Comms problem between motorola t5522 and t5720

Try swapping the known good battery out of your working unit and see if that solves the problem. If so, replace the battery pack. If this is not the problem, unfortunately your best option is to replace the one unit. Parts and schematics were never made available for this model.

Best regards.

try by changing its chanel and sub chanel if subchanel is not the same it will recive only.. try it..

CHANNELS DON'T SAME YOU SHOULD USE SAME TALAKABOUT IN TWO WAYS

These are mass produced radios which although serial numbered inside under batterys - it is very unlikely that you will trace an owner. cheap and cheerful radios dont usually attract the effort to register

One further thing to check would be the Qt filter.

If the frequency, code and Qt filter are all set alike, and the radios still do not function together, you likely have a defective radio. The only way to determine if one is bad is to introduce a 3rd radio into the group, and the bad radio will be apparent right away.

You could try eBay, or Motorola's online store http://www.store.motorola.com/mot/en/US/adirect/motorola?cmd=catDisplayStyle&catKey=601700
or you should be able to get a similar unit at your local Walmart. The T5720 has not been produced for a while, but other TalkAbout radios will communicate with your existing radio.

Here is a manual link which says it covers the 5500 through the 5550. http://www.usersmanualguide.com/motorola/2-way_radio/t5500

Hello jayhawkrx,

Check the Continuous Tone Coded Squelch (CTCSS) settings on all the radios. (Note that some manufacturers refer to this feature as a Privacy Code or Quiet Code. The actual name of the feature may vary.) This feature encodes a low-frequency signal on your radio transmission. This signal is below the range of human hearing but can be detected by other radios. When the CTCSS feature is active your radio will ignore any signal that it receives that does not have the proper tone encoded on it.

In order for these radios to communicate, all of the radios need to be on the same channel and have the same CTCSS code programmed or the CTCSS feature must be disabled.

I suspect that CTCSS is activated on one of your radios but not on the other. This would result in the situation you describe.

Also take note that when using different brands / models of radios to communicate with one another that the CTCSS code numbering scheme may not necessarily be the same from radio to radio. For instance, CTCSS code 4 on the Motorola TalkAbout series actually corresponds to code A on the Motorola Sport models.

Best Regards,

Agent Ken
