Uhf not operating...at all

They only cost a few bob , So get a new one , better then trying to figure what's wrong, and you will get warranty.
Its my motto not to travel with faulty gear..

Take it to the "doctor". Sounds like something was failing and it now has broken.

Get it to a shop etc. Is it under warranty. If under warranty the less you touch the better the chance of them honouring the warranty. Start mucking about by opening it up and you may void any warranty.

Mike ..could it be there's nothing wrong with your TX, just that no-one wants to talk to you !!? (No need to copy that)

"What else should i be looking for?" A GME or ICOM.

Not very helpful guys...

Ron, if it is something like a fuse then id be stupid to go and buy a new one without investigating the problem first, im not 'on the road' at the moment so its not that important.

Vk1dx, i think i will take it in to someone who might know what they're talking about as some of the people on here are just out to stir chit, Dion im pointing at you, i ask a simple question and you give a silly answer

G'day Mike GU,

After some of those wonderful responses above, I'm surprised you're not pulling your hair out!!!

Can I ask, how have you got it wired up? I always wire radios up so they are not dependant upon the ignition or accessories being on. That way you can use the radio regardless of the key being in the ignition.

So, if you have it wired up like that, then you need to check that there is power getting to the plug at the back of the radio. I'm assuming here that your radio has a short (about 6") dual cable with a plug that mates-up to a similar fitting that brings the power to the unit.

You need to separate this plug into it's 2 halves and use either a multi meter of test probe light to ensure you have not only a good power supply BUT ALSO a good earth connection. If you check this and there is both + and - at the supply end of the plug, then you can at least be sure it's not the wiring going to the radio.

THEN it might be time to take it to the radio doctor, but check to see if there are any other fuses on the back of the radio first up.

Now, if your radio is only available for use with the ignition set to either accessories or with motor running, then you need to do the above check-up with the key set to the necessary position.

Hope this helps.....
