AO-92 in L/v Mode Over Europe
by Rocco Labella 21 Jan '18

21 Jan '18

Worked Fer IW1DTU yesterday at 09:08 UTC via AO-92 in L/V mode over Europe. Good signal using transverter +20W PA directly under a 23 element yagi orizzontal polarization. Unfortunately the transverter IF is on the same satellite downlink band so I can't hear myself but I am working out this issue. Here a short QSO video https://youtu.be/ifjEKS-HhBc TNX to AO-92 Team 73, Rocco IK8XLD

Is This a Connector? If so, what kind?
by anderson58625 21 Jan '18

21 Jan '18

Hello! Not being especially familiar with microwave equipment, I came across a type of connection which is currently a mystery to me. I know it is a connection, but I'm not sure if it is a connector. In seeing pictures of some microwave PA's, sometimes a fine pin or pins are on the chassis for voltage connection. But, is it a connector? If so, what kind? (with that I can Google my way to more information) I'm guessing the connection is special to ensure insulation and the integrity of chassis shielding(?), but I can't seem to find the mating female connector (if that pin is indeed a connector and not just a connection). I'm guessing the BB won't allow images inside a message, so there are some examples at https://forums.qrz.com/index.php?threads/150-w-ssb-23cm-1-2ghz-amplifier-plu s-extras.596138/ (scroll down over half way). Not being even close to needing an amp-I just got my Arrow ant. but haven't even make a contact yet <grin>-I still must have interest or I wouldn't be daydreaming by looking at antennas, LNA's, transverters, and PA's online. Thank you! Mark W9AT

ANS-021 AMSAT News Service Weekly Bulletins
by E.Mike McCardel 21 Jan '18

21 Jan '18

AMSAT NEWS SERVICE ANS-021 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. In this edition: * Dr. Junior Torres de Castro, PY2BJO SK * AMSAT Membership Deal and Getting Started * Upcoming club satellite presentations (and hopefully demos...) * Zhou Enlai Student Satellite to Launch * AO-92 camera results * N8RO Logs 488th US Grid - Earns Grid Master Award #8 * Updates to AMSAT-NA TLE Distribution for 1-16-2018 * Fox-1 MPPT Developers Interviewed on HamRadio360 Podcast * ARISS News * Satellite Shorts From All Over SB SAT @ AMSAT $ANS-021.01 ANS-021 AMSAT News Service Weekly Bulletins AMSAT News Service Bulletin 021.01 >From AMSAT HQ KENSINGTON, MD. January 21, 2017 To All RADIO AMATEURS BID: $ANS-021.01 Dr. Junior Torres de Castro, PY2BJO SK It is with great sadness that the Directors and Officers of AMSAT- North America announce the passing of Dr. Junior Torres de Castro, PY2BJO. According to his son, Allan Kardec, Junior passed away on January 17, 2018 in Sao Paulo, Brazil. A very active radio amateur, Junior was a great collaborator of LABRE (The League of Brazilian Amateur Radio Transmitters) serving for a time as its President. He was also a founder of BRAMSAT, the Brazilian AMSAT group as well as an active member of the AMSAT-NA Board of Directors during the early 1990s. But, perhaps what Junior will be best remembered for among the rest of the world's amateurs was his work with AMSAT-NA in helping to build (and financially underwrite) Brazil's very first amateur radio satellite. Called "DOVE short for "Digital Orbiting Voice Encoder", the satellite was successfully launched on January 22, 1990 on an Ariane 4 rocket from the European Space Agency's Kourou Space Center in French Guiana. Besides the main payload, that launch also included three other AMSAT MicroSats along with two larger UOSats. Surrey Satellite Technology in England built the two larger satellites. Junior's vision for his DOVE satellite was to provide a strong 2m, audio FM downlink signal ("This is DOVE in Space") that could be easily received by educational institutions around the world. Downlink telemetry was via 1200 Baud AFSK, AX.25 packet radio, a data format that was easily decoded with receivers and TNCs that were very popular among radio amateurs at the time. When told of Junior's passing, Jan King, W3GEY, a founding AMSAT Director and AMSAT's Vice President of Engineering during the MicroSat project said that, "I'm very sorry to hear about Junior. He certainly made the 4 MicroSat mission happen. He was a very important part of AMSAT and a fond memory for me." Likewise, Former AMSAT-NA BOD member Bob McGwier, N4HY, noted that, "This is a sad day. Junior was a great guy, full of life, and he loved AMSAT. It was a pleasure for me to help build his MicroSat for him. When I became an AMSAT employee for getting these spacecraft done, Junior paid the bills." Another MicroSat Project team member, Jim White, WD0E, noted that, "This is indeed sad news. It was a pleasure to work with him on DOVE. He was a very warm and generous person and not only conceived of and funded DOVE, but also a receiver for the 60-foot radio dish that the Table Mountain the Deep Space Exploration Society was refurbishing. He was always tinkering and building things at his house near Sao Paulo. He even dreamed of building a round swimming pool that, when drained, would double as a radio astronomy dish! During the time his DOVE satellite was sending "This is DOVE in space" audio from orbit we received nearly 200 SWL cards from around the world, all of which we shared with him. Needless to say, he was absolutely delighted." At ANS deadline, funeral arrangements for Junior were still pending. But word was received that his funeral and interment was to be in at the Gethsemane Cemetery in Sao Paulo, Brazil.

