Message-ID: Congratulations to Larry K1UO. Larry was one of our very early adopters of the Hi-Z products. He bought one of the first few 4-square arrays. We are very proud to report that he has been consistently setting records in the 80 meter contests with some help from his Hi-Z 4-square. Here is his latest report. Thanks Larry! HI Lee, Looks like the RX capability of the K7TJR 4 square on 80M allowed me to set a new USA record in CQWW-CW single Band 80M unassisted catagory. I could sure pull out some really weak sigs... Was running so much on one frequency that I neglected to take time to search for mults..but still managed 110 Countries and 32 Zones over the weekend. 73 Larry K1UO So far it looks like it may also be a world record but need more reports. He also reported in a phone call that he was working the QRP stations in EU. WOW! Lee We are now receiving reports from the 8 element arrays that are coming on line. Hi Guys, I did a SOSB 160 using the 8-200 controlled with Green Heron wireless boxes. Conditions were so-so Friday night, not good Saturday night and I missed the European sunrise the second night but I still beat my personal best of 54 countries worked in a 160 contest. The 54 countries were worked during the CQ160 contest, much more participation. During the CQWW I worked 61 countries and 22 zones. I'm ready for the ARRL 160 and plan to do a multi-single. I'll let you know how we do. The K3, HiZ 8-200, Green Heron wireless combination is a winner. I'm trying to get K5KC to buy the 8-200 for his station, do I get a commission? Question, how do the HiZ amps hold up with regard to lightning? Should I be doing anything to protect the amps? Ed/W5TM And, Hello Dick. . . The 8 el narrow 160m array performed really well during the contest this past weekend. In addition to the 8 el array we had wide-spaced Beverages (910' long, 320' spacing) on Europe and Japan. We had the 8 el array on the Aux input feeding the second receiver in the K3. We had the Beverages coming in on the RX input which feeds the main receiver. While we could not exactly do an instantaneous A/B comparison but we spent many hours listening to the two systems in diversity during the contest. The 8 el array definitely hears better than the four square TX array. The 8 el array performance seems to be very close to the phased Bevs with the Bevs having perhaps just a slight edge. . . they're so close in performance it's hard to tell. The two systems hear very differently (which would be expected). Putting them in diversity gave a truly amazing performance. . . a true luxury which very few people have! We did not have Beverages any directions other than EU and JA, so the 8 el array did a great job filling in the gaps. We used your four square array in diversity with the Bevs on 80m. While the Bevs did hear better than the four square array there was still benefit to having both running together in diversity. Overall, our lowband RX capabilities were awesome. We never felt we were RX limited. We are definitely satisfied and very glad we made the investment and are anxious to get the second 8 el array up and going (everything is ready and in place). We did well in the contest but had a brown out (84 volts) and, finally, a total black out for about two hours on Friday night about 0100z. Not being on during those high rate hours definitely hurt us but, overall, we did well. Hope you, Lee, and your families had a nice Thanksgiving. 73 for now. . .Dave W0FLS Thank you Everyone for everything. Keep your eyes out for announcements as we have something coming for a new product that we think will be very special. It wont be long.

I misinterpreted Larry K1UOs record information. He said one thing and I thought it meant something else. hee hee Lee, Correction to your posting..... The 80M score is definately not a World Record...just maybe a world high score this time around :-) 73 Larry K1UO Just a possible USA record...... The North American and World records are much higher !! Me, I think Larry is kickin some airwaves!!!
