Hi KAZ, Thanks for your comments about Tim's 612-4QR reception in Michigan. I've always had a special interest in extremely long range DU receptions like this in Michigan and Illinois, and also in Richard Allen's long range Asian TP receptions in Oklahoma. <<< Gary, occasionally we can get threshold or a bit better (Tahiti) audio from a few DU's here in the upper Midwest. It takes a rather quiet location and a good antenna system along with a first class rx. >>> Well, any time a DXer in the Midwest can get audio from Tahiti, Australia or New Zealand, it's an outstanding achievement. But it's kind of a puzzle to me why these DU's occasionally show up in the Midwest on the Perseus-SDR's and DKAZ antennas, while the Asian TP's that Richard receives in Oklahoma on his simple Ultralight radios and 8" FSL antenna are not showing up in the Midwest (and vice versa). At these extreme distances, I guess it all depends on which frequencies are clear of local pests, and which ones are plastered by domestic splatter. In his search for 738-Tahiti, I know that Richard has a tough time with 740-KRMG in Tulsa. <<< I don't think the rather high solar activity this year would effect paths to DU from here. OK if it were AU enough to clobber KOA and prevent anything from CA from sneaking in, OK it would likely kill DU's. But things aren't that AU and these semi AU effects, which ruined late Oct sunset skip to the west tend to dissipate a couple of hours after full sunset along the path. >>> Here on the west coast the high solar activity has certainly reduced our expectations in Asian TP-DXing, and I doubt that any of the active TP-DXers expect to track down much exotic Asian DX either at our home locations or during ocean coast DXpeditions this fall season. There are a few fanatics like Nick, Nigel and I that continue to check the band almost every morning, but it's important to have reasonably low expectations during this lean solar year. There are enough twists and turns in the daily Asian propagation to keep things fairly interesting, but none of us really expect Asian results like we had in 2009 or 2010. Such unrealistic expectations would only lead to disappointment. On the other hand, summertime DU-DXing propagation to the west coast is not only unaffected by the solar activity, but seems to be enhanced by it. Chuck, Bill and I all had outstanding New Zealand results this past summer during our ocean coast DXpeditions, with Chuck alone probably receiving at least 10 all-time new Kiwi stations for the west coast during our Rockwork 4 DXpedition. During these lean solar years summertime DU-DXing will certainly be a major attraction for serious west coast DXpeditioners, and provide the lion's share of exciting new DX catches. <<< I almost had 612 here one morning nearly a decade ago when IBOC was in its daytime only testing phase. 612 had a good carrier that was increasing in strength and we were just a couple minutes before the sunrise peak with a few other carriers also decent. Then WMT IBOC came on and ruined it. Thankfully WMT IBOC is long gone. WTMJ IBOC should have no effect on 612 unless you were very close to WTMJ. >>> Good luck in tracking down 612-4QR in Illinois, KAZ. I'm happy that the WMT IBOC is no longer a problem. Curiously enough, the DU's which seem to be the best bets for the Midwest are not usually the best performers during the west coast DXpeditions, at least for me. 576-2RN, 774-3LO, 792-4RN, 891-5AN and 1116-4BC are the Australians which routinely reach S9 levels during good conditions on the ocean cliffs, while 612-4QR and 702-2BL usually lag behind in strength. The best Kiwi performers are 531-PI (with awesome strength last summer), 567-RNZ, 603-Radio Waatea, 657-Southern Star, 675-RNZ and 1503-Radio Sport. In general the Kiwi DU's do seem to run out of steam the farther you get from the salt water, although Nigel in Alberta certainly has tracked down some incredible New Zealand catches, such as the 1 kW 1584-Coast Radio recently. 73, Gary DeBock (in Puyallup, WA) ----- Original Message -----
