WD9EWK from Tucson AZ hamfest and DM51/DM52/DM53 - report
by Patrick STODDARD (WD9EWK/VA7EWK) 08 Apr '09

08 Apr '09

Hi! Saturday (4 April) was a great day, between the hamfest in Tucson and taking a quick 300-mile/500km road trip after the hamfest to go back home. I was able to do demonstrations at the hamfest in one grid (DM42me), and then operate from 3 other grids in the afternoon (DM51, DM52, DM53). ***** Tucson AZ, Radio Society of Tucson "Desert-Fest '09" hamfest (grid DM42me): http://maps.google.com/maps?f=q&hl=en&geocode=&q=32+10.792+N+110+55.819+W&i… I drove to Tucson the Friday evening before the hamfest, so I would not have to make the long drive in the dark early on Saturday morning. I was out there before 0530 local (1230 UTC), setting up my AMSAT table and getting ready for the first of 4 passes I worked at the hamfest. At 1349 and 1529 UTC, I did demonstrations on AO-51. The first pass, to the east, yielded 11 contacts from all over North America. The later pass had 5 more contacts, and a lot of intermod from some transmitters in downtown Tucson to the west of the hamfest site. Later in the morning, I had VO-52 passes at 1556 and 1730 UTC. Fewer contacts were made on those passes compared to the AO-51 passes; only 1 QSO on the first pass, and 2 on the later pass. Thanks to all the stations across North America that made contacts with WD9EWK, and my apologies if I did not work your station. I have to thank Randy Malick KF0X and the Radio Society of Tucson for allowing me to bring an AMSAT table to their hamfest, the first for this club. Randy had traveled to other hamfests and events across Arizona over the past few months drumming up interest in this event, and his efforts paid off. The RST club even provided WiFi Internet access to those at the hamfest, thanks to the RST's D-Star repeater network. After the hamfest, it was time to hit the road... ***** near Sunsites, Arizona, in Cochise County (grids DM51bx and DM52ba): http://maps.google.com/maps?f=q&hl=en&geocode=&q=32+0.00+n+109+54.925+w&ie=… I had planned on operating from grid DM52 in southeastern Arizona during the day, before heading toward grid DM53 for the AO-51 passes in the evening. I glanced at my maps, and saw I could make a stop at this spot - a spot I visited in May 2008 - and put DM52 on the air as well as grid DM51. I figured I could stay for the AO-27 pass at 2030 UTC and the SO-50 pass at 2100 UTC, and still be able to drive up to DM53. That was what I did. After finding the spot on a side road running parallel to US-191, I took pictures and set up my station for the pass. When the AO-27 repeater switched on, I started making contacts. In 7 minutes, I made 10 QSOs. A little later, I logged 10 more contacts on SO-50. All of these contacts were with stations all over the USA, and - at the end of the SO-50 pass - Adrian ZF2AE in the Cayman Islands popped up for a quick QSO. This was a nice stop, logging 20 contacts between those two passes. I will try to return to this area next month, with a hamfest in Sierra Vista southwest of here - if there's still interest in these grids. ***** south of Safford, Arizona, in Graham County (grid DM52do): http://maps.google.com/maps?f=q&source=s_q&hl=en&geocode=&q=32+36.227+N+109… After my DM51/DM52 stop, I wanted to work north toward DM53 in time to look around with lots of sunlight. I went north on US-191, and saw that the western AO-27 pass was coming up around 2210 UTC. I pulled off the highway, onto range land that was alongside the road, to set up for the pass. When the AO-27 repeater switched on, I made 3 quick contacts with Mexican stations. After those contacts, I was visited by a Bureau of Land Management ranger. The ranger drove up and took an interest in my handheld log periodic. He wondered if I was tracking animals with transmitters. I said that I wasn't doing that, but I could with the radio equipment I had. I told him about talking with other ham stations via satellite, and asked if there was any problem being at this location. The ranger said "no", told me I could continue, and he drove off. All of this took place in the span of about 3 minutes, approximately half of the 7-minute AO-27 pass. In the last couple of minutes, I worked KL4E and KL7XJ in Alaska. This was probably the first time I had an FM satellite pass where I worked stations in Mexico and Alaska, but none in the continental USA. After the pass, I got back onto the US-191 highway, and went to the town of Safford... ***** Safford, Arizona, in Graham County (grid DM52dt): http://maps.google.com/maps?f=q&source=s_q&hl=en&geocode=&q=32+48.161+N+109… This was a quick stop on my way to grid DM53, and an SO-50 pass at 2243 UTC. Safford is in the Gila River Valley and next to Mount Graham, 10720 feet/3267m high. Mount Graham is home to several observatories, which I did not visit on this trip. I might come back and visit them in the future. I parked in the parking lot of a high school, and was ready for the satellite. For some reason, there was a lot of interference during this pass. I was able to log two QSOs, with KL7XJ in Alaska followed by AC6P in California. After this pass, I had approximately 2 hours to find a spot to work from during the upcoming AO-51 passes. ***** south of Fort Thomas, Arizona, along US-70 in Graham County (grids DM52ax and DM53aa): http://maps.google.com/maps?f=q&source=s_q&hl=en&geocode=&q=33+0.00+N+109+5… Northwest of Safford, US-70 runs parallel to the Gila River toward Globe. About 18 miles/30km northwest of Safford is 33 degrees North latitude, the line between DM52 and DM53. US-70 cuts through the southwest corner of DM53, and I didn't have many options for setting up in this area. I used the tactic I employed last fall for working from the DM23/DM24 line in California, parking at the spot only for the passes. This worked. The first pass to the east was at 0056 UTC. Still lots of sunlight, and the moon was visible in the eastern sky. This turned out to be the busiest pass I have ever worked on an FM satellite. Stations from all over North America showed up, and I logged 28 QSOs. Six of those were with Mexican stations, two with Canadians, and the rest were spread out all across the continental USA. As the sunlight went away, I had one more chance to work AO-51 from this spot. I started putting my callsign on AO-51 around 0237 UTC, and shortly after that XE2RV came on. After chatting with Rafael for a couple of minutes, waiting for more stations to join in (we were leaving gaps for others between our transmissions, and inviting them to join the fun), I made contacts with 6 other stations in the US and Canada. Now that I know an easier way to get from Phoenix to DM53, I can return to this location in the future. ***** I am happy to send out QSL cards for anyone who made a contact with me during this day-trip to Tucson and southeastern Arizona. Just e-mail me the QSO details, and - if you're in the log - you will get a card. I am finishing up the design of these cards, and will get them in the mail - along with cards from my other recent trips - over the next few days. I have lived in Arizona for over 3 decades, and had never been to the part of Arizona in the northern part of DM52 around Safford and DM53. It was a nice drive, and it was fun to work the satellites during this trip. After Saturday, there are only 3 grids left for me to operate from in Arizona - DM31, DM54, and DM55. Time to work on those... :-) 73! Patrick WD9EWK/VA7EWK http://www.wd9ewk.net/

