Re: [amsat-bb] KG-UV8D
by Patrick STODDARD (WD9EWK/VA7EWK) 27 Nov '16

27 Nov '16

Hi! I don't have a KG file to share, but those should not be shared between radios anyway. Those files are not like the config files used in the "normal" ham radios like you get from Icom, Kenwood, and Yaesu. But I can offer some suggestions and advice... The KG-UV8D is not capable of working SO-50 full-duplex. When you transmit on 2m, the 70cm receiver is desensed. You won't hear the satellite again until you stop transmitting. The radio is capable of working AO-85 full-duplex. I wrote about this on the AMSAT-BB list a year ago, and you can see that message at: http://amsat.org/pipermail/amsat-bb/2015-November/056254.html I do not use memory channels for working AO-85. I use the two VFOs, open the squelch all the way for the receive VFO, and transmit from the other VFO. That link has some key settings I used with that radio. You can program a group of memory channels to work SO-50 half- duplex. A guide for that is available from AMSAT's Station and Operating Hints page at: http://www.amsat.org/?page_id=2144 (look for the document "Operating FM Satellites") Or use another HT with your KG-UV8D, so you can transmit from one radio while listening to the other radio for full-duplex operation. If you want to use an HT to work both AO-85 and SO-50 full-duplex, there is only one option currently in production: Kenwood TH-D72A. The new TH-D74A is not capable of full-duplex operation for any FM satellite. Wouxun's KG-UV9D, like the KG-UV8D, is capable of working AO-85 full-duplex, but not SO-50. Along with the KG-UV8D, I wrote about a few other Chinese-made HTs and tried using them to work FM satellites full-duplex. They could do that with AO-85, but not SO-50. You can get to the messages covering the other radios I wrote about at: http://amsat.org/pipermail/amsat-bb/2015-December/056269.html 73!

ISS Packet Format
by Gerald Payton 27 Nov '16

27 Nov '16

I just finished reading JoAnne Maepaa's (K9JKM) excellent PDF on ISS packet operation. Thank you JoAnne. Couple of questions, please: 1) What "Terminal Emulator" do members use? 2) Looking at the examples in her PDF I noticed "qAR and qAS." What are these terms? It has been at least 10 years since my brush with packet. I have to really REBOOT my brain, for sure. Thank you & 73, Jerry AB5R

How to avoid Black Friday, working satellites... (long)
by Patrick STODDARD (WD9EWK/VA7EWK) 27 Nov '16

