Another first: rotor problems
by Hans BX2ABT 24 Jun '19

24 Jun '19

There is a first for everything. So today for the first time in my 10 years as an amateur radio operator I experienced that my KR-400 rotator (partially) stopped working. It has not been in use for 10 years, only the last 8 months and the motor was cleaned and greased before the install. Before I start dismantling everything I would like to see if any of you have any good advice. The problem --- it will turn right, not left. What I measured --- between terminals 5 and 6 (right turn) I measured 31 Volts, which is normal. Between 4 and 6 (left turn) only 21 Volts. Rotor not connected to the controlling box when measuring. My thoughts --- must be in the controlling box. However, there is simply nothing there in the circuit that I think could act up. From the transformer one terminal carrying 29 Volts goes to two switches. The other terminal is neutral. There is the light bulb between the two terminals and a 70 uF/50V capacitor between the two switches. I could be entirely wrong, so spill any info and/or tips that you can give me, here. Cheers, Hans BX2ABT

That's what I was using.?? Like I said, I was probably just out-gunned by more powerful stations. 73, Mac / AE5PH On 6/23/19 11:01 PM, Stephen E.

G5400B rotor problem
by Richard Lawn 23 Jun '19

23 Jun '19

I have an old 5400B that I use at a summer location. I use another old fox delta serial control interface that emulate GS-232. It has developed a strange problem with the AZ rotor that seems to occur when it reaches the extreme S (past E) where it tends to freeze. The only way to unfreeze it and gain control again is to shut the control box off for a short time and then it will run fine manually or under control by SATPC32. I’m guessing there may be some thermal device inside the rotor itself that is exceeding a limit and needs to cool down. I’d love to hear some suggestions on what the problem might be. Tnx Rick, W2JAZ -- Sent from Gmail Mobile

Re: [amsat-bb] Operating with the THD-72 handheld
by gw1fky＠aol.com 23 Jun '19

23 Jun '19

Hi,Regarding the problems of operating with the THD-72 ( or other portable ) and avoiding the tangle of wires etc.Patrick WD9EWK/VA7EWK mentioned that he has a "Bluetooth" speaker with a jack socket. It is much easier to obtain a a " Bluetooth" audio transmitter and thus avoid the need for any wires. These transmitters are reasonable cheap and available from a number of well known sources.Simply plug the Blue tooth Tx into THD-72 audio jack and pair with the Bluetooth speaker - You canadjust the THD-72 volume control to suit your conditions.The size of these Bluetooth transmitters is sometimes smaller than an SDR dongle, some even have a wired jack plug fitted. I have used this method not only for portable operation, but also for demonstrations, It made it much easier for those listening and myself of course."WIRELESS" Hi Hi. Ken EatonGW1FKY PS.The method can be used with many other radios etc and I have used it to set up my LNB/dish to monitor QO-100 down link/ beacons and operators. ( An AOR receiver on 739 Mhz SSB )

[ANS thanks Clayton L. Coleman, W5PFG, AMSAT Secretary, for the above information] --------------------------------------------------------------------- Help Celebrate AMSAT’s 50th Anniversary – Take W3ZM on the Road! Leading up to the 2019 AMSAT 50th Anniversary Space Symposium and General Meeting, to be held in Arlington, VA, October 18 – 20, 2019, AMSAT’s call sign, W3ZM, will operate from all 50 States, the District of Columbia, and Puerto Rico. Not only is this your chance to get Worked All States-Satellites under the W3ZM call sign, but, also, your chance to be a part of this historic effort. Note: When operating outside of the “3” call area, operators will append the W3ZM call sign with “/(call area).” As an example, someone operating from Texas will use W3ZM/5; from Hawaii, W3ZM/KH6; from Alaska, W3ZM/KL7; and from Puerto Rico, W3ZM/WP4. To make this happen – We need your help! Please volunteer to get on the air and activate your State, using AMSAT’s W3ZM call sign, as well as to cover those States without an active AMSAT Member. Activations of other United States Territories (i.e. Guam, American Samoa, the U. S. Virgin Islands, and the Commonwealth of the Northern Mariana Islands) are also welcome. To volunteer and operate using AMSAT’s W3ZM call sign, you must: Be a current member of AMSAT Obtain permission by emailing AMSAT VP of User Services, specifying the requested date(s) and location(s) Submit an ADIF log of contacts made for upload to LoTW by AMSAT, as instructed in your notice of approval to use the W3ZM call sign [ANS thanks Robert Bankston, KE4AL, AMSAT VP of User Services for the above information] --------------------------------------------------------------------- +=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+ 2019 marks AMSAT’s 50th Anniversary of Keeping Amateur Radio in Space.

