SSB 70cm Pre AMp
by Peter Wilson 11 Apr '10

11 Apr '10

Hi Everyone, Just set up my station and started to receive all the main satellites, using a Gulf satellite antenna (2M + 70cm) + SSB 70cm Preamp and FT736R When I transmit on 2M, especially FM, it's as if the preamp is squelching - the receive signal reduces significantly. If I turn the preamp off I don't get the problem, I can continue to hear the received signal. Any ideas? Peter Wilson G8KEK AMSAT UK 6897

Re: AO-51 power up, PL test tomorrow

Hi Drew, On our clear pass south to north into ZS, at 16h07 utc, the bird was off and switched on with tone. Stayed on for 120 secs after PPT recycled. Goes off even though a tone station is busy. Works just fine ! Nice to have the higher power output from the bird. I presume this mode will save some power in swithing TX off ? 73 andre zs2bk

Remarks
by ps8rf Piraja 11 Apr '10

11 Apr '10

Hello Friends, I have two observations: The first - the team control of the AO-51 correctly employed the use of PL tone to activate the bird. Here in South America constantly listen to interference from phones and others strangers broadcasts through its downlink. I hope the use of PL tone is adopted and so permanent. The second observation is related to EME - our friend Roland, PY4ZBZ managed to received the signals from the Arecibo Radio Observatory on 22/03/2010 at 21:30 UTC in 432.045 MHz with only a small UHF antenna for 6 elements and a simple FT1000d transceiver. Roland with his equipment received signals in CW and SSB. Congratulations to our dear friend Roland, who with his feat, he broke the paradigm that is not possible with a simple antenna on hand to listen to a broadcast EME. Taking into consideration the power and the antenna used by KP4AO. The Antena: http://www.qsl.net/py4zbz/antenas/owa.htm#9 CW audio: http://www.qsl.net/py4zbz/satelite/KP4AO_EME_CW.wav SSB Audio: http://www.qsl.net/py4zbz/satelite/kp4ao_eme.wav Entire informations and graphics: http://www.qsl.net/py4zbz/satelite.htm#rl 73, Piraja, PS8RF The Amateur Radio is supportive and helpful in any circumstance _________________________________________________________________ O Internet Explorer 8 te dá dicas de como navegar mais seguro.

BeeSat at 4800 GMSK
by Nathaniel S. Parsons 11 Apr '10

11 Apr '10

Hi all, I didn't get a response the last time I asked, so I'll try again, slightly differently. What TNC or TNC-like equipment do I need to listen to BeeSat at 4800 bps? I have a TS-2000, yagi antenna, rotator, and KAM-XL, but the KAM-XL can only do GMSK at 9600 bps. Thanks in advance for your time, Nate KC2SVI

AO-51 power up, PL test tomorrow
by Andrew Glasbrenner 11 Apr '10

11 Apr '10

This evening I shut the 435.150 transmitter off and raised 435.300 to near 2 watts output. Tomorrow morning I plan to turn on the new PL routine. This improved routine will turn the downlink on with an unsquelched uplink when it hears a 67 hz tone. I plan on leaving a tail of several minutes, so the transmitter will stay on without hearing a tone for an interval of several minutes. What does this mean for the user? It would be helpful to program in a 67 hz PL tone again, but not absolutely required as long as someone else in the footprint does. It also means if you are the first person in the footprint (not very likely in North America, Europe, or Japan) you might not hear the satellite until after it hears 67hz for a few seconds. If all goes well, we'll continue this mode through the mode change Sunday night. Reports from when the downlink turns on or off would be appreciated. 73, Drew KO4MA AMSAT-NA VP Operations

The proposal is for a 1U CubeSat in Low Earth Orbit (LEO) with UHF downlinks and a VHF telecommand uplink. It is hoped to launch in 2012 although no launch opportunity has yet been confirmed. ESTCube-1 will carry a camera to acquire images of Estonia for out reach purposes and will deploy a 10 meter conductive Hoytether as a part of the development work of an electric solar wind sail.

April 11, 2010 To All RADIO AMATEURS BID: $ANS-101.06 The Arecibo Observatory Amateur Radio Club will be putting the 1000-foot radio telescope on the air for 432 MHz EME from April 16-18. It can be heard with a small hand-held yagi pointed at the moon The scheduled times of operation are: April 16: 1645 - 1930 UTC April 17: 1740 - 2020 UTC April 18: 1840 - 2125 UTC Callsign: KP4AO Tx Frequency: 432.045 MHz Rx Frequency: 432.050 to 432.060+ Tx power: 400 W Antenna gain: 60 dBi System noise temp: 120 K (cold sky) System noise temp: 330 K (when pointed at moon) KP4AO can be heard with a small hand-held yagi pointed at the moon and a good receiver. A 15 dBi antenna and 100 W will be enough to work us on CW. Operators at KP4AO will do their best to work as many stations as possible. Each session will start with a brief announcement and CQ in SSB. SSB QSOs may continue for 30 minutes to an hour, if the QSO rate remains high. The mode will be shifted to CW as soon as it is judged that higher QSO rates would result. We will listen for calls at frequencies 5-15 kHz higher than our own, and even higher if QRM warrants. Callers who s-p-r-e-a-d o-u-t are more likely to be copied. If you've already worked us in any mode, please do not call again -- give others a chance. If we call "CQ QRP", we will listen for stations running 100 W or less to a single yagi. Please do not answer such a CQ if you are running more power or have a larger antenna. On April 18, if we reach a condition where most calling stations have been worked, and we judge that operating in the digital mode JT65B would produce a higher QSO rate, we will switch to JT65B. Note that any of these planned operating strategies may be changed as circumstances dictate. We are extremely fortunate to have been granted access to the world's largest radio telescope for this amateur radio good-will event. We look forward to working as many stations as possible in the alloted time!

April 11, 2010 To All RADIO AMATEURS BID: $ANS-101.07 1. Astronaut Soichi Noguchi Chats with Texas Students via ARISS Contact On Monday, March 29, Walnut Creek Elementary School students in Azle, Texas took part in an Amateur Radio on the International Space Station (ARISS) contact with JAXA astronaut Soichi Noguchi, KD5TVP. All 23 questions were answered with time for a two way "Goodbye." ARISS was integrated into the science curriculum as students researched space objects and gave presentations to their class. The youth also attended satellite communications demonstrations given by retired Lockheed employees and members of local radio clubs. On the day of the contact, a proclamation was read by an Azle City representative declaring it to be Space Day in Azle. Four television stations and one local newspaper covered the event and the audio was available on EchoLink. 2. HAMEX 2010 ARISS Exhibit HAMEX 2010, the largest RadioFest in Canada, was held on Saturday, March 27 in Toronto. AMSAT (Radio Amateur Satellite Corporation) and ARISS (Amateur Radio on the International Space Station) members attended the event and manned an exhibition booth which displayed two mini satellite communications stations as well as information boards with pictures of astronauts involved in the ARISS program. A large AMSAT banner was posted, along with two 7 foot posters on loan from the Canada Space Agency (CSA). CSA also provided handouts, stickers and various magnetic logos, which along with pamphlets describing AMSAT and the ARISS program, were distributed to the many visitors the exhibit attracted. The event was a success in generating interest in the ARISS program and the team was invited back next year. [ANS thanks Carol, KB3LKI, 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 additional benefits.
