How long is your BOG on the ice? Here's a study I did several years ago, measuring daytime signals from both ends of an unterminated BOG. http://www.dxing.info/community/viewtopic.php?f=17&t=371 As you can see there's some built in F/B with unterm. BOGs. I believe this is due to the fact that BOGs are quite lossy and the back end signals travel further along the wire as they reflect back to the rx. The same effect was observed in WI when I tested a 470 footer. The same effect happens with shorter BOGs, but is less since there's less loss.Re: your logging on Lake County IL TIS on 1620. Currently I think there are 5 of these on the air. All seem in syncro and use WQBR256 calls. I am not happy to have the Lake Zurich one on now, at most 2 miles from here and ruining 1620. The one that really gets out is the one in Lindenhurst near the WI border. I can get that daytimes 60 miles north at my WI house. As for logging these at your distance and having no way to know which one(s) your hearing, just call it WQBR256 syncros and as 1 station. There are certainly other TISs using the same calls for more than 1 xmtr.73 KAZ -----Original Message-----From: Saul DX <sauldx@xxxxxxxxxxxx> Sent: Feb 12, 2011 10:05 AMTo: Mailing list for the International Radio Club of America <irca@xxxxxxxxxxxxxxxx>, amdx@xxxxxxxxxx, amfmtvdx@xxxxxxxxxxxxxxx, am@xxxxxxxxxxxSubject: [NRC-AM] More greyline DX, and antenna question More fun tbis morning pos-sunrise. lapeer MI 1230, then 810 Tomahawk WI, both new. The latter has been on my most-wanted list, been chasing that awhile. Both WI stations on 910 are relogs. When MI was huge I was looking for WGTO Cassoplis MI which is on my hit-list. Nabbed the 1620 HAR from north of Chicago again, albeit very briefly. I am wondering if the good cx to the west this trip reflect the temporary BOG I laid out on the ice facing west. It seems every time I do this, I dowell to the west. Last year it was a beaut session to BC/AB. This year everytime I have laid a wire on the ice I've done well in that relative direction. Ironically, I have done less than stellar in the opposite direction (east) - and given that the antenna is unterminated I am a bit puzzled (though happy to evade the east, which is generally what my unterminated wires through the woods have yielded for me, so the change is welcome). Is it possible my radio (at the east end of the wire) acts as a partial terminator?
