The CRES Amateur Radio Club held a general membership meeting on Tuesday, 22 April 2008, at the Southeast Branch of the Columbus Public Library. The following were in attendance: members N9CX, K8AX, K8KJ, KD8BJ, W8AGS, N4DB, K8TX, K8ON, W8REW, WD8EBS, KD8HJA, W3CRZ, WA8LBZ, KD8ZG, K8RSP, K8LJ and guest Bob Perdue. The meeting was called to order by President Bill Erwin at 7:05 pm. Tate/KD8HJA and Greg/KD8FYD were recognized and congratulated on their upgrade to Amateur Extra Class. Congratulations Tate and Greg ! Treasurer's report given by Dave Woolf: Cash Account: $ 179.62 Telhio Chk/Svgs: $1375.87 Telhio CDs: $6314.55 Undeposited Checks: $ 475.00 The undeposited funds are mostly from the liquidation of the items removed from the tower last summer. Rob Stampfli is waiting to hear from Telhio that the new CRES book of checks he ordered is ready to be picked up and will deposit the undeposited checks when the new checks are ready. Bob Cartwright reported that the Field Day site will be Infirmary Mound Park in Licking Co. This will be a spacious location, great for VHF. Final approval for use of the park is in progress. Dave Woolf reported on the repeater. The remote receiver is working fine from Dave's house and the link is running at 50 watts. The repeater amplifier is on Dave's bench and is not working yet. Dave mentioned that we need an amplifier that will take half a watt and produce 100 watts. John Lawson mentioned that the Lancaster folks may have an amplifier they could sell. Dave Woolf reported that the last VE session had 17 people and 9 VE examiners, and 23 exams were given. 14 people passed and 3 failed. The next VE session will be at the Columbus Hamfest which is probably the first Saturday in August. VE examiners will meet at Bob Evans for breakfast at 7:00 am before the 9:00 or 9:30 test session. Old Business: None. New Business: Art Grandle reported that everything has been sold except for the tower and 2 or 3 pieces of hard line. Mrs. Grandle had Art Ask: If the tower is not sold, where do we want it to go? There is a perspective buyer for the tower at $250, but no purchase yet. Bill Erwin said that since Mike Rauh moved to Pennsylvania, we need a new Station Trustee to serve out Mike's term. Dave Woolf volunteered for this. Rob Stampfli sent one ticket for the Athens hamfest and two for the Pennsylvania Breezeshooters hamfest, free for the taking. No one was interest in the Athens ticket, so John Lawson took it to offer it to the Lancaster group. Dave Brown snatched up the Breezeshooters tickets. The meeting was adjourned at ?:?? pm, after which Bob Kenyon gave a very interesting and comprehensive presentation on wave propagation. Bob's focus was on sky wave propagation, refraction via the ionosphere and ground reflection that make world-wide communications possible. The four daytime and one nighttime layers of the ionosphere were described and how they are formed. Details of sunspots and the meaning of sunspot numbers were explained. Other propagation modes such as back and side scatter, rain scatter, tropospheric scatter and ducting were described. W6ELProp, a free public domain propagation software package, was demonstrated. Murphy prevented some on-line input to this presentation from working, but the software demonstration went very well. Respectively submitted, Dave Brown/K8AX CRES-ARC Vice President
