I have a pair of talkabouts fv700's they will receive but I cannot transmit

Take the radios back to a very basic setting with all special features turned off. If the radios have a Qt filter check to see it is turned off, and set your Code to zero (off) on both units. Also, check to see your battery is good in both units. Trade the battery with a known good radio to see if the problem moves to the other radio, is a simple test.

Hi have a nice day!

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

defect ptt buttom

Not certain what model radio you are using to transmit, it is possible your radio has a Qt filter. If so, set it to zero. If this does not solve the problem, try setting your Code to zero also.

Best regards.

motorola has extra security and will not operate with other radio makes very well. It must be locking out the uniden radios.

Moisture and oxidation on the circuit board will create noise during transmission. You may remove the cover and wipe around microphone and the circuit.Ensure its dry. Cover it back and test.

had the same problem...took out nimh...replaced with triple A...works great!!
Thank you!!

Hello snorker,

It could be battery / power issue. Two-way radios draw much more power when transmitting then receiving. If the batteries are weak the radio might work perfectly fine on receive and then cut-out when you depress the Push-To-Talk.

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.
