After i press the ptt button there is static - Motorola Walkie Talkie 2-Way Radio

If you can do minor soldering, you may be able to fix the radio. They have no parts available, so they are considered "junk" when they break. But if you do the following, you may be able to repair it: open radio, unscrew the housing and pull it apart. Take the circuit board and look for corrosion, it often looks greenish or white. If the radio has a lot, there is water damage. You may still be able to fix it. You've gone this far! Use a Q Tip dipped in rubbing alcohol and remove as much corrosion as you can. Let it dry. Take your soldering gun and lightly resolder each spot on the circuit board. Touch the tip, as soon as the solder turns liquid, remove it! I have fixedhundreds of radios and cell phones by doing this. But it may not work. It just takes your labor! Good luck!

I would like to help, but your question doesn't make any sense what-so-ever. Could you please explain it better?

This problem is typically caused by small component behind the PTT button being cracked or broken. The RDX series radios respond best if the user presses the PTT button in the center versus the top or bottom sections of the button. Once the button becomes hard to press it is best to get the radio repaired. Commonly if the radio remains in use the PTT issue will get worse as the internal PTT component is pressed harder, pushing it further away from the outside button and eventually loosening it from the component board.

The MU21CV radio is user programmable. Hold in the PTT button while turning on the radio. It will announce the frequency. Use the PTT button to count it up to the frequency you desire. Press the smaller monitor button to lock in your freq. Then the radio will announce the code number. Once again using the PTT button count it up to your desired code or the word OFF if you are not wanting a code. Then press the monitor button to lock in the code. At this point you can turn off the radio and turn it back on normally (without holding in the PTT). Your radios should be programmed to match one another. If you are still having trouble you may have a radio which needs repair or a bad/low battery.
Best regards.

Hi,

The question I would ask is:

How close are the two radios to each other when you contact from one to the other?

A distance between the two radios of about 10-15ft, preferably more is desirable to achieve audible results, having the closer than 10ft, causes one to cancel the other out, so you either hear static, feedback or nothing.

Try 15ft of more distance between radios and see what happens.

Pls feel free to post the results here on the two way radio forum, as I'm interested to find out what happens.

Cheers, Peter@FixYa Team

The SP21 is PTT programmable.
1) Hold in the PTT while turning on the radio. Let go when the female voice begins to speak. It will announce the frequency number. You can use the PTT to walk through the 35 to 40 frequencies available. Then when you have reached your desired frequency. Press the MONITOR button to lock it in. (small button on the PTT).
2) Then your radio will announce the PL code. Using the same method of pressing the PTT you can walk yourself through the 38 possible PL codes. Press the MONITOR button to lock in your preferred code.

To answer your question concerning 12.5k to 25k selection. You should at this point in time be changing to 12.5k (narrowband). All VHF and UHF users are required to move to narrowband by Jan. 2013.

In the VHF SP21 frequencies 1-16 are 25k, and 17-37 are 12.5k.

In the UHF SP21 frequencies 1-16 are 25k, and 17-40 are 12.5k.

Best regards.

The PTT button is one of the common failure parts. It is replaceable, but best done by an experienced repair center.

The following things can happen over time:
1) The internal PTT switch can wear out from frequent usage.
2) The user begins to press harder to get the PTT to work, bending the PTT switch further away from the external button the user is pressing.
3) Plastic diaphram, if any present, gets broken in half, and the external PTT switch doesn't work anymore.

Several companies offer flat rate repair on this style unit for around $85.

Best regards.

The flashing light can be an indication there is activity on the frequency the radio is set to. Pressing the monitor button should give you the white noise (static) sound, so this function is working correctly. This also tells us your speaker is working fine, as well as your volume. The typical reason you cannot go into programming mode (when you hold the PTT in while turning on the radio and hear the female voice announce your frequency) is a bad or moved internal PTT switch. This typically happens over time as a user presses ever harder on the PTT to communicate. However, this does not explain why you are not receiving. This could simply be a result of an incorrect PL code in conjunction with the bad PTT. If you have a frame removal tool, you can extract the component board and physically look at the internal PTT. You can then hold in the very small button and program the radio to the frequency/PL you desire. If you are needing the radio repaired, you can get this style unit repaired for around $69 flat rate

Contact a service center in your own country.
turn the squelch button down.

Here's your help:

Read out one of your radios by holding in the PTT while turning on the radio. It will announce the Frequency. Then press the Monitor Button and it will announce the code. Press the monitor button again, to leave the code set, and then shut off the radio.

On the second radio: Hold in the PTT button while turning on the radio. It will announce the frequency. Use the PTT to get to the number you need to match the first radio. To lock in the setting press the smaller button, known as the Monitor Button.

This will make the radio announce the private line code number. Using the PTT set this to the code number of your first radio, then press the Monitor Button to lock in your code.

Shut the radio off and turn it on again to begin use.
