I will be driving to Newport OR tomorrow June 7th and will try to stop for AO-91 in CN86 (maybe CN85 depending on traffic) at 13:12 local 2012 UTC. I will stop in Newport CN74 over night and on Saturday June 8th and I will try AO-91 at 11:57 local 1857 UTC and then AO-92 at 12:08 1908 UTC. This all depends on how the swap meet is going, cause I'm selling. Friday evening I will be at Yaquina Head Light USA-907 for those who also do lights. Most likely I be around 14.335 KHz. John N7AME

Doppler shift question
by David Bartholomew 06 Jun '19

06 Jun '19

I am composing a presentation about FM sats, hopefully to be given in a few months at a hamfest. How to remember which way to compensate for doppler: Always adjust the higher frequency. For V/u or U/v sats, this means adjust the 70cm side and leave the 2m side fixed. Which way to move it? Very easy to remember. If 70cm is the UPlink, you'll adjust your transmit frequency UPward through the pass. If 70cm is the DOWNlink, you'll adjust your receive frequency DOWNward through the pass. I think others have basically explained why. Dave AD7DB

Doppler shift question
by Philip Jenkins 06 Jun '19

06 Jun '19

This came up at AMSAT Academy at Hamvention, and I still can't wrap my head around it (something simple I'm not getting, I'm sure). I know the xmit/receive frequencies aren't shifted, stay the same at the satellite. SO-50 has a 435 Mhz downlink; as the satellite approaches me from AOS I lower my receive frequency (and continue lowering it as the bird approaches LOS). So far so good. AO 91/92 have a 435 Mhz uplink,; as the satellite approaches me from AOS, I go up in my transmit frequency. Here is where I get lost: Why do I* lower* the frequency on 435 Mhz when receiving a satellite, but *raise* the 435 Mhz frequency when transmitting to a satelllite? So, my question boils down to - why should transmit doppler shift go in the opposite direction from receive on the same band? In both cases, the satellites are approaching me (from AOS). Basically, why the difference when I'm transmitting and when I'm receiving? 73 Philip N4HF

AMSAT NEWS SERVICE SPECIAL BULLETIN ANS-157 The AMSAT News Service bulletins are a free, weekly news and infor- mation service of AMSAT North America, The Radio Amateur Satellite Corporation. ANS publishes news related to Amateur Radio in Space including reports on the activities of a worldwide group of Amateur Radio operators who share an active interest in designing, building, launching and communicating through analog and digital Amateur Radio satellites. The news feed on http://www.amsat.org publishes news of Amateur Radio in Space as soon as our volunteers can post it. Please send any amateur satellite news or reports to: ans-editor at amsat.org. You can sign up for free e-mail delivery of the AMSAT News Service Bulletins via the ANS List; to join this list see: http://www.amsat.org/mailman/listinfo/ans In this edition: * AMSAT President Awarded Russian E.T. Krenkel Medal SB SAT @ AMSAT $ANS-157.01 ANS-157 AMSAT News Service Special Bulletin AMSAT News Service Bulletin 157.01 From AMSAT HQ KENSINGTON, MD. DATE June 6, 2019 To All RADIO AMATEURS BID: $ANS-157.01 AMSAT President Awarded Russian E.T. Krenkel Medal AMSAT President and ARRL Life Member Joe Spier, K6WAO, has been awarded the Russian E.T. Krenkel Medal, a prestigious award granted to individuals and organizations for outstanding global contributions to Amateur Radio. Joe Spier, K6WAO is a long time supporter of Amateur Radio in Space and international cooperation. K6WAO is the President of the Radio Amateur Satellite Corporation (AMSAT). He has also served AMSAT as Executive Vice President, and Vice President, Educational Relations. He is a long term supporter of Amateur Radio on the International Space Station (ARISS) and scientific, technical, engineering, and mathematics education. Spier is an AMSAT Life Member. He also is a Life Member of American Radio Relay League (ARRL) and the Society of Amateur Radio Astronomers (SARA). The award's namesake, Ernst Teodorovich Krenkel, was a radio amateur who, over the years, used the call signs RAEM, U3AA, and UA3AA. Born in Poland, Krenkel was an Arctic explorer who took part in the first Soviet "drifting station," North Pole-1. He was made a "Hero of the Soviet Union" in 1938 for his exploits. Krenkel's son, T.E. Krenkel, is among the four signatories to the award certificate. The younger Krenkel, a professor at the Moscow Technical College of Telecommunication and Informatics, said his father was an avid radio amateur who served as the first chairman of the Central Radio Club in the USSR. Krenkel's image appears on postage stamps from the USSR and Russia, and he authored a biography entitled My Callsign is RAEM. In the era when all radio amateurs received QSL cards via Box 88, Moscow, Krenkel was allowed to have his own postal address on his QSLs and was issued the non-standard RAEM call sign. Information about the Krenkel Medal can be found at: http://krenkelmedal.org/index.php?id=49 [ANS thanks the Russian National Academy of Researches and Discoveries for the above information] /EX In addition to regular membership, AMSAT offers membership in the President's Club. Members of the President's Club, as sustaining donors to AMSAT Project Funds, will be eligible to receive addi- tional benefits. Application forms are available from the AMSAT Office.

SSB is just 1/3rd of AM (one sideband, no carrier), and we still have doppler to deal with on the linear sats.... What do you mean by this? --Roy K3RLD > More train Doppler effect. > These are sound waves, but the RF FM principle is the same. > Not sure why they don't use AM in space, like in aviation...I.e.

SatPC32/IC-9700 Start Up Issue
by Frank Karnauskas 06 Jun '19

06 Jun '19

After watching Daniel, W5EKG's You Tube video, I had SatPC32 and the IC-9700 working beautifully on the first try. (Thanks, Daniel!) The radio frequency tracked the software real-time just like it should. However, after playing around for a few minutes (changing satellites, turning the main tuning knob, etc.) The radio suddenly stopped following the frequency changes from SatPC32. The frequency intermittently updates after 10-20 seconds accompanied by the frequency on the radio display flashing white from MAIN to SUB for a brief moment. Usually nothing happens until I choose another satellite then the frequency updates once then...crickets. Pertinent information: Windows 10 IC-9700 Firmware 1.05 Icom Driver Version 1.30 Baud Rate: 19200 (Tried dropping it to 9600) The AFC is turned off. Tried rebooting the software. Tried rebooting the computer, etc. Any clues? 73, Frank FRANK KARNAUSKAS, N1UW

Everett WA Everett High School STEM Demonstration
by johnv＠frontier.com 05 Jun '19

05 Jun '19

I will be at the Everett Sr. High School with 15 - 20 Physic students and their teacher to demonstrate the concept of Amateur Radio using a satellite - AO-91. It's near the end of the school year and the teacher will be doing hands-on project which include a balloon launch with a smart package that will tell GPS, temperature, direction using APRS. I will be setting up my tripod with a PA system for work as many of you as I can. Wednesday Jun 5 at 12:29 (PDT) 1929 UTC from Grid CN87. (I know, not the most rare grid). We will be on the front lawn of the school. I hope we can demonstrate how well we can exchange calls and grids in the shot time it's over us. Any suggestion, please email me offline Thank you John Van DalenN7AME
