uhf crap sending signal

a DAQ......You don't drive at Mach 1 with all the windows wound down and the rock box cranked up? LOL. Sorry, couldn't resist.

no the young fella may but not me :)

is it just the cars behind or infront aswell sounds strange? if you cant be herd then it must be on your side my uhf can pick up other ppl even with out an antenna connected but doubt it will send not that ive tried sending without one. the antenna must be faulty or coax not fitted correctly . check the coax cable comeing from the antenna also as ive had some ass pull the cord out of one of my antennas at a train station ive since fitted them in copper pipe and fastend it to the bull bar.

Ok read all the above before commenting.

Firstly is a shop bought set? Matching mic to radio?

Do you have another aerial(AM CB, Sat Phone) right next to UHF aerial with that set also turne on?

Have you made sure earth on power feed lines has not come loose, or the earth on aerial?

Is the mic rattling when being used?If so it could be the mic needs replacing.

And just check aerial and mic plugs are tight on set.

Hi, suggest you check your electrical connections - It's not that unusual for a radio to receive but not transmit - transmitting takes more power than receiving - so a poor connection or earth may allow you to receive but not transmit . Also, I think, pushing the speak button, ie transmitting. without an aerial connection can damage your radio - check the manual . Hope this helps !
cheers

Is it an old radio or newer one? Distance shouldnt be a problem, and where the antenna is mounted is ok. If its receiving ok but not transmitting properly could be a problem in the transmit part of the radio.

If you are breaking through to them but all they can hear is interference would mean you have enough power to reach them but they can't understand because of interference. I would try another mic, if you can borrow someones and test.
Simple method of ilimination would be to try a mic and if it is no it then try and swap the radio(if you can). At least you will know if its the radio or mic or coax/aerial
What sort of interference is it?

I had the same problem the other day. I turned the UHF on and put it on scan. I tried to transmit, with the radio automatically returning to Ch 40 and, nothing. I unscrewed the mike, then put it back in, and pressed the button, and it worked. Not sure why, because I haven't touched anything previously, but it worked. Try that.

Sure it isn't a simplex duplex error lol

At that distance they probably hear you bleeding through .

I had the same issue with my new GME and even went back to the store to check it all was wired up correctly and everything seemed ok, It turns out it was a dodgy sender unit inside that had carked it.

It could be heard up to 100m away but after that it was dead.

The unit was an ex display and am not sure if it was powered up with no aerial attached and the mic used, as we all know you cannot transmit without an aerial attached as it can damage uhf.

It was sent back to GME and all was fixed.
