Go and find a page on WA5VJB "Cheap Yagi" designs, and build a 2m and 70cm one sharing a boom, 90 degrees apart. Build a wee diplexer (HB9ABX's design is good) if you want to feed both aerials to the same radio, or just work split. Dead easy.

[amsat-bb] Tucson hamfest and DM51/DM52 on Saturday (27 March) - report
Hi! Saturday was another fun day, between the Radio Society of Tucson's spring hamfest and my drive to the DM51/DM52 boundary in southeastern Arizona after that. The hamfest had a good turnout, despite its location being changed at the last minute. The trip to the grid boundary was also enjoyable, since I had not been out there in almost a year. I had been in the general area after another hamfest in Tucson last October, but on that day I drove to the Arizona/New Mexico state line in DM52 for some passes that afternoon instead of heading to a grid boundary. This was the second time the Radio Society of Tucson hosted a hamfest in the springtime. Last year's event was a huge success, after many years of a mid-October hamfest in Tucson. These events have been held at the same location southeast of downtown Tucson, but there was a change last Wednesday to the location. Thankfully, it only moved across the street next to a baseball stadium. People were showing up as early as 0530 local (1230 UTC), even without any lighting turned on for the lot where the hamfest was at. As everyone started setting up, using flashlights or vehicle headlights until sunrise, small groups would wander to see the merchandise before the official start time (0700 local/1400 UTC). I had an AMSAT table set up then, and was on an AO-51 pass just after 1330 UTC. This would be the only FM satellite pass for the morning, and I had a nice crowd listening to this western pass despite it being a half-hour before the official start of the hamfest. As the sun came up from behind the mountains to the east of Tucson, I was able to do a couple of other demonstrations for the hamfest crowd. AO-7 went by just after 1400 UTC, and I was able to work a few stations. Lots of hams were curious to know how and when AO-7 came back to life, and I was happy to explain that. There was a low VO-52 pass just after 1530 UTC, where I worked one station on that pass (Roger W5QEP, in Louisiana). Thanks to Jeff K7WIN, who used my phone's camera, I have a YouTube video from this VO-52 pass. You can see it at: http://www.youtube.com/watch?v=LA2VEb8xr-c Davis-Monthan Air Force Base, a few miles/km east of the hamfest site, made working FO-29 impossible at the hamfest. There is a data- communications system on the F-16 aircraft at this base, and that system wipes out the FO-29 downlink. FM satellite downlinks don't seem to be affected by this system. It also plays havoc with 70cm repeaters in the Tucson area. Otherwise, I would have liked to try that satellite for some of my demonstrations. At most hamfests, I'll get lots of questions on how someone would start out on the amateur satellites. This time, I had more detailed questions on that topic. I was asked about specific radios and antennas, and whether those would be suitable for satellite work. I've been making the trip down to Tucson for the past year and a half for their hamfests, and others have done this before me, so it is nice to see that some are thinking beyond the "what do I need?" types of questions to see if they already have the gear to try this out. Throughout the morning, I saw a few satellite operators like Leo W7JPI, Ron W6ZQ, Rafael XE2RV, Ed N7EDK, and Jeff K7WIN who all live within an hour's drive of Tucson. It's fun to chat with fellow satellite operators, just as I enjoy answering questions from those who are interested in trying this part of the hobby. Thanks to the Radio Society of Tucson for allowing AMSAT a space at their hamfest, and to those who made contacts with WD9EWK during the 3 on-air demonstrations. ** After a quick stop for lunch before leaving Tucson, I drove a little more than an hour to the spot I have stopped at in the past along the DM51bx/DM52ba grid boundary. This location, 32 0.000 N 109 54.927 W (you can put that into the Google Maps web site, Google Earth, and possibly other web sites and programs), is along a road west of US-191 and south of the I-10 freeway in Cochise County. I like this spot, since I am off the main highways yet have a decent view of the sky from here. Only shallow passes to the west are problematic at that location. I had enough time to set up and be ready for the first pair of passes to the east. AO-27 was passing by at 2111 UTC, and SO-50 would be in view as AO-27 shut off. Lots of activity on both passes, and I was surprised to hear Drew KO4MA call me at the end of the SO-50 pass at 2126 UTC. Since Drew has been working the satellites much longer than I have, it was a pleasant surprise to hear Drew tell me he needed both of those grids. After those passes, I had almost an hour and a half until I had three passes (AO-27, then SO-50, then AO-51) stacked up. I went to a nearby convenience store to get some drinks. When I pulled up, there was a cat sitting on top of a drink cooler just inside the front door of the store. With camera in hand, I snapped a couple

[amsat-bb] Schedule for today for AA5UK/KH6 BL02ic
Folks, We had some torrential rains and very heavy wind this morning. There was no way for me to operate the 3/29/2010 15:57 UTC AO7 pass. We are expecting more heavy wind all day but the rains have at least stopped. Essentially there has been heavy rain every morning but today was the worst. Think of going through a car wash. Here is my operational schedule for today 3/30/2010 All times UTC CONUS contacts: FO-29 @ 03:38 UTC FO-29 @ 05:20 UTC VO-52 @ 06:15 UTC JA contacts: I will have a partial pass to JA during FO-29 pass at 07:07 UTC. I will be looking for JA 's on SSB only. I can only make about half the pass as I have a house in the way but I will try. There are some mountains in the distance but the satellite may be able to clear them. I guess we will just have to try and see. All for now. Going to get some rest since I am on vacation. I am starting to look at the HO-68 schedule to see what opportunities open up in the coming days. Aloha, Adrian AA5UK/KH6 ___ Sent via amsat...@amsat.org. Opinions expressed are those of the author.
