One thing that always amazed me was how far out you have always been able to hear WAMM/WFLT 1420 Flint. I don't remember hearing it in West Central Michigan, maybe it was due to pre NRSC sidebands from WBRN 1460, and I never tried very hard when WBRN was off. But I heard is alone near Houghton Lake once when it was strictly a daytimer and close to middays in the Summer. I heard WFLT recently near Pinconning, and people posted elsewhere about getting it regularly near Tawas. WKMF/WFNT 1470 Flint is another signal that amazes me for as far up the dial it is. Like I said, it was quite clear when WBRN was off the air at that location and set up. I have heard it in the Summer in the daytime near Charlevoix, and in the Straits Region quite regularly in the daytime with a similar set up as in West Central Michigan. I knew the CE at WKMF/WFNT back when I had more time to DX, the late Bill Sanderson, and he was amazed also. WCRZ 107.9 Flint used to also come in at the same location with an FM-10 and Technics ST-G5, which has the digital readout signal strength meter. It was at 14 dB on the meter quite consistently in the Summer, before WCZW Charlevoix came on the air. You could hear WGMZ/WCRZ ALL OVER THE LOWER PENINSULA on a fairly regular basis before all the newbies on 107.9 came on the air. The same was true of most of the Class B stations in Michigan at near full Class B ERP and the grandfathered superpowered stations.
I attribute the great signals of WAMM/WFLT 1420 and WKMF/WFNT 1470 to their location in a swampy clay soil era next to tributaries of the Flint River. WTRX 1330 Flint, received interference from WHBL 1330 Sheboygan in Northern Michigan. If you listen near places like Mio and Atlanta, you can hear them alone but fairly weak with WTRX. I haven't tried WFDF on the far Eastern Sunrise Side much, but all of those still come in quite well in Tawas and Harrisville I am told with the new TL and 50000 watts. WFDF got and gets interference from WDOR 910 Sturgeon Bay, and WTAC/WSNL 600 from WLST...WCHT 600 Escanaba the futher West you go.
Of course, rfry, David, and HGR1290, radioman, cyberdad, etc. have all noted WSGW 790 Saginaw all over the place before WBBM went IBOC and far enough from CKLW 800 to not have adjacent channel sideband interference.
WWJ was weak in those areas but came in quite well with the longer wire vertical and preamp with 5000 watts nondirectional, and had a decent signal in Northern Michigan at night with 5000 watts DA. And as I noted before PSSAs and Fulltime newbies came on, WWJ could regularly be heard hundreds of miles in most directions at night with 5000 watts. The higher tower disappeared at a certain angle, and it was essentially Non-DA at the corresponding distances.