27 Nov '16

Hi! On Friday (25 November), I didn't want to stay home. I wasn't going to visit stores or shopping malls, where I'd have to deal with crowds on "Black Friday". With decent weather throughout Arizona, and especially no snow on the highways in northern Arizona, I made a quick road trip to operate from some rarely-heard grids. I also wanted to operate from a national monument for another National Parks on the Air activation. Even with the cool weather in northern Arizona, it was a fun day to work satellites and do some sightseeing before the snow arrives. I had originally planned to visit the Walnut Canyon National Monument, east of Flagstaff along the I-40 freeway. I had been to this site in June, trying to make a NPOTA activation then. I came up short of the minimum number of stations I needed to work for an official activation (10), but wanted to rectify that before the end of the year. Walnut Canyon National Monument is in grid DM45, a rarely-heard grid on the satellites, so a trip up there would satisfy operators on two fronts. Then Steve N9IP mentioned on Twitter earlier in the week that he needed grid DM44. I started looking at pass predictions, trying to see how I could work a stop in grid DM44 along with working at least a few passes from Walnut Canyon. Seeing that SO-50 would pass by in the morning, and not be available later in the day at Walnut Canyon, I planned an early stop in DM44 to make this happen. After waking up to a 5am (1200 UTC) alarm clock, I was on the road by 1245 UTC. The first SO-50 pass was due to pass by around 1418 UTC, and I could be in DM44 at a point about halfway up the I-17 freeway between Phoenix and Flagstaff. With some hills to the east in this area, the best spot to work from DM44 was actually on the DM34/DM44 grid boundary, on a wide shoulder next to Cherry Road (AZ-169), just west of I-17. I had about 20 minutes to find the spot I wanted to use, document my location with photos, and set up for the SO-50 pass. I did all of that, tweeted photos showing my location, and I was ready for SO-50. I also had to change from a light windbreaker to a heavier jacket, as the temperature was around 43F/6C at the start of the pass with a stiff breeze. The 1418 UTC SO-50 pass was a 16-degree pass to the northeast. Once I heard the downlink, I started working stations across the USA, along with Canada and Mexico. I have operated from both DM34 and DM44 earlier in the year, but there is almost always someone looking for either of these grids - or both of them. N9IP was the fourth of the 13 stations I worked during this pass. After LOS, I quickly put the radio and antenna back in my car, so I could finish my drive up to Walnut Canyon. When I arrived at Walnut Canyon, I went to the same spot I used in June. I parked just off the main road between the I-40 freeway and the visitor center on the edge of the canyon. The national monument includes a strip of land that connects the visitor center to the freeway, and the spot I used has a Forest Service road that cuts through the national monument about a mile north of the visitor center. It is also at 6600'/2011m, and a bit cooler than it was at the DM34/DM44 grid boundary that was just over 4400'/1341m elevation. The temperature was down to 26F/-3C, something I rarely see in the Phoenix area. The heavy jacket I put on for the earlier stop was definitely necessary here. The first pass I worked from Walnut Canyon was a western SO-50 pass just before 1600 UTC. This was a surprisingly busy pass, with 13 stations worked - an official NPOTA activation, just with one pass! I didn't stop with this pass. A few minutes after SO-50 went away, FO-29 came up a few degrees to my east. The satellite went up to a maximum elevation of 8.6 degrees. Even with the low elevation, and trees around my location, I logged 3 QSOs. During the week leading up to this trip to Walnut Canyon, the 145.825 MHz packet digipeater on NO-84 had been turned on. It was still on while I was at Walnut Canyon, and made use of it. The first of two NO-84 passes was a 28-degree pass. NO-84's digipeater has a weaker downlink than what we used to hear from the ISS on the same frequency, so it is more of a challenge to make QSOs. Fernando NP4JV and I made what was my only QSO on this pass, near my LOS. About an hour later, there was another pair of passes - FO-29, followed by NO-84. It was also starting to warm up - the temperature went above freezing, up to 37F/3C. This time, just before 1800 UTC, FO-29 was passing very high over northern Arizona. I was able to work 7 stations from coast to coast in the continental USA, and one Canadian station. The NO-84 pass around 1820 UTC had a little more activity. I was able to work both KG6FIY and KK6OTJ in southern California via APRS messages. Thanks Endaf and Mark for those QSOs! For these trips, working the orbiting packet digipeaters is just another satellite or two, and it was fun to have a total of 3 QSOs via NO-84 from Walnut Canyon. By midday (1900 UTC), the outside temperature had made it up to a comfortable 53F/12C. The heavy jacket went in the car, and I put my windbreaker on instead. I had two more passes I planned to work, one more FO-29 pass at 1935 UTC followed by AO-85 just after 2000 UTC, before heading to Flagstaff for lunch and the drive home. The 1935 UTC FO-29 pass favored the west coast, and I worked just 2 stations. The AO-85 pass just after 2000 UTC passed across the continental USA, making for a busier pass. I worked 10 stations from coast to coast, including AI6GS who was also at an NPOTA site in southern California (Joshua Tree National Park). This pass would have made an NPOTA activation by itself, and it has been fun to make park-to-park QSOs during this year. After AO-85 went away, I packed up for the drive to Flagstaff for lunch, and then the drive home. It was a nice day to be in northern Arizona, as there should be snow falling up there today or tomorrow - and I don't like driving in northern Arizona snow. Road conditions were good all day, even for the drive up in the morning with below freezing temperatures. The only snow I saw was on the tops of the San Francisco Peaks that overlook Flagstaff, and that's OK with me. :-) I made a total of 38 QSOs from Walnut Canyon National Monument: 13 QSOs on the SO-50 pass, 12 QSOs across 3 FO-29 passes, 3 QSOs on 2 NO-84 passes, and 10 QSOs on the AO-85 pass to wrap up this NPOTA activation. Along with the 13 QSOs made from the DM34/DM44 line earlier, a good day to be on the satellites. All of the QSOs I made from the DM34/DM44 grid boundary, as well as those made at Walnut Canyon, are in Logbook of the World. If anyone who worked me wants a QSL card, please e-mail me directly with the QSO details. If you're in my log, I'll send you a card. No card or SASE required. Working from rarely-heard grids is always fun, and NPOTA has added to that in 2016. I still hope to make it to one or two other NPOTA sites in the last few weeks of the year. 73!

Saturday night fun with 70cm ISS packet
by Patrick STODDARD (WD9EWK/VA7EWK) 27 Nov '16

