Why thanks, Bill. Re: DU's, if I send you an audio clip of 738 2NR from Monday, you'll be shocked at the level as it is about the clearest DU ever heard here in IL. My lack of noise, may make you want to move. Noise is down considerably here compared to last year. It was more quiet in the mid 1990's here, but this is pretty good and very helpful to have little noise most of the time.
Sunrise has been stunning with many new additions from the west coast. As an example, Monday at 7 am local CDT, mixed under an unID SS rlg stn, are two "The Answer" slogans run together from male voices that are slightly different. So that is KTRB (needed) and KPAM (not needed as logged via SSS a few times). With even a slight noise level, I'd likely not have been able to copy that. A few minutes later XEMO (common lately) IDed so that is 3 west coast stations on 860 within a couple minutes at sunrise. With the reduced noise level, I am thinking about re-installing a 2nd West DKAZ for a broadside phased array. They will be too close to help out much at the bottom of the band, but this array proved very useful higher up two seasons ago. ie...KSTP 1500 basically gone and with a twist of the switch to switch phase, KRJO 1680 gone making KNTS basically a pest as the terminations clobbers WPRR. 73 KAZ Barrington IL On Wed, Oct 24, 2018 at 6:54 AM His <b...@his.com> wrote: > Fascinating discussion.
