WD9EWK's 17-22 July 2008 road trip report (long)
by Patrick STODDARD (WD9EWK/VA7EWK) 30 Jul '08

30 Jul '08

Hi! This was a fun trip. Including a couple of days at the hamfest in Williams, Arizona, I spent 6 days on the road and traveled a total of 1603.5 miles/2580km. I operated from 10 different grids in and around Arizona, and logged 169 contacts. At the hamfest and throughout this trip, I used the same station from the back of my Hyundai Santa Fe - an Icom IC-2720H 2m/70cm FM mobile radio at either 5W or 15W output, into an Arrow Antennas handheld 2m/70cm Yagi. I used either KD2BD's PREDICT program or the AMSAT web site to know when the passes would occur, coupled with the AO-27 Satellite Scheduler program to know when the AO-27 repeater would be on during those passes. Thursday (17 July) afternoon and evening, from grids DM35xg and DM45ag east of Williams AZ: http://maps.google.com/maps?f=q&hl=en&geocode=&q=35+15.570+n+112+0.00+w&jsv… Since I was heading to the hamfest in Williams a day early, and would be doing demonstrations from there (grid DM35vg), I decided to spend some time east of Williams on the DM35/DM45 boundary. I operated from the same spot I used in mid-April, along old route 66 north of the I-40 freeway about 10 miles/16km east of Williams. Lots of trees and shade, and a great place to play radio. I arrived in the area in time for a very high SO-50 pass at 1940 UTC, and worked just 2 stations. After driving to a nearby truck stop to get lunch, I returned for two AO-27 passes at 2051 and 2232 UTC. I made 11 contacts between those two passes. I then drove to Williams, to see where my AMSAT table would be at the hamfest, check into a motel, and then returned to this spot for an evening AO-51 pass (0220 UTC, 18 July). I only made 8 contacts on the evening pass, not bad for the first of several days on the road. Friday (18 July) and Saturday (19 July), from grid DM35vg at the Williams AZ hamfest: http://maps.google.com/maps?f=q&hl=en&geocode=&q=35+15.511+n+112+11.105+w&i… AMSAT had a table in the vendor hall at the hamfest, which saw a lot of traffic. Along with that, I did demonstrations from outside the hall. I had good crowds for each of the 4 demonstrations I did. I did demonstrations on AO-51 and AO-27 on Friday, and AO-51 and SO-50 on Saturday. I had hoped to do an AO-27 demonstration on Saturday afternoon, but a thunderstorm cancelled that plan. For the 4 passes, I made a total of 22 contacts. Not bad for those demonstrations. I answered lots of questions from hams passing by the table, so I considered this a successful hamfest. A regular on the FM satellites, "Uncle" Larry WA6DIR, stopped by while traveling east - nice to see him around the hamfest. Sunday (20 July) morning, from grid DM46vr in Kayenta AZ: http://maps.google.com/maps?f=q&hl=en&geocode=&q=36+42.520+n+110+14.895+w&i… Since the hamfest was only scheduled for Friday and Saturday, I had thought about taking a road trip for a few days after the hamfest. Some sightseeing, and - of course - some operating from wherever I happened to go. I drove over 500 miles/800km this day, and was able to operate from 4 different grids in northern Arizona and southern Utah. I left Williams early, and about 2.5 hours and over 160 miles/257km later I stopped for lunch at Kayenta - a small town on the Navajo Nation reservation in northeastern Arizona. At this point, I was less than 50 miles/80km from the location I hoped to operate from in the afternoon (the DM56ex/DM57ea boundary near the Arizona/Utah state line), and about 40 minutes from an SO-50 pass. A gasoline station at the junction of US routes 160 and 163, the southern approach to Monument Valley, was a good place to work my first pass of this day. After 8 contacts in 10 minutes during the pass, I packed my gear and moved east to the next location I would operate from - as I finished my lunch on the road. Sunday (20 July) afternoon, from grids DM56ex and DM57ea in southern Utah: http://maps.google.com/maps?f=q&hl=en&geocode=&q=37+0.00+n+109+36.567+w&ie=… After less than an hour, I reached the next spot I would operate from - the line between grids DM56ex and DM57ea in southern Utah along US route 191, just north of the Arizona/Utah border. The Arizona/Utah state line at this point is just south of the grid boundary, in San Juan County and still on the Navajo Nation. This would be the only stop on my trip where I would operate from Utah. This is a very remote spot, a location that several regular satellite operators told me they needed for their logbooks. Once I confirmed the location with my GPS receiver and took some pictures, I set up for the SO-50 pass at 1925 UTC. This pass only covered the west coast of North America, and I made just 4 contacts. After this pass, I drove around this area to look around before the upcoming AO-27 passes. When AO-27 turned on at 2106 UTC for the first pass of the afternoon at this location, to the east of my location, it was busy as usual. Once stations heard my location, I started working them quickly. Seventeen stations logged in 7 minutes! This might have been a personal record, and I thank all of the stations on that pass for cooperating with my attempt to hand out contacts from this location as quickly as possible. I had hoped to work the next (western) AO-27 pass from here, before driving to my next stop for the night. A thunderstorm with lots of rain and lightning near me changed that plan. I packed my gear, and moved on. Sunday (20 July) evening and Monday (21 July) morning, from grids DM46fx and DM47fa near Page AZ: http://maps.google.com/maps?f=q&hl=en&geocode=&q=37+0.00+n+111+34.270+w&ie=… Over 150 miles/250km of driving from DM56ex/DM57ea brought me to Lake Powell, on the Arizona/Utah border. Once again, the Arizona/Utah state line was not the grid boundary. This time, the grid boundary was on the Arizona side of the state line. I found the spot I wanted to work from, near US route 89 south of the state line and Lake Powell, and waited for the AO-51 pass this evening (0200 UTC Monday). This pass was virtually overhead, so I planned to work only this pass this evening. These two grids are another pair of rare grids on the satellites, and the overhead pass meant lots of stations to hear and work. I worked a total of 19 stations from central Mexico to Alaska and Canada's Northwest Territories (the first time I've ever worked a VE8 station, on any band or mode!). After the pass, it was time to find a motel for the night and rest up before another day's drive. I had driven over 500 miles/800km today. I was able to work another AO-51 pass on Monday morning just before 1600 UTC, logging 4 more contacts. With 23 contacts from these two