Question about Cobra FRS 70 (2 Channels) 2-Way Radio
The radios will not transmit when the call button is pushed or the PTT button. Both radios have been turned on. Both radios are on the same channel. I also tried switching channels.

This radios has a Reference Xtal, dropping the radio, could cause that the xtal goes out of frequency, this means tha the radios has a frequency error and the range of opearatin seems to be reduced or even null. With out knowlegement and equipmente, there is nothing that you can do.

Please don't touch any internal adjustments. It is like a 10 digit combination lock that is set to open. If you start changing the numbers, you will never get it open.
I think the problem is with your tone coded squelch (CTCSS). Your radio channel is like a telephone party line. If your CTCSS is not on, everytime you turn your radio on you will hear anyone on that channel that is close enough to hear.
If you are trying to use these radios for serious communications, that will drive you nuts to hear everybody else talking but not about what you need to hear. To try to mitigate this problem, CTCSS was created. There are 38 different codes. If you for example set your unit to operate on code 11 and your other unit is set to operate on code 12, you could not hear each other.
Now let's add a third unit set to not use CTCSS at all. Neither one of you will be able to hear this third unit but he can hear both of you. Now you set the second unit to code 11 like the first unit. Now you will be able to hear each other. The third unit will still be able to hear both of you but since he is not transmitting code 11, you still can't hear him.
If you are hearing some traffic, it is because they have their CTCSS set to the same code that you are set to. Look in you operators manual for CTCSS Privacy Codes. Set your radios accordingly and I think you will be in business. Let me know if this doesn't take care of you problem.

Sounds like the radio was subjected to electrostatic discharge. If you have your manual, and it describes a way to do a "master reset" on the radio, follow the instructions. This usually involves pushing down on one key while turning the radio on. Otherwise you have to find a licensed dealer for factory service, as there is no way to repair the radio yourself. The use of surface mount technology still confuses many Techs unless they have been to a company's two or three week seminars.