Right now, we are offering a free PDF copy of our Getting Started with Amateur Satellites with every new on-line membership. This is -the- primer for getting on the sats, and is updated every year. See https://www.amsat.org/product-category/amsat-membership/ AMSAT also sells both the popular Arrow Antenna satellite models and the M2 LEOpack antennas. Sales also benefit AMSAT projects. https://www.amsat.org/product-category/hardware/ [ANS thanks AMSAT Office for the above information] --------------------------------------------------------------------- Upcoming club satellite presentations (and hopefully demos...) Philip N4HF announces a couple of presentations he'll be doing. 1) Blue Ridge ARC (Henderson County NC), Tuesday March 6, 7pm. http://radioclub.org/ (this club has also started streaming club meetings via TeamViewer; the demo, if it happens, will be outside though) 2) Haywood County ARC (NC), Thursday April 12, 7 pm. http://kw4p.org/ (Meeting place is incorrect on the website, but hopefully that will be updated in the next few days) Philip states he will be at one hamfest under the AMSAT banner, and possibly two, in the next couple of months. He will be announcing those when the info is finalized. [ANS thanks Philip N4HF for the above information] --------------------------------------------------------------------- Zhou Enlai Student Satellite to Launch The 2U CubeSat Zhou Enlai, developed with primary and middle school students, is expected to launch on Friday, January 19, 2018 The satellite is named after the first Premier of the PRC. Zhou Enlai held office from October 1949 until January 1976. A report on Xinhua Net says: The satellite was sent from its production base in Huai'an Youth Comprehensive Development Base in east China's Jiangsu Province to Jiuquan Satellite Launch Center in northwest China's Gansu Province Monday, where a CZ-11 solid fuel rocket is scheduled to put it into orbit Friday. Twenty teenagers who participated in the development project accompanied the transport group to the launch center and will witness the lift-off. Zhang Xiang, chief designer of the satellite, said that the nano- satellite, weighing 2 kilograms, is set to run in sun-synchronous orbit. Equipped with a HD optical camera, it can capture space photos with the highest resolution among those shot by other Chinese satellites for scientific education purpose. Zhang said that the students had taken their spare time to join the development and groundbased simulation performance of the satellite, and had learnt to assemble and practice voice data transfer and telecommunication applications. "A scientific satellite like this is like a teacher in space, carrying cameras or spectroscopes to study the upper atmosphere or to shoot space pictures of the stars. Students can grasp the mystery of the universe through the messages transmitted by the teacher," said Zhang, a professor with Nanjing University of Science and Engineering. Read the full story at http://www.xinhuanet.com/english/2018-01/17/c_136902466.htm The IARU satellite pages list a 2U CubeSat called HA-1 with FM transponder and SSTV developed by the Teenagers Amateur Radio Center of Activity in Huai'an. Zhou Enlai may well be the new name for this satellite. http://www.amsatuk.me.uk/iaru/finished_detail.php?serialnum=589 [ANS thanks Southgate ARN for the above information] --------------------------------------------------------------------- AO-92 camera results For those that have not been following AMSAT on Twitter or Facebook, we have done a few camera runs with AO-92 with very good results.

Re: [amsat-bb] Mast mounted low noise amps
by Gregory Beat 21 Jan '18

21 Jan '18

Bill - The Icom AG-series of mast mounted pre-amplifiers for weak-signal and satellite work are now legacy (I believe Icom has discontinued recently). A lower noise figure of the active device (FET, MMIC) is important for satellite work (sky), than weak-signal work (noisy terrain/earth). High noise-levels with the AG-series are often attributed to a Failed FET or an improper FET replacement by an earlier owner. Newer FETs have ESD / static protection, while older designs — DID NOT ! Nearby lightning strikes can damaged the FET on the AG-series pre-amps. Central States VHF Society annually performed Noise Figure tests on a variety of devices. This may be useful, as you examine modern devices or recent surplus. https://csvhfs.org/index.php/vhf-101/24-csvhfs-history/noise-figure-results The Icom mast-mounted pre-amplifiers (AG-25, AG-35) used the dual-gate Toshiba 3SK121 Dual Gare FET (discontinued). Schematics and manuals for the Icom AG-series are available via the Internet. http://www.radiomanual.info/schemi/ACC_preampl/Icom_AG-35_user_IW2HEU.pdf MODS.DK has the parts list and hand-drawn schematic for AG-35 (1999), the othe file AG-25 etc. Instructions has schematic for AG-25 (last page).
