Uniden vhf Recieves fine but no tx? Tx light comes on, and it sounds like it is working, but noone can hear me?

Hi,

Initially, pls check/clean your antenna, mount, coaxial cable, RF connector, power leads, grounding straps.

Based on your post description, a couple of ideas:
1. Since you receive OK, chances are the antenna/cable is good. You verify though with an SWR meter;
2. Since TX light comes on, looks like the mic, PTT and coiled cord are all OK;
3. All else works but no one can hear you, you have no power output. Use an RF wattmeter with dummy load to verify that you are pushing at least 25 watts. In the absence of a power meter, the SWR would also do or even an indication of a significant current flow to the radio ( use an inline ammeter) would indicate power.
As you will note, some specialized instruments are needed. Perhaps your best bet would be to seek the services of a qualified communications technician. TMore often it is the finals or power pack that fails resulting in no TX. In some cases, it is either the RF diode or the power regulator that causes no TX. It may also be worth your while to do a full check over of your antenna system.

Hope this be of some help. Pls post back how things turns up or should you need additional information.

Good luck and kind regards.
