Hi

I had a problem with my 910 auto-tune swhen I first purchased. I've reproduced below a response to a previous question on HF's.

Post ID 7223

I have a Barrett 950, with a 910 auto tune antenna. I was going to stick it on the back of my Defender, but was also advised that its ability to function at an optimal level "may" suffer. Given HF is not an exact science, and the difficulty in quantifying the impact it would have if it was rear mounted, I went the bullbar option.

That opens another can-of-worms, the legaility of it being mounted on the bullbar. I am in NSW, and as far as I can see it is not a problem, providing nothing protrudes in front of the bar. Then someone pointed out that it "could" be argued it obstructs the vision of the driver. In the end I simply took the view that it is a safety thing for me, and if I'm in an emergency situation I want to give it the best chance of working as efficiently as it can.

As a footnote, when I purchased my unit, the 910 antenna was failing to autotune on a regular basis. Sometimes after only 2/3 goes at trying to get through on a frequency. After trouble shooting (the whole system) with a HF technician we replaced the antenna with another one (from the same batch), and it still failed. Finally we tried one that was not within the serial number range of the first two, and it hasn't failed since.

Barret have not offered an explanation, however I wonder if there are other antennas out there, from the same batch as the first two I tried, that may be faulty?

There's no point in playing around in there yourself - its full of electronic gizmos and wheelygigs - seen it myself - looks like the inside of a TV set ! Mine was on the blink too at one stage - had moisture in it - very fine crack at the top where the threaded bolt emerges - due to wear and tear - temperature fluctuations sucks the moisture in.... might be something else too - mailed mine back to the factory via Aust Post - fixed it up nicely - good people to deal with in my view. Unless you found something hanging off and could simply re-attach it, might pay to send it back - if you have a dud circuit and keep poking that energy into it, you might cook the lot.Why I am here looking at this screen ?

THANKS VERY MUCH FOR THE SOUND ADVISE. PRESUME THAT YOU WENT DIRECT TO BARRETT REGARDS PETER
