My 6-7 June road trip, lots of miles & grids - report

Hi! I'm a little tardy in sending this e-mail out, but wanted to post a report on my road trip to northern Arizona and southern Utah on the weekend of 6-7 June. After over 1100 miles in just over two days, I had fun hosting an AMSAT table at a hamfest, followed by a lot of driving and operating. I made the 3-hour drive up to Show Low, in eastern Arizona the night before the White Mountain Hamfest on 6 June. I drove through rain and some fog up to Show Low, which made the morning a little cooler. A nice crowd showed up for the half-day hamfest, and WD9EWK was on a couple of SO-50 passes followed by an AO-73 pass during the morning. The hamfest was located in grid DM44xg, near the Show Low city hall and the US-60/AZ-260 junction. By 11.30am (1830 UTC), the hamfest was wrapping up. This gave me about 2 hours to get to the first post-hamfest stop of this road trip - the DM54bx/DM55ba grid boundary, along old US-66 and I-40, about an hour north of the hamfest site. The DM54bx/DM55ba grid boundary is a place I have worked from several times in the past few years, most recently in June 2014 after the same hamfest. I planned to work AO-7 and FO-29 from here, so I could get these two grids on the air. The AO-7 pass came first, and I was able to make two SSB QSOs before the satellite was forced from mode B to mode A (thanks KG5CCI & N4UFO!). It is unfortunate that stations still insist on running lots of power when working AO-7, in SSB and especially CW. FO-29 came by a few minutes later, and that was better. Three more stations went in the log on that pass, then it was time to hit the road again. I had received requests to work from grid DM45 during this weekend, and I was able to do that for the later AO-7 and FO-29 passes. I drove about 50 miles/80km west on I-40 to Winslow, near the southeast corner of grid DM45. After making a stop at "the corner in Winslow, Arizona" for some pictures, I drove east to the end of old US-66 and parked in front of an old trading post to work AO-7 and FO-29 from here. These two passes were both almost directly overhead for this location, and this time AO-7 stayed in mode B for the entire pass. Five stations were logged on AO-7, and six more on FO-29. >From Winslow, I drove about 60 miles/100km west to Flagstaff for dinner and fuel, before turning north on US-89 to Page and Lake Powell, at the Arizona/Utah state line. For the drive between Flagstaff and Page, I stopped at two points to work ISS passes. The first stop was north of Flagstaff, still in grid DM45, around 0115 UTC. No QSOs were logged, although I saw several stations on my TH-D72A's display. After that pass, I kept going north on US-89 onto the Navajo Nation reservation. As the last glimmer of sunlight was about to disappear from the western sky, I made another stop at the US-89/US-89A junction near Page just before 0300 UTC. This was at grid DM46ep, with a nice view to the west for this ISS pass. I exchanged APRS messages with KK6RKY in northern California, saw a few other stations, then went back onto US-89 to finish my drive to Page. Once in Page, I stopped in a Wal-Mart parking lot along US-89 to work an AO-73 pass just before 0400 UTC. This was in grid DM46gv, a few miles/km south of Lake Powell, Glen Canyon Dam, and the Arizona/Utah state line. Since it was getting late, and I needed to leave Page early the next morning, I only worked one pass. Six in the log, and that ended my Saturday. As the sun was rising Sunday (7 June) morning, I left Page to reach the DM47xb/DM57ab grid boundary in southern Utah. This was a 130-mile/210km drive, and even with two stops for caffeine on the way I made it to the spot with about 30 minutes to spare. I had operated from this spot in 2009, on a county road southeast of US-163 in San Juan County. This area is also on the Navajo Nation reservation, and north of Monument Valley. After taking the obligatory photos of my station and GPS receiver, I was ready to work an SO-50 pass followed by an AO-73 pass between 1510 and 1550 UTC. Other than making another trip to this part of the country, I had heard from Drew KO4MA that DM47 and DM57 were two of the three grids in this part of the US he did not have confirmed via satellite. Others had also mentioned they either needed one of these grids, or both of them as well. The SO-50 pass was great for working stations from coast to coast. A total of 16 stations, including KO4MA, were logged. The AO-73 pass around 1545 UTC was a very low pass out there, with a maximum elevation of 4 degrees to the east. Despite that, I logged QSOs with AC0RA and K4FEG. Before the western SO-50 and AO-73 passes after 1700 UTC, I drove back to US-163 and stopped at a spot with a great view to the south and Monument Valley. I took lots of pictures out here, and some of those were sent out via Twitter for those who were watching me that morning. After spending most of the 1600 UTC hour sightseeing, I drove back to the DM47/DM57 boundary for the last two passes I'd work out there. Six stations logged on SO-50, followed by 3 on AO-73, to wrap up the DM47/DM57 part of this road trip. Another grid boundary I looked to work from on this trip was the DM56/DM57 boundary, a place I worked from in 2008. This is along the US-191 highway, just north of the Arizona/Utah state line. It was about 75 miles/120km from the DM47/DM57 boundary just off US-163 to the DM56ex/DM57ea boundary on US-191. With a lunch stop along the way, I made it to the spot with about 20 minutes to spare. I planned to work two AO-7 passes and one FO-29 pass, along with the obligatory grid-boundary photography, before making the drive home (almost 6 hours!). The first AO-7 pass around 1930 UTC was not too high, but high enough to be able to hear myself for almost the entire pass. I logged only one QSO, with John K8YSE, near my LOS. Then an hour or so of sightseeing up US-191 and back, before the better AO-7 and FO-29 passes starting around 2125 UTC. The two later passes were productive. I logged 7 QSOs on the AO-7 pass, and 10 QSOs on the FO-29 pass after that. When I was up here in 2008 and 2009, I only worked FM passes. With SO-50 only passing by in the mornings, working the SSB birds was mandatory on this trip up here. When I wasn't trying to work the ISS passes, I left my TH-D72A squawking my location as WD9EWK-9 on this trip. I did not use APRS when I was up there in 2008 or 2009, and I hoped that mountaintop digipeaters would hear me. A few in Utah and Colorado did, and I was able to see myself later on aprs.fi. Some areas were not covered, in particular the two grid boundaries I stopped at in southern Utah, but the highways mostly had good coverage. I could use an app on my mobile phone, but prefer to use APRS with RF. The mobile phone network on the Navajo Nation was dramatically improved since 2009. I had high-speed data access while I was out there, which let me send photos via Twitter and see how well my APRS signals were making it to the Internet. After the trip, I uploaded my log to Logbook of the World. Over half of my 89 QSOs from this trip have been confirmed via LOTW. This is nice to see! I am also planning to print some QSL cards this weekend, to answer some QSL requests that have landed at my PO box. Again, it's not necessary to send me your QSL card or an SASE when you work me on my road trips. An e-mail with the QSO details is sufficient. If you're in the log, I will put a card in the mail to you. If you work me when I'm at home, or near the Phoenix area (in general, when I'm in grids DM33 and/or DM43), then I would appreciate receiving your QSL card. I drove 1145 miles/1843km in just over 50 hours on this trip, and operated from 8 different grid locators in Arizona and Utah (DM44-47, DM54-57) - including 3 grid boundaries (DM47/DM57, DM54/DM55, DM56/DM57). Other than my long drive from the ARRL Centennial Convention in Hartford last year up to northern Maine, it has been a while since I have done a trip like this. It is fun to mix in satellite operating on trips, and I hope to do more of this in the remainder of 2015. 73! Patrick WD9EWK/VA7EWK http://www.wd9ewk.net/ Twitter: @WD9EWK

