Having problesm.. Hope its in the settings

Radar in particular can be very difficult to shield against because the wavelength is so short that it will fit through small openings. If you've ever watched video crews on military ships the high powered radar gets into the audio signal with ease and even sometimes breaks up the video feed. You can hear the radar dish rotate in some cases and as it comes around there is a high pitched whine in the audio, and the video loses sync for a second. Then it goes away for a couple of seconds and returns as the dish comes back around.

Very true. I have had radar interference on poorly shielded tv's/radios, etc with it being as you described. Plus, there is an airbase not too far away that we can pick up broadcasts from planes to the tower when they are coming in for landing on occasion if we are watching a local tv station over antenna. Even the socalled digital broadcasts.
However, the interference from any of those are not usually constant throughout the day (or evening/night) and would affect more than just this detector. As I have owned and used 4 to 5 other detectors in this area for the last couple of years, to include Excaliber II, Xterra 705, AT Pro, Etrac, and one other that I quite frankly cant remember at the moment, and not experienced such interference, or at least not on any consistant basis, then I doubt that electrical interference would be a contant problem for this particular detector unless there is circuitry in this model that makes it susceptable. And since changing frequencies is normally fairly effective at reducing most interefence, then that should be easily resolved. Usually...not always.

However since, in this case, it has been resolved that the problem was/is a bad cable which when pushed or prodded caused an increase and/or lessening of the noise depending on position, then it was quite apparent at that point. Now that being said, with the cable being bad, this could have also resulted in the shielding being ineffective on the cable making it more susceptable to outside electrical interference. So, it could have been a combination of factors. I have seen many such problems in cables over the years from having built thousands of them in the past. Twisted pair cableing is some of the more problem prone wiring there is. Or was, when I was in the field.

Still in all, a situation like this does make for an interesting discussion. Something for everyone to learn something new.

Hey, did you check your X1 switch to make sure it wasn't mistakingly turned on... Oh Yeah, forgot Minelab didn't allow us that option anymore. Had to say it, as this is still troubling me. HH, Mike

Well, I got my replacement 3030 from my dealer. I tried it out just real quick the day I got it and it worked like it should have. No problems or at least none noted at the time. I didnt get all the beeps, squecks and swawks and all the noise that I got from the original one. I havent had a chance to to really try it out at the beach as it has been so hot and I have been ill the last few days. Docs changed some of my meds and they are kicking my behind. Makes me feel like a guinea pig.

Anyway, the replacement 3030 is great and I am happy. Soon as I can, I am getting out to the beach and find some treasure. Or at least a few coins. Thanks to everyone who responded. Its been great. And shows the quality of folks here on FIND's. Thanks all.