grids during 2 passes, I thought that was a good effort. Monday (21 July), midday, from grid DM36pu west of Fredonia AZ: http://maps.google.com/maps?f=q&hl=en&geocode=&q=36+52.318+n+112+40.515+w&i… On my way west toward Las Vegas, I stopped along Arizona route 389 west of the small town of Fredonia for an SO-50 pass. I wanted to put grid DM36 on the air as much as possible, before reaching Las Vegas later in the day, and this was a convenient stopping point. I did not want to go further west, as I would get closer to a wall of mountains to the north. Since there was a gasoline station near this spot, I went there to get some snacks and something to drink before the pass. This area is called the "Arizona Strip", between the North Rim of the Grand Canyon and the Utah state line, where very few people live. When SO-50 was audible around 1814 UTC, I was surprised to hear several stations on a pass during the middle of a weekday. I logged 7 contacts from this spot, before moving to another location on the west edge of DM36. Monday (21 July) afternoon, from grid DM36at near Scenic AZ and Mesquite NV: http://maps.google.com/maps?f=q&hl=en&geocode=&q=36+49.994+n+113+59.929+w&i… I was driving hard to get to this area before the two AO-27 passes this afternoon, and saw a tall line of mountains to the east. I did not have time to get to the DM26/DM36 grid boundary in this area for the first AO-27 pass, a shallow eastern pass. I was hoping to get on from DM36 for these passes, as I knew I could be on from DM26 later in the day at Las Vegas. When I parked at this spot, next to the I-15 freeway a few miles/km east of the Arizona/Nevada state line in Mohave County, I was ready at the scheduled start of the AO-27 pass. Due to those mountains, I lost the first 30 seconds or so of the pass, before the satellite was clear of those mountains. Even with that, I was able to work 11 stations across the continental USA and Mexico. After the pass, I went to get lunch and then return to this area - to find a better spot on the DM26/DM36 boundary before the next AO-27 pass. Monday (21 July) afternoon, from grids DM26xt and DM36at in Scenic AZ: http://maps.google.com/maps?f=q&hl=en&geocode=&q=36+48.020+n+114+0.00+w&ie=… Before the later AO-27 pass to the west, I found this spot on the DM26/DM36 grid boundary east of the Arizona/Nevada state line. I could find a spot and not worry about the mountains to the east, and still put DM36 on the air one more time before heading down the I-15 freeway to Las Vegas. I set up my station, and proceeded to work 9 stations from central Mexico to western Canada during this 7-minute pass. A total of 27 contacts from 3 different locations in DM36 today. Not bad. On to Las Vegas... Monday (21 July) evening and Tuesday (22 July) morning, from DM25jx and DM26ja in Las Vegas NV: http://maps.google.com/maps?f=q&hl=en&geocode=&q=36+0.00+n+115+10.230+w&ie=… Before this trip, I looked at maps and saw the DM25/DM26 grid boundary passed through the south side of the Las Vegas metropolitan area. This would be a good way to put the unusual DM25 grid on the air along with the more-common DM26 grid. Along this part of the Las Vegas Strip (Las Vegas Blvd.), there were lots of empty spaces. Perfect places to set up for satellite passes. I drove less today, covering over 345 miles/556km from Lake Powell to Las Vegas - still a lot of driving in one day with the stops. Once I found this spot, I set up for the first of 2 AO-51 passes this evening (0122 UTC Tuesday). I was ready, and the activity was steady throughout the pass. I logged contacts with 22 different stations from central Mexico to western Canada on this pass! Again, thanks to all who were on that pass for making this a very successful effort - and more contacts on one pass than I've ever worked before. Later in the evening, I worked the western AO-51 pass from the same spot starting at 0302 UTC. After hearing a couple of stations who did not respond to my calls, I worked 8 other stations. I was able to work an SO-50 pass Tuesday morning just after 1700 UTC before leaving Las Vegas, logging just 2 contacts. A total of 32 contacts during 3 passes from DM25/DM26 - a very good show! Tuesday (22 July) afternoon, from DM24qx and DM25qa in Camp Mohave AZ: http://maps.google.com/maps?f=q&hl=en&geocode=&q=35+0.00+n+114+35.610+w&ie=… This was my last day on the road, and I wanted to try for grid DM24 at least once. Time permitting, and depending how I felt, I hoped to also try for possibly grid DM23. There was an overhead AO-27 pass this afternoon, and I decided to drive south from Las Vegas to this area along the Arizona (east) side of the Colorado River, south of the cities of Laughlin NV and Bullhead City AZ in Mohave County. Despite the mountains on both sides of the Colorado River, I had a good view of the sky in all directions. The AO-27 pass I intended to work was another virtually overhead pass. I parked my truck to shade me as much as possible from the 107F/42C heat, and prepared for the pass. When the AO-27 repeater switched on at 2149 UTC, I went to work. Again working stations from central Mexico to western Canada, I logged 15 contacts in the first 5 minutes of the 7-minute pass. I may sound like a broken record by now, but I have to thank the other stations on that pass for allowing so many quick contacts to happen in the limited time on AO-27. After this pass, I decided to end my radio operating and just drive home. I still had about 4 hours to go before returning to Phoenix, and with the sun still getting warmer as the afternoon went on... I decided to disassemble my Yagi and pack everything up for the drive home (247.5 miles/398km from Camp Mohave to Phoenix). ********** During my trip, there were stations who worked me from many of the grids I stopped in. Here's a summary of the callsigns I worked from the most grids while I was on the road... All 10 grids: K7RST, W6ASL, W6ZQ, XE1AO 9 grids: N3TL, WA4NVM 8 grids: N5AFV, XE2RV 7 grids: KD8CAO 6 grids: VE7JRX, W5VG, XE1BMG, XE2BHL 5 grids: KE7SAK, VA7VW, WA4SCA, WA8SME, XE2YW Even though the price of fuel was high - prices from $3.959/gallon ($1.046/liter) in western Arizona up to $5.19/gallon ($1.374/liter) in Needles CA near the borders of Nevada and Arizona - I was able to cover this distance and not single-handedly prop up some of the oil- producing countries. I had a $50 Shell gift card I won at my office, that was used during this trip - plus good performance from my vehicle on the open road. When I returned home, I had already received some QSL requests. I will get some cards printed for each stop on my trip, and I should have them soon. 73! Patrick WD9EWK/VA7EWK http://www.wd9ewk.net/

