Upcoming ARISS contact with King Island District High School, Currie, TAS, Australia
by n4csitwo＠bellsouth.net 18 Jun '19

18 Jun '19

An International Space Station school contact has been planned with participants at King Island District High School, Currie, TAS, Australia on 19 June. The event is scheduled to begin at approximately 08:49 UTC. It is recommended that you start listening approximately 10 minutes before this time. The duration of the contact is approximately 9 minutes and 30 seconds. The contact will be a telebridge between OR4ISS and IK1SLD. The contact should be audible over Italy and adjacent areas. Interested parties are invited to listen in on the 145.80 MHz downlink. The contact is expected to be conducted in English. King Island District High School is located in the Bass Strait off the North West Coast of Tasmania. We cater for approximately 210 students from Kinder to Year 10. Our school is at the heart of our community, we value each student and their family. We have been striving to create resilient, innovative lifelong learners; our school has been on a learning journey with Literacy and Numeracy as our core fundamentals. Our students have the opportunities for on-island and off-island camps from Year 3 and up, we participate in sporting events in mainland Tasmania, we have students from Kinder to Year 10 being able to access specialist Music and Art lessons. We are grateful to have a well resourced MDT room, Computer Lab, kitchen which has then eventuated into a school café 'The Rock Café', which offers café style lunches, drinks and monthly dinners to our community giving our students first-hand experience of hospitality. We are also in the process of building our own golf hole to fit in with the islands golfing influx of late. Participants will ask as many of the following questions as time allows: 1. Why did you become an astronaut? 2. What training do you need to be an astronaut to go to space and where did you do your training? 3. What sort of food do you eat and how do you determine your meal times in space? 4. What do you do in your spare time so you don't get bored while in space? 5. Does it get lonely in space? 6. How do you exercise in space? 7. How old is the International Space Station and do parts wear out in space like they do on earth? 8. What is your job on the ISS and how do you do it? 9. What are space worms and why are they so important in space? 10. How long does it take to orbit the earth? 11. Have you researched the black hole and if so, how big is it? 12. What kind of research do you do? 13. Do you have any advice for any of our students wishing to follow in your career path?

Fixed elevation - how many elements?
by Martin Cooper 17 Jun '19

17 Jun '19

I'm contemplating building a couple of yagis, possibly even crossed ones, and putting them up at fixed elevation (i.e. az-only rotator). What I'm unclear about is how many elements to consider. My location is really pretty dreadful for seeing sky. There's a big hill to the NE that restricts me to above 40 degrees in that direction. I'm in a single-storey house, with neighbouring two-storey houses to the NW, SW, and S. In between all that, there are other single-storey houses, and trees in most of the gaps between houses. I can't afford to put up a tower (and it could never get above the hill anyway), so I'm looking at not too much above my roofline. To at least get through the trees, I'd think more elements would be better. But more elements narrows the beam, and at fixed elevation, that, at some point, will restrict even further how much of the sky I can play with. I'm looking for thoughts on how many elements would be recommended, and how many would be too many, for a fixed elevation, both for VHF and UHF. Ultimately, I'd like to be able to get on the linears, so not limited to the FM sats. Any thoughts would be much appreciated. Thanks in advance. Martin. KD6YAM

Quads on the satellites
by John Geiger 17 Jun '19

17 Jun '19

Has anyone tried the Cubix dualband quad on the satellites? I am wondering (hoping) that it might have a better elevation pattern than my Cushcraft A270-10S dualband yagi does. On Mode B passes, the satellite has to get to a 25 degree elevation or more before I really have a good chance at getting into the FM satellites. It would be nice to have something that allowed for better success at the lower elevations also. 73 John W5TD (ex AF5CC)