27 Nov '16

Hi! With the recent change to the UHF radio for the ISS packet digipeater, this has disappointed some - and made others happy. I enjoyed working stations through the 145.825 MHz digipeater, but working packet on 437.550 MHz has been fun, and bringing new challenges. Last night, with 3 ISS passes over Arizona, was a great time for that... The first of the 3 passes came just before 0130 UTC. Using my TH-D74A HT and Elk handheld log periodic, I was able to get my position packets retransmitted on this 9.9-degree pass to the southeast. Unfortunately, I made no QSOs, and only heard one other station being retransmitted before my LOS. Although this pass was a bust in terms of adding to my logbook, the next couple of passes would be more successful. On to the 0300 UTC pass... The second of the three evening passes saw the ISS rise higher, to a maximum elevation of just under 55 degrees. For those in California, this was basically an overhead pass. After I worked a station on a similar pass using my TH-D74A and a Diamond RH77CA long duckie antenna just over a week ago, Mark KK6OTJ in southern California mentioned that he wanted to try for a QSO where both of us use an HT and long duckie. I suggested that this pass could work for us, and we went for it. Mark has a TH-D72A HT, a BNC-to-SMA adapter on his radio, and a Diamond RH77CA duckie antenna. Other than the radio, we had the same setup on each end to make this attempt. With the ISS coming up from the southwest, I thought we would have the best chance to make this QSO earlier in the pass, certainly before the midpoint of the pass. I prepared an APRS message for Mark's KK6OTJ-7 packet call sign with the text, "HT/duckie in DM43. QSL?" This is what I started sending, once the ISS was up from the horizon. Watching the clock and the AmsatDroid Free tracking app on my mobile phone, we went through the first 5 minutes of the pass with nothing. Still sending my APRS message with my grid locator, I saw an ACK come through the ISS digipeater around 0307 UTC. Mark received my message, and his TH-D72A sent an acknowledgement back to my TH-D74A. This was quickly followed by Mark's APRS message, "QSL, Thanks & 73!" I sent a final "rgr" back to Mark, completing the exchange and the QSO. After the pass, Mark sent a photo of his TH-D72A's screen showing my APRS message, and wondering if I had received his message. Apparently, my radio's ACK for receiving his message didn't make it through the ISS digipeater, but I had received his message. I tweeted a reply, showing a listing of the messages - my message to him, then his message to me, and the final message I sent him - along with a screenshot of each message from that listing. Thanks for the QSO, Mark, and for the challenge to do this. After that high pass, there was still one more pass to work around 0440 UTC. Like the first pass of the evening, this was another shallow pass - maximum elevation of just under 9 degrees, but to the northwest. I was hoping to hear Kevin VE6QO in southern Alberta on that pass, and maybe make a QSO with him. Kevin has been trying to work stations, but the passes weren't helping me make a QSO. I have a line of thick trees north of my house, which acts like a wall for the 437.550 MHz signals. I went back to my Elk log periodic for this pass, knowing that the Diamond duckie would not be a good antenna for a shallow pass. If I was able to make an exchange with Kevin before the ISS was north of me, it might be possible. And that's what we did... I started sending my position packets once the ISS rose above the houses west of me. I could see those packets being digipeated, and then I saw "VE6QO" show up on the top of my TH-D74A's display. I knew Kevin was there, even though his position wasn't being transmitted. I made a very short APRS message to him - "dm43", my grid locator - and started to send that. Kevin was also trying to send me his grid locator, but the low pass was making this tough. While this was happening, I saw two other stations showing up on my screen - VA7THO in British Columbia, and W0JW in Iowa. Kevin and I kept at it, and finally I saw my "dm43" APRS message being retransmitted. After that, I saw "TU and 73" come from Kevin's end. I followed that up with a "73" to complete our QSO. Thanks again, Kevin, for the QSO! More stations are starting to find their way over to the 437.550 MHz ISS digipeater. Unfortunately, this also includes the unattended beacons that were all too common on 145.825 MHz. It appears we will have ISS packet on 70cm for a while, given that a radio capable of VHF packet may not be sent to the ISS until late next year. For many FM transceivers capable of packet operation, using a group of 5 memory channels to compensate for Doppler is the ticket to being successful working packet on 70cm. Think of working the 70cm ISS packet digipeater like the combination of AO-85's uplink and SO-50's downlink, all on one frequency. The uplink frequency moves up as the downlink frequency moves down, and near the middle of the pass the two frequencies are the same. I posted on this list and tweeted the chart I used for programming my HTs to work the 437.550 MHz digipeater. That chart is also available from You can get to the chart with this direct link: http://www.amsat.org/wordpress/wp-content/uploads/2014/01/ISS _Packet_Operation_on_70cm-20161113.pdf This document, along with K9JKM's guide on ISS packet operation and more, is available from AMSAT's Station and Operating Hints page: http://www.amsat.org/?page_id=2144 If you previously worked the ISS packet digipeater on 145.825 MHz, working the 437.550 MHz is not that different. Dealing with Doppler is a must, and the higher frequency could lead to issues if your QTH has trees in the way of your antenna(s), but there are stations looking to do more than transmit beacons automatically. If you would like to attempt a QSO with me using the 70cm ISS packet digipeater, please e-mail me directly. There should be some options for QSOs with stations across much of the continental USA, as well as with many parts of Canada and Mexico. 73!
