Re: China has anti-sat missile

Hi AMSATs, Unfortunatly the Chinese blow up the satellite into many peaces. It would have been a better action when they push back the satellite towards earth, but at some 850km satellite altitude its not that easy I guess. Maybe next time they can show a better use for their rockets by giving a free-ride to a hamsat ;o) About the space debris, I red some article about 2 weeks ago. It was from a NASA investigation showing how many debris per country is contributed (mainly rocket parts). It was an older pdf document, and very interresting. Unfortunatly I can not find it anymore, but the number behind "USA" and "USSR" were one of the largest. In my search for that document I find some other interresting webpage showing debris in orbit. Have a look at: http://orbitaldebris.jsc.nasa.gov/photogallery/beehives.html#geo William, PE1RAH --- __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

PCSAT-1 critical
by Robert Bruninga 19 Jan '07

19 Jan '07

PCSAT-1 just crashed due to overload of users at 2110z on the 18th. Fortunately I heard it during a pass, and was able to quickly restore the low power settings before eclipse. But if PCSAT resets without a control operator in view, we will lose PCSAT-1 for the next two months until the March full sun period. As of this moment, I turned off all alias digipeating to cut down on the load to see if she will make it through eclipse. We ask all users to adhere to the following situation: 1) Cease all operations at night 2) Limit your packets during the day to minimum to make contact 3) Never digipeat VIA W3ADO-1 The only exception to the rule #1 is for new users who have not had the chance to try PCSAT-1 from their mobile D7 or D700 radio, to set an overnight beacon at a 5 minute rate to see if they capture any packets overnight. Since I turned off all aliases, such users participating in that experiment will have to set their PATH to VIA PCSAT-1. Bottom line. PCSAT-1 has had a great run since 1 January with over 100 users per day showing up on the web page http://pcsat.aprs.org . And we can continue this operation as eclipses get longer and longer as long as we do not overload it. The load she has been seeing the last week is not sustainable. We welcome activity, but need to reduce the load. Please cut back on y our transmission rates. If you see the callsign W3ADO-1 it means a reset. If you see the callsign PCSAT-11 on 145.825, it means a reset If you see the callsign W3ADO-1 on 144.39 over the USA, it means a reset. If any sysop sees these conditions, please logon and restore PCSAT-1 to low-powerbudget opertions. Thanks Bob, Wb4APR

Re: part number need for G550 connector
by Wayne Estes 18 Jan '07

18 Jan '07

Nanaboshi NJC-207-PF is the connector on the cable. Nanaboshi NJC-207-RM is the connector on the motor. You can purchase this connector from various industrial equipment suppliers for much cheaper than what Yaesu sells it for. A few years ago I did a bulk order for more than 100 of these connectors. The connectors were about $8 each, but they did not come with the rubber boot. At the time Yaesu was asking $48 each, with the rubber boot. Wayne Estes W9AE Oakland, ORegon, USA, CN83ik p.s. Last night I made my first AO-27 contacts in several years.

Symposium Information - BOFS
by Emily Clarke 18 Jan '07

18 Jan '07

For those of you who are attending the Symposium there is a new feature we are going to try this year called BOFS - Birds Of a Feather Sessions. BOFS are generally free-form meetings that are held after-hours and may be called by anyone wishing to start a discussion group. They have been common at software conferences I've gone to in the past and were very popular. An example of a BOF for the AMSAT Symposium might be to start a discussion about groundstation antennas. I have set aside two rooms (one holding 12 people, another holding 20) beginning at 6pm on Friday evening. The procedure is pretty straightforward: 1) Develop a title for your BOF - say "Homebrew Groundstation Antennas" 2) Estimate the amount of time you would like for your BOF - BOFS usually last 30 minutes or an hour 3) Go to the registration desk and tell someone there that you want to start a BOF. They will give you a flip-chart sized (2 foot by 3 foot) Post-It note and assign you a room and time. 4) Write your title, time and room on the large Post-It note and tack it on the wall outside of the Symposium meeting room. And that's it! 73, Emily --------------------------------- N1DID formerly W0EEC - CM87tm Support Project OSCAR - http://www.projectoscar.net

Oh Joy!
by Matt 18 Jan '07

We now have have ANOTHER bunch of beeping boxes. And I am glad to say AMSAT will give them a bunch of nice numbers to say that they are "ham satellites". It's a good thing I kept that 2M FM rig, I can drive around and say to my kids " that's a satellite" as we drive to and from school. I was looking at my log from my novice days. I want from hearing my 1st bird (RS40) on FM, to SSB bird (RS-15) to HEO (AO-10) to mode S (AO-13) in 2 weeks. Maybe it just me aye? http://www.amsat.org/amsat/archive/amsat-bb/200109/msg00037.html

Sat on 437.380?
by Robert Bruninga 18 Jan '07

18 Jan '07

My receiver set for FCAL satellite on 437.380, also is hearing a dead carrier with doppler a few times a day when FCAL is no where around. This sure sounds like a satellite to me. But then it could be alocal birdie that sweeps slowly through my passband every day as temperatures oscillate. I just heard it today at 1450z over Washington DC apparently headed south? Anyway, I wonder if anyone else has heard it. I hear it every day. At first I just discounted it as terrestrial intermod, but this open squelch was so strong today, I went over and swung the beam and it definitely had a bearing and that bearing was definitely different than the only other time I looked at it a week ago... Doppler and signal going down... And then it was gone.. I'll try to remember to pay attention again in 90 minutes.. Bob, WB4APR

CO-56 Call Sign has changed
by Omagari Kuniyuki 18 Jan '07

18 Jan '07

Dear Amsat members, For various reasons, the call sign of our satellite, C0-56 (also known as Cute-1.7 + APD) had to be changed from JQ1YCC (old call sign) to JQ1YPC (new call sign). We are very sorry for the inconvenience and confusion this might engender, and wish you could update your database as well as the various documents and pages referring to our satellite's call sign. In advance, we thank you very much for your trouble and will do our best to provide improved services to the amateur radio community with Cute-1.7+APD II. http://lss.mes.titech.ac.jp/ssp/cute1.7/index_e.html Best regards, Omagari Kuniyuki for The Tokyo Institute of Technology Cute1.7+APD team.
