While there might be a multitude of answers to this question. The first would be the radio is in need of repair, or not programmed correctly.

To troubleshoot: Unlock your keypad lock, then reprogram your radios to the following settings. (Check function after each change)
1) Shut off the Interference Eliminator (set to zero).
2) Turn off the Qt filter.
3) Vox setting to off.
By shutting off all the "bells and whistles" of the radio, you will take it back to being just simply on a frequency. If your radios do not communicate with one another then, or with your friend's radios, you have radio which is failing to operate.
If the radios do work in this simple mode. One by one add the special features back until you discover the culprit.

Not familiar with this particular radio but it should have an eliminator code. Try setting an eliminator code on both radios, ( they must use the same code on each channel) if you want to talk between the two. If there is a "MON" ( montior ) button, try pressing and holding it in until you hear a confirmation beep.
Hope this helps you.

its the problem of the frequency range its getting blocked at particular location.these can be solved by two options
1)first try changing the location of the unit from one corner to another corner.that should help to catch the frequency again if its getting blocked at particular location.this happens many times.but if changing the locan does not make any difference.then
2) get checked that the antenna of the unit is not catching the required frequency for the unit.so change the antenna also connect this external antenna as mentioned 50 ω (it comes wioth SMA Connector) that helps in catchinf the frequency.
you will get this at radio shack website. this will help.
also in the unit there is a component which controls the frequency called microprocessor if that goes weak the unit slowly slowly stops receving the accurate signals and only the noise comes.so the micro processor in located internally in the left side.its a green and black colour mini chip circuit board.many times opening the unit and removing and cleaning the microprocessor and refitting it solves the problem but this is 50 --- 50 chance.
this all has to be checked what mentioned.
thank you for using fixya.
