[QUOTE="Reg Wilson, post: 523110, member: 10941"] Dave63, I don't understand why you would be running your QED at TH-A at 001. This just makes no sense at all to me, plus you say you have intermittent noise all the time. Something is not right. Have you tried a different coil? Your QED should have the latest DSM ground balance system where the factory default is set at 150. This is wrong and confusing, as the average GB in Central Victoria is well above that at 220 or even more. Start off by getting a decent GB with your Bias just audible; then set your THS-A at about 60. This will increase your threshold, so go back to Bias and readjust so that you have a barely audible threshold. With the Detech 11" spiral wound coil, which is the coil you appear to be using, the gain should be okay at between 4 to 7. The mode should be okay where you have it set at 3, and with these settings your machine should 'purr'. If this is not the case then you have problems. I would try another coil. [/QUOTE]