NanosatC-BR1
by Edson W. R. Pereira 16 Jun '15

16 Jun '15

Hello everyone, The first Brazilian cubesat, NanosatC-BR1, is experiencing battery issues for the last several months and it now seldom emits a beacon in CW. For some time, Paulo PV8DX, was able to detect a beacon signal when the satellite was over the Caribbean sea during daylight. But now, no more signals have been detected. We would like to request assistance from hams in the northern hemisphere to see if NanosatC-BR1 is still transmitting any signals. Any help will be much appreciated. 73, Edson PY2SDR --- - We humans have the capability to do amazing things if we work together. - Nós seres humanos temos a capacidade de fazer coisas incríveis se trabalharmos juntos.

Re: [amsat-bb] Tropo and FO-29
by Kevin M 16 Jun '15

I also heard the '1, 2, 3, 4, 5' clearly, well after your LOS according to the tracker. W4UOO was trying to call you, I believe. I've also been noticing that I will hear FO-29 BEFORE AOS as well on some of these passes lately. -- Not tropo, but talk about working over the horizon... ever work RS-12/13?!!! When in Mode K (15m up and 10m down) you could work a pass from another continent! Biggest shock I ever had was calling CQ with the bird descending over North America (LEO) and getting a call from OK1DIG. =^D There was an article in QST about an op who worked DXCC on RS-12/13 by using this method. Boy, I miss that bird. 73, Kevin N4UFO (ex-AC5DK for any other RS-12/13 ops out there)

kepler data of AO-73 and Ham Radio Deluxe next pass info
by Peter Kaminski 16 Jun '15

16 Jun '15

Hello, today I received some telemetry frames of FUNcube-1 AO-73 but as I checked the pass in Ham Radio Deluxe Sat Tracking I saw that the next pass should be in abt. 10 min. later. So I manually reload the Kepler data from www.amsat.org/amsat/ftp/keps/current/nasabare.txt but always there is a big difference between the real pass of AO-73 and the passes shown in HRD. I use the latest update of HRD (updating a few days ago). So do anyone has the same problem? May be something happend in the HRD update? The URL of the kepler data is OK because I can finde the file on the amsat server via the link. Any idea? May be I should try another kepler data source? regards Peter DL9DAK | N9DAK -- DL9DAK | N9DAK Peter Kaminski Vogt-Wells-Str. 5 22529 Hamburg Germany phone: +49 40 41477811 mobile: +49 172 4053333 skype: peter.kaminski.hh email: info(a)dl9dak.de web: www.dl9dak.de

2111Z from VP2MKV
by Jim White 15 Jun '15

15 Jun '15

Interesting propagation. We heard ourselves for about 3 or 4 minutes but there were deep fades about every 10 seconds. We suspect constructive/destructive interference from the over-water path. But we never heard another signal. We will not be on tomorrow but should be on Weds and Thursday. Jim

I also meant to add, it was very noticeable when I was operating as VP2EAG from Anguilla, both with the Arrow and HT on UO-14 (sobsob) and with the dish on AO-40 S-band. The first pass on AO-40 was from a hill on the island, with the 18" DSS dish upside down on the windshield/hood to get down to the 6 degree elevation the sat was to the west. I noticed a big signal bump approaching the horizon, and a bit past my predicted LOS, even on 2.4 GHz. Great memories of that, and working from neighboring islands on AO-27 and UO-14, and running dozens of EU stations at 3AM on U/S, even split, spreading them out over 20-30 kHz. 73, Drew KO4MA
