and they are not receiving a full charge; or they are defective. I am sure the factory would be happy to assist you in solving the issue.

Keewood Protalk 2 way radio xls receives , but doesn't transmit

Hello jf1111,

It could be a low battery. Does the screen go completely blank when you attempt to transmit? Two way radios draw a lot more power when transmitting then when receiving so a low battery might cause the radio to cut out when you press the Push-to-Talk and then the radios might appear to turn back on when you release the PTT. If this behavior persists even after charging the battery then the battery or charger (or both) might be defective.

If the battery isn't the issue then the radio could be programmed incorrectly. Does the problem occur on all channels or just one? The Kenwood ProTalk requires dealer programming with a software kit to set the frequencies for each channel. A channel that is programmed for an out of bounds frequencies would generate an error when the PTT is pressed. You might need to have the programming checked out by your local Kenwood Two-Way radio shop.

Best Regards,
"Go Ahead. Use Us."

Motorola T5725 won't work

I have T5720s - both have the same settings (channel 1), both are charged, but they won't communicate. They beep when you push the "talk" button, but you don't hear anything on the second radio.

Any ideas?

One radio has to be set on channel 3 other on channel 18

Hi, One way this would be possible is if you have set offset/duplex operation. My understanding however is that this feature is not normally available for this model. Normally Ch3 is 462.6125 and Ch18 is 462.6250, this can either mean that one of the radio has drifted down (frequency) or the other radio up. Since both are still operational albeit the disparity in frequency, what is probably needed is a simple calibration/adjustment of the PLL/VCO's trim capacitor. Of course a frequency counter & a dummy load wattmeter is needed to perform this. I also understand that FCC requires that you be licensed to be able to adjust/calibrate. Hope this be of some help/idea. Post back should you need additional information. Good luck and kind regards.