This cubesat will be propelled solely by sunlight, to Earth orbit. LightSail 2 is scheduled to launch aboard a SpaceX Falcon Heavy on June 24, 2019, and we will attempt the first, controlled solar sail flight in Earth orbit. LightSail 2 will ride to space aboard the Department of Defense Space Test Program-2 (STP-2) mission which will send 24 spacecraft to 3 different orbits. LightSail 2 itself will be enclosed within Prox-1, a Georgia Tech-designed spacecraft originally built to demon- strate close-encounter operations with other spacecraft. Prox-1 will deploy LightSail 2 seven days after launch. After a few days of health and status checks, LightSail 2's four dual-sided solar panels will swing open. Roughly a day later, four metallic booms will unfurl four triangular Mylar sails from storage. The sails, which have a combined area of 32 square meters [344 square feet], will turn towards the sun for half of each orbit, giving the spacecraft a tiny push no stronger than the weight of a paperclip. For about a month after sail deployment, this continual thrust should raise LightSail 2's orbit by a measurable amount. LightSail 2 will fly in a 24-degree inclination, 720 km, circular orbit. At latitudes of 42 degrees north it will reach a maximum elevation of 10 degrees above the horizon. Lightsail-2 has been issued an experimental radio license WM9XPA and transmit on 437.025 MHz. A morse beacon will transmit the callsign every 45 seconds. A packet beacon will transmit AX.25, FSK 9K6 bps data.

During the June 17 event students in the program were provided with two opportunities to learn about space communications from widely different perspectives. The first session was led by Radio Amateur Satellite Corporation (AMSAT) president Joe Spier – the second by Dave Israel, the Exploration and Space Communications (ESC) projects division’s lead architect. With Spier, SCaN interns got the chance to learn about AMSAT, a volunteer organization that designs, builds, launches and commands amateur radio payloads on satellites. SCaN intern and “ham” Caitlyn Singam was required to pass a rigorous FCC exam to be given her unique callsign, AC3AG, at the highest level of certification, ‘Amateur Extra-class’. Given her history with amateur radio the talk was particularly inspiring. “I actually ended up talking to Mr. Spier afterwards about getting involved in AMSAT,” Singam said. “It was really exciting.” Singham enjoyed learning about Spier’s unconventional route to AMSAT, which she related to in her own academic career. “I’ve had an interesting route myself, with biological sciences and a master’s in systems [engineering] in the fall,” she said. Spier’s route took him from a background in geology to becoming a leader in the small satellite community. He had early dreams of becoming the first to climb Olympus Mons, the highest peak on Mars. Today, he refers to the interns as the ‘Mars generation,’ hoping that an intern today might summit that peak in the near future. He shared his personal strategy on making big NASA dreams come true: “I always clarified it by saying, ‘If I can’t be that person, I want to help someone else be that person.’” In the afternoon, SCaN interns met with ESC’s lead communications architect for an overview of division projects. Israel’s work at NASA spans 30 years. Interns heard about topics ranging from the development of Tracking and Data Relay Satellites (TDRS) in the late 1980s to the Space Mobile Network, a concept for an interplanetary internet that Israel envisions coming to fruition in the near future. Israel, like Spier, offered the SCaN interns in attendance some advice: “Never keep any good ideas to yourself, and don’t worry about asking questions from a different perspective,” Israel said. “A question from a different perspective gets people to think about it in a different sort of way.” "Never keep any good ideas to yourself, and don't worry about asking questions from a different perspective." Dave Israel, ESC Communications Architect To Grace McFassel, a SCaN intern who attended the talk, Israel’s story was not only interesting, but inspiring. “He [has] this specific skillset that he dearly loves, and he’s used that to carry himself through by finding niches where he can be useful,” McFassel said. “It’s a good lesson to carry forward.” To learn more about SIP or SCaN, visit NASA.gov/SCaN.

I have released version 1.01a of the G0KLA Satellite tracker. I had hoped to get it out further in advance of field day, but work pressures got in the way. Anyway for those of you in the US, here it is the day before :) This version has a few tweaks, most requested by users. * Key display settings can be changed on the main window from a set of icons bottom left. e.g. showing spacecraft in eclipse vs sun. * You can display horizontal lines for 30 and 60 degrees. * You can display horizontal lines for all labels on the vertical axis if you want * Time labels have a slightly more sensible gap between them, e.g. 15 mins, vs a random amount that fit in the window like 13 mins * Past mins can now be as short as 10 mins, though you can also specify a long period if you want The downloads are in the usual place here: http://www.g0kla.com/klatrack/KlaTrack_1.01a_windows.zip http://www.g0kla.com/klatrack/KlaTrack_1.01a_linux.tar.gz http://www.g0kla.com/klatrack/KlaTrack_1.01a_mac.tar.gz 73 Chris g0kla / ac2cz -- Chris E.

Ted, Let this 'no code General' help you with satellite info. https://www.amsat.org/fm-satellite-frequency-summary/ <https://www.google.com/url?q=https://www.amsat.org/fm-satellite-frequency-s…> https://www.amsat.org/linear-satellite-frequency-summary/ <https://www.google.com/url?q=https://www.amsat.org/linear-satellite-frequen…> https://www.amsat.org/two-way-satellites/ <https://www.google.com/url?q=https://www.amsat.org/two-way-satellites/&sa=D…> You can love the ARRL all you want, it's OK. I personally feel that no info is better than wrong info. And in full disclaimer, I haven't been an AMSAT member or ARRL member for some time because I didn't agree with things, but yet I contribute and try to help those that have operating questions. At least I'm not on an ARRL BB complaining about them and not a member. Gotta go now and try keeping that horse stuff in the stalls.

Doppler adjustment proper procedure question

On the official ARRL VHF/UHF info sheet (http://www.arrl.org/files/file/Field-Day/2019/2019%20Above%2030%20MHz%20-%2…) they suggest that for satellite QSOs operators should only adjust their receive frequency regardless of whether it is VHF or UHF. I thought standard procedure was to adjust the higher frequency whether it is transmit or receive. Steve AI9IN