AO51/GO32 Mobile Manual Tracking Table updated
by Robert Bruninga 29 Jul '08

29 Jul '08

The AO51 mobile tracking table only has 5 entries because the pass times repeat every 5 days so it can be reduced to a single table good for 2 months like this: EASTERN Daylight Time AO-51 01Aug 07Aug 13Aug 19Aug 25Aug ----- ----- ----- ----- ----- 0800 0855 0815 0740 0835 0935 0920 1910 2010 1930 1850 1950 2030 Cut/paste on your dashboard or shack bench. The table is good for a month or two and allows you to always estimate satellite passes within 5 minutes. You don't need no stinking PC for 2 months. These are the peak passes for your time zone. If one peak pass is shown, then there are two other lower passes 100 minutes earlier and later. If two modest passes are shown, then the others will probably be too low. TO use this on any day, just find the column nearest todays date and count forward or backward the number of days. SO for today (July 29th), start on 1 Aug and count (rotate) to the left 3 days. So tonight's pass will be at 1930 (and one at 1750 and 2110 ish) I updated the tables for both birds and each USA time zone on my Mobile Manual Tracking web page: http://www.ew.usna.edu/~bruninga/MobileLEOtracking.html There are other hints there that allow you to be more accurate based on where you live in your time zone, etc. The table for the GO32 APRS satellite repeats every 9 days and is good for 3 months or so: EASTERN Daylight Time 01Aug 11Aug 21Aug 31Aug 10Sep 20Sep 30Sep 10Oct 20Oct ----- ----- ----- ----- ----- ----- ----- ----- ----- 0920 0855 0835 0810 0930 0905 0845 0820 0940 1015 0950 1025 1000 2035 2015 1955 1930 2005 2025 2005 1940 1920 2135 2110 2120 2100 If you get bored on your daily commute and want to see what the satellites are doing and you are on the road during these times, you don't need a PC. Just look at your dashboard, do a little mental processing, and bingo, you can estimate the next pass easily. Bob, WB4APR