Amsat Folks, Any recommendations as per sstv software? I was looking for something open source, so that I could perhaps hack at the code in my free time. My only find was Digital Master 780. http://www.ham-radio-deluxe.com/Downloads/GPLOpenSourceCode/tabid/61/Defaul… Are there any others around? I wanted to put this out there to see what other more experience hams have used. Thanks in advance! Joseph Armbruster KJ4JIO

I'm sorta a newbie at this, altho I did work the early Oscars and RS birds. I have decieded I wanted to work the sats again only I forgot most of what I knew. hi Last nite I listened to the 2M downlink for VO-52 and I'm hooked. I tried sending dits on its uplink but was very weak, when I switched to SSB I could not hear myself. Here is what I was using for the downlink my FT-857D into my 9 el M2 yagi at 25ft, for the uplink a FT-817 into a homebrew 5 el 435 yagi on a tripod right next to the desk. Tonite I'm going to reverse it and use my FT-857D for the uplink. I prefer CW but so far have not heard any. I'm not even sure what part of the band CW is used. Could someone give me a example I want to be on the middle of the CW band. Where do I set the Tx, and then the Rx. If I had some examples I could figure it out but right now I'm clueless. Got to rearrange my station to get it ready for later tonite. I will probably be a pest constantly asking questions till it all comes back to me.

by Vincenzo Mone 07 Apr '09

07 Apr '09

Hi Folks, sorry for the OT message. I own the rotator Yaesu G-5400B which are a Azimuth and elevation rotators. I had enclosed with the pack when I bought it an "L" bracket. Unfortunately due to maintenance I have lost the Bracket. Please is there anybody which own one and can pass me all the measures So I can build a new one? I need the measures of the "L" bracket and the right Positions of the holes to fix the two rotators. Any help will be really appreciated. Thanks in advance I want to thanks to Jim K6CCC and Stan W1Le for their replies but the problem is that They have the "U" bracket while i need the measurements for the "L" Bracket. The rotator was bought in the far 1990 and it was received with the "L" bracket and The Elevation rotator has just 4 holes on one side while the new one has 2 holes on On the bottom of the two sides. 73 de Enzo IK8OZV EasyLog 5 BetaTester EasyLog PDA BetaTester WinBollet BetaTester D.C.I.
