[amsat-bb] Yaesu G-5400B and G-5500 controller
Hallo! I am owner of both the Yaesu G-5400B and the G-5500 azimuth/elevation controller. Could someone tell me: What kind of rotators (Azimuth and Elevation) came with the G-5400B? What kind of rotators (Azimuth and Elevation) came with the G-5500? None of the rotators are marked with type or part number. 73 de Sven LA6KJ ___ Sent via AMSAT-BB@amsat.org.

[amsat-bb] ANS-130 AMSAT News Service Special Bulletin ARISSat-1 Update
SB SAT @ AMSAT $ANS-130.01 AMSAT News Service Special Bulletin - ARISSat-1 Update AMSAT News Service Bulletin 130.01 >From AMSAT HQ SILVER SPRING, MD. May 10, 2011 To All RADIO AMATEURS BID: $ANS-130.01 The ARISSat-1 satellite was intended to be activated in April as part of the 50th anniversary of Yuri Gagarin's famous flight. However, no ground stations reported hearing the satellite. To follow up, the ARISSat-1 team had a teleconference with represent- atives of RSC-Energia (Russia) and NASA to request a clarification of the events and discuss what happened. According to RSC-Energia, the battery in ARISSat-1 was only charged once on the ground and was then used for a variety of tests and dur- ing the February activation event. It was not recharged prior to the April Yuri Gagarin activity since it can only be charged a limited number of times on the ISS. The cosmonauts reported that they activated the satellite and con- firmed that they heard the signal on the ham radio equipment on board the ISS. Since the battery was nearly depleted of its original charge, they switched the satellite off after six hours of operation in order to prevent over-discharging the battery. The battery was then removed from the satellite and stored separately as per their normal battery handling procedures. For more information on this battery, please see the JAN/FEB 2011 AMSAT Journal. RSC-Energia reported that their plan is to recharge the battery about three weeks prior to the EVA deployment. This will give the cosmonauts time to reinstall the battery and test the satellite to make sure it is working properly. The EVA deployment is planned for late July of this year.

[amsat-bb] New Link on AMSAT.org Web - AMSAT-OSCAR Slide Show from Space Day 2011
Hello Everyone, AMSAT and ARISS participated in Space Day at the National Air and Space Museum on the Mall in Washington, DC on Saturday, May 7. We featured display tables and ARISS had a contact with the ISS. More coverage on this event will be in upcoming ANS bulletins and in the AMSAT Journal. Perry, W3PK says at Space Day, AMSAT showed a new version of the AMSAT-OSCAR slide show. Perry took Dick Daniels, W4PUJ, slides, added captions and converted them to PowerPoint. We have added the slide show file as a PDF to the http://www.amsat.org front page. The link is directly below the paypal donation widget. This is a fascinating document of AMSAT's proud history, tradition, and heritage of amateur radio in space. -- 73 de JoAnne K9JKM k9...@amsat.org Editor, AMSAT News Service ___ Sent via AMSAT-BB@amsat.org.

[amsat-bb] KB5WIA California Lost Coast (CM79/CM89/CN70/CN80) August 6-9 2011
Hi Everyone, Just FYI, plans are coming together for a satellite mini grid-expedition in early August this year. The idea is to camp out near Shelter Cove on the remote northern California Lost Coast area. As much as possible, I'll hike with the portable satellite gear (Twin FT817ND's, Elk antenna, solar panels and battery) and work from the grid intersection of CM79, CM89, CN70, and CN80. This is the same location that was activated on 6m last year for the completion of the FFMA award -- CM79 is a pretty rare grid, and the adjacent ones aren't terribly common in the sat community either. As usual, I'll try for as many linear and FM passes as I can manage. Operation (and the trip itself!) is still dependant on weather and other factors, but I just wanted to give the group a heads up on this one. 73 de Dave KB5WIA ___ Sent via AMSAT-BB@amsat.org.

[amsat-bb] Re: searching advice on low hpass filter for 146 MHz
Hi, KA1RRW I was looking at the passband filter DCI 145-2H with center frequency of 145 MHz but it has a flat responce 4 MHz large from 143 to 147 MHz (see the skirts diagram) so that it canno't attenuate the very strong POCSAG signal that HB9BNK has at 147.300 MHz In addition I have not seen any notch added in all models for 2 meters band. Do you know if DCI can add a notch to a selected frequency upon customer request ? For example 145.900 MHz center pass-band frequency and a notch at 147.300 MHz ? It would be a very good soluction for Werner HB9BNK 73" de i8CVS Domenico - Original Message - From: "MM" To: "HB9BNK''Werner Kullmann" ; ; "Dee" Sent: Monday, May 09, 2011 8:12 PM Subject: [amsat-bb] Re: searching advice on low hpass filter for 146 MHz http://www.dci.ca/?Section=Products&SubSection=Amateur You can buy a custom low pass filter for 2-meters from DCI. Marex had DCI custom build a 2-meter filter for simular usage on Mir. The filter passed 144.000 - 146.000, and had a notch added for 143.xxx. The filter worked great.

There are six commands that have to be given in sequence to make this work, and for the time being, one at the end of a pass. It's important to shut things down to keep from damaging the batteries even further in eclipse. There may be a small chance for a brief recovery in the fall of this year, and we don't want to endanger that by further harm to the batteries. In the meantime, listen to 435.150 during the afternoon passes over the Eastern US, especially on weekends and holidays. If you hear voices, the repeater should be available for use with a 145.880 uplink. If you don't hear anything, don't transmit. This is IMPORTANT: There are no promises or predictions of when we will get the chance to run the repeater. It is on an 'as available' basis. Please don't e-mail asking when it will be on, unless it's for a very, very special event. If I know in advance, I'll drop a note to here or to the AMSAT twitter account. That being said, this afternoon is looking good. 73, Drew KO4MA AMSAT-NA VP Operations ___ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?

[amsat-bb] Re: Iss repeater or crossband.
Kev, I believe the decision is made by the ISS crew. This website tracks the current status and may give clues to upcoming events: http://www.issfanclub.com/ I believe that most of the time the station works in digipeater mode. I have been experimenting with using this over the past couple of weeks and its really kinda neat. It only requires a single-band radio, a fixed antenna, and a TNC. http://home.comcast.net/~k9jkm/ARISS_Packet_How_To/ has great instructions on getting started.