HS10KING on QO-100
by Tanan Rangseeprom 17 Jun '19

17 Jun '19

Dear AMSAT member, To strengthen the relationship between Thai and Japanese amateur radio operators representatives of the JAMSAT group of Japan have travelled to Thailand to visit the satellite ground station HS0AJ and will operate from the Ground Station of the Radio Amateur Society of Thailand under the patronage of His Majesty the King (RAST). On the occasion of the coronation of His Majesty King Vajiralongkorn Bodindradebayavarangkun, HS10A (pronounced "Hotel Sierra-TEN-Alpha), as the 10th king to reign in the Chakri Dynasty, the National Broadcasting and Telecommunications Commission (NBTC), Thailand's regulator, has authorized the special callsign HS10KING (pronounced "Hotel Sierra-TEN-KING). There will be an opportunity to communicate with HS10KING using the QO-100 amateur radio satellite and low earth orbit (LEO) satellites that windows pass over Thailand by amateur radio stations which is similar to AMSAT Germany's use of the special callsign DL50AMSAT using the QO-100 satellite. RAST hence invites AMSAT amateur radio satellite operators to join in contacting the HS10KING special event station from June 22, 2019 at 10.00 UTC (17.00 Thailand time) until June 23, 2019 at 10.00 UTC (17.00 Thailand time) using SSB mode and DATV (333 - 250 KS) signals from the station HS10KING. Please be informed and let others know of this opportunity. Sincerely and with respect, de HS1JAN Tanan Rangseeprom Project Manager of JAISAT-1

AO-85 report from the 2019-06-16 - 0028 UTC pass
by John Brier 17 Jun '19

17 Jun '19

Hi, I made five QSOs on this 47 degree pass from FM05. I was using my Kenwood TM-V71 radio at 50 watts and an Alaskan Arrow II antenna with the last third boom section removed. I didn't hear the bird for the first couple minutes of the pass and couldn't get it to come on myself. Eventually it came on and I heard Clayton W5PFG not long after that so I assume he turned the transponder on. In the first half of the pass it was difficult to get a solid signal into the sat. Other stations had the same problems. Audio was sometimes really low, great other times, and distorted at times as well. The last part of the pass was not bad though. I was able to consistently get a signal into the bird, even at 10 or 5 watts. I had a conversation with Roy K3RLD about this as we were both having the same good luck. This reminded me of past AO-85 behavior where it is easier to get in in the last part of the pass. I was actually on top of a landfill park in my town so I had a perfect view of the horizon and was able to get in all the way to LOS, albeit with some picket fencing effects on the downlink. Stations contacted: W5PFG W5HRH N9XCO * N0RC K3RLD Also heard ???PML * This was Richard N9XCO's first sat QSO. He just finished setting up a IC-9700/G-5500/SatPC32 station One odd thing I noticed is at the end of the pass I believe I was at 145.970 MHz, 10 KHz down from the center frequency of 145.980. It looked so weird I did a double take and doubted I was really at that frequency. I don't know if the bird was off frequency or if it was something on my end. My audio recording is here: https://www.dropbox.com/s/j1xduj3had9gicm/2019-06-16_0028_UTC_AO-85_KG4AKV_… 73, John Brier KG4AKV

Recent rove by N6DNM in DN00/10, DN20/30, DN41/51, DM79, DM58/59, DM48/49 grids
by Dmitry Mizin 17 Jun '19

17 Jun '19

Hello, Thank You for chasing me on my recent trip from above grids and mostly gridlines. I have uploaded (and corrected some) all entries into LOTW. I am sure I still have made a few mistakes with entries - so, if you worked me between 20190606 and 20190615 when I was in those gridline(s) and do not see a LOTW confirmation - please let me know. There were two undecipherable entries in my audio recordings from DM58/59 and DM48/49 both on SO-50 - if you are one of them, please let me know and I will review my recordings again. Once confirmed - will upload corrected entries. Thank you all again! It was a blast as this was my first "big" trip doing those activations. There will be more coming soon. Dmitry Mizin, N6DNM

input power question
by mikflathead＠aol.com 16 Jun '19

16 Jun '19

I have completed my sat station but am having trouble hearing myself. I have checked cables and antenna ( M2) sat antenna. All seems well with low SWR. I can hear on the 2 meter downlink. How much power is needed on the UHF uplink? Hope to figure this out shortly. This is being done on the SSB sats. Thanks Mike WB8PFZ
