Test it a few hours. Maybe "auto adapt to noise" and "auto amplitude filter" ON give some more efficiency.

Here, try this!   If you haven't, try setting up alternate channel mapping as in http://www.wxforum.net/index.php?topic=22710.0... Now find which H field the noise worse on.    Make sure it's coming from that monster in your backyard.  It's probably near field magnetic, and doing much to E field won't help on the e-field channels... the field might be so strong, that the probe or preamp circuitry intercepts it... in that case E needs to be relocated... it might be as simple as lowering the probe a few feet,  but watching your sigs for awhile, I think, with Alternate Channel Mapping turned on, you can lower gains on E B channel and help that somewhat... that was an impression, and may be wrong on a quick look... you'd still have it on C channel, but you might be able to compromise between A and C, if you follow me.  Now, C channel is the most important one... so even if you have to 'sacrifice' those so-called effectrivity/efficiency figures to contribute with "quality'. if It's e field, there's not a lot you can do, except relocate e field antenna somewhere at minimum disturbance.  If it's H field, you could run that channel, and also E field (A or B at different thresholds/gains, if you're in Alternate Channel Mapping.  I've found the best way, overall, to locate and eliminate noise sources is to stay full manual, no filters, and play with the things as you track it down, or do the things necessary to mitigate the noise.  If your're not running "Alternate channel mapping' the way we explored it, than your settings can 'interfere' for lack of a better word, with the 2 different amps.    It is also possible that that monster down the hill has a 'better' or 'worse' ground than you have on the controller. It only takes a tiny amount of difference to mess stuff up, and go 'ground looping'.  I had to play with 'controller' ground a bit before I found that the Television Cable ground connection was best in my location.  One other thing you could do, if it's the monster, tell the Utilities company that you cannot receive AM radio, and it's due to radiation from that thing... .  Rolleyes

seriously... when I first set up, I had an awful time with H field... it took some time to find the best spot for locating H field ferrites.  But this made it easier to locate the E field assy, later on.  Now, my environment has changed, somewhat, and I'm having difficulty resolving the issues.  However, because I had determined my 'baseline' environment, I can accept the junk, and adjust, as needed.  Auto Mode does NOT work well for me, it may later, with the release of BLUE, and the developers bring it our of what is still "BETA".... the 'so called' 'auto amplitude' and 'adjust to noise level' are also unsatisfactory, in my environment... I'm best in 'manual', and learning how to 'judge' the current environment... I 'don't ride gain', but I do some evaluation before modifying any settings... .

Also, remember, it's possible not all of your 'junk' is from 'the monster'... a couple of Operators and I have attempted 'matching signals'... and in all instances, we'd both log the same signal, not accepted by the server, though we were several hundred miles apart.  Some of it looked exactly like 'a nearby sodium vapor light', which was impossible.  Try the above, if you haven't, don't beat your head on the wall, this is part of the 'fun'   Big Grin  

I just reread this.. sounds pretty rambling... sorry. Hope you can make sense of it...
