[IRCA] Day ONE at Grayland
Kevin Schanilec and I were able to get both Wellbrook arrays up on Friday afternoon: a phased array of 2 triangular K9AYs and another massive new array of two 17' x 60' Super Loops. Both arrays were pointed NW and were separated and staggered by about 150 feet. It was quite a job including a total of 6 self-supporting masts and two large sets of radials (for the K9AYs.) After one night of testing, the Super Array appears to be superior to the K9AY in forward gain, and possibly having a slightly narrower front lobe and each rejects the backside about equally (which means that the Super Loops are actually rejecting things much better given their larger size and increased forward gain.) There is a lot more testing to go, and a possible decrease in the size of the Super Loops, but things are looking REALLY promising. We were talking over when to get up this morning and remembered that this late in the season, things are often better an hour or two before sunrise, with dawn enhancement being very mild. So, we started out 1220UTC (LSR=1440) and were welcomed by almost wall to wall DX with many signals the strongest that I have heard them this season! It was exactly like September, all over again: the Japanese, large and small were very much favored, with little or no co-channel interference from mainland stations. 531 JOQG Morioka, NHK1, usually at murmur or, at most, fair level was stronger than I've ever heard it. I enjoyed a bit of the Japanese World Series between Tokyo and somebody. "Home-uh Run-uh" Just like in September, the Big Gun Chinese and Korean stations were in, too, but the second and third tier were missing. By 1315, still 90 minutes before dawn, the band had dropped in average signal about to wqhere we have been experiencing it lately and the smaller mainlanders began to appear. There was a bit of a boost at dawn, but it was certainly weak compared to "normal," and the coastal effect kept the DX coming in until 1540, a full hour after dawn. When we shut down, all of the Big Guns were still putting in audio, but the real DX was gone. The more interesting loggings: 549: Mayak/ Rossii with an excellent signal and a definite echo //279 which was booming in, itself. The 549 signal was likely Vladivostok+Magadan. 576, usually the far stronger Russian, was totally missing (and we thought off the air) until near dawn when it was noted in parallel. 738//1143 Taiwan Fisheries was excellent much of the time and 1143 was really strong at dawn. 810 R.Rossii totally dominated KGO at times throughout the morning. 837 In the early going, this was JOQK, Niigata, NHK1, by itself. Later, presumed Harbin was on top. 999 early was a Chinese, not CNR1 or 2. Most likely Liaoning. Later, it was the Korean Christian station, HLCL 1026, Beijing Economic Radio was in very well and was IDing "FM xx.x, AM 1026!" They did that four times in as many minutes. Is this the beginning of the end of AM radio in China??? IDing FM first, WOW! Big change for the Chinese to even have FM simulcast, much less ID it first! 1116 JODR, Niigata was the big catch for me this morning. Its a relatively small commercial station on the Japan Sea side of Honshu. New station for me. 1134 had the JJ and KK on it, but it also had the rare CNR1 in Qinghai Province, over near Tibet. The imponderable of the morning was on 900 at 1500. With these antennas, Victoria was largely missing until WELL after dawn. At 1500, it was beginning to come up. There was another station under it, also playing quiet music. At 1500, the CNR time pips were heard and what seemed to be the fanfare/anthem and other parts of the CRN2 TOH routing. If so, this is the OTHER station in Golmud, Qinghai If I had Perseus, I could re-run that at check parallels. Oh well! So, that is it for day one Meeting Kevin S. face to face for the first time has been fun. Little did we know, but we both go to the same barber (our heads resemble bowling balls :>) More tomorrow!

Re: [IRCA] Day ONE at Grayland
This is good news about the arrays. Once again I will stress that I think end fire arrays of two cardioid antennas will be a major step forward for those with the room to use them (home users need a good sized yard) and whom are only interested in one general direction. I presume that you were using Wellbrook components for both arrays? My appologies to all for not yet testing the 2 KAZ (delta flag) array here. My bad back has returned and is becoming chronic once again. I can cope with the pain to lay out wires on the ground and phasing them, but getting up a ladder to trees for cardioid antennas is currently out of the question. Anyhow..I am so happy to see you guys testing two loops !!! I presume that both these arrays are basically set and forget and give great back end nulls across the entire band? If so then there's all sort of interesting possibilities for pattern improvements..ie more narrow main beam or phasing something out off to the side of the main beam if you phase one array vs the other (although I think you'd space them further than 150 feet apart) Hmmm Russia clobbering KGO 810.. that sounds like awesome F/B to me! Your Chinese logging on 900 past Victoria indicates a rather narrow beamwidth as well ! Looking to read more.. 73 KAZ - Original Message - From: "John H.
