CP4 is alive again
by Bryan Klofas 20 Jun '08

20 Jun '08

Hey Everybody-- We heard CP4 this morning, and decoded two beacons. It's beaconing every 5 minutes (yeah, too long period) on 437.325 MHz. Since it's been brain dead for the past year, we would like to gather as many beacons as we can to determine satellite health. We'll increase the beacon rate to once per minute probably tomorrow. Just send any data back to me. Thanks for all your help! Here's the data we got this morning: Found port: COM6 ---> BEGIN ACK <--- Source: 9C 6C 86 A0 40 40 E0 Dest: 9C 6C 86 A0 40 40 61 Response: COMM B ---> END ACK <--- ---> BEGIN SENSOR SNAP <--- Type: 01 (Sensor Snapshot) SeqNum: 36377 RTC: 10:9:14 (HH:MM:SS) -- Side Panel Data -- JPx: SPV/SPI/PPTI/MAGI/MAGA/MAGB/INTT/EXTT/3VSP JP5: 4.5 V 1.8 mA 11.0 mA 3.7 mA 5E 95 4.3 C 1.0 C 3.0 V JP6: 4.5 V 12.9 mA 18.4 mA 3.7 mA 7C B0 -5.2 C -4.3 C 3.0 V JP7: 4.2 V 1.8 mA 0.0 mA 14.7 mA 99 2D 2.1 C -0.3 C 3.0 V JP8: 4.5 V 207.7 mA 176.5 mA 5.5 mA 8E 60 39.7 C 42.6 C 3.1 V JP9: 4.3 V 0.0 mA 0.0 mA 3.7 mA 65 86 12.9 C 12.4 C 3.0 V -- CDH Data -- CDHDAQ: RFAI = 0.0 mA CDHDAQ: RFBI = 46.0 mA CDHDAQ: 3CDH = 2.9 V CDHDAQ: RFAT = 4.3 C CDHDAQ: 3VCA = 2.9 V CDHDAQ: 3VCB = 2.9 V CDHDAQ: VSUM = 4.2 V -- Power Data -- POWDAQ: CDHI = 29.4 mA POWDAQ: SPAI = 27.6 mA POWDAQ: SPBI = 20.2 mA POWDAQ: CAI = 18.4 mA POWDAQ: CBI = 7.4 mA POWDAQ: PAYI = 9.2 mA POWDAQ: CDHT = -1.6 C POWDAQ: CAPT = -5.7 C POWDAQ: CBPT = -4.6 C POWDAQ: 3SPA = 2.9 V POWDAQ: 3SPB = 2.9 V -- Battery A Data -- BATA: PROT = 11000011 OV: Cell Overvoltage Fault UV: Cell Undervoltage Fault /COC: No Charge Overcurrent Fault /DOC: No Discharge Overcurrent Fault /CC: Charge Protection Inactive /DC: Discharge Protection Inactive CE: Charging Enabled DE: Discharging Enabled Status = 11000111, 4.3 V, 0.0 C, 80.0 mA AccCurr = -5791.0 mAh -- Battery B -- BATB: PROT = 11001011 OV: Cell Overvoltage Fault UV: Cell Undervoltage Fault /COC: No Charge Overcurrent Fault /DOC: No Discharge Overcurrent Fault CC: Charge Protection Active /DC: Discharge Protection Inactive CE: Charging Enabled DE: Discharging Enabled Status = 11000111, 4.1 V, 0.0 C, 0.0 mA AccCurr = -5801.8 mAh -- CDH -- Status: SENSOR_SNAP_NOW State: PRE_OPS CDH Reset Count = 02B0 -- COMM -- Status: SEL_RF (COMM A) SEL_RX READY XCVR_CAL CAL = 26, POW = 08, RSSI = 5E -- Bryan Klofas, KF6ZEO Cal Poly State University

2008 AMSAT Board of Directors Election!
by Stefan Wagener 20 Jun '08

20 Jun '08

Hi folks, In the past, the candidates running for the AMSAT Board of Directors positions have used this forum to provide the membership with some thoughts and ideas about their intentions if elected. I would very much appreciate if that could happen again. Also, in light of the current discussion on LEO’s and HEO’s, it would be very helpful to see where the candidates are standing. Thanks, 73, Stefan VE4NSA

Drew, You have to forgive me since I never heard of kids day. Now that I know it is an ARRL adventure, I realize why nothing too news on the AMSAT sites. I am going to program my HT with the uplink and hopefully I can get a few kids on the air that might be at the hamfest. I think an ANS bulletin could have gotten more attention to June 21st.... 73, Dee, NB2F -----Original Message----- From: Andrew Glasbrenner [mailto:[email protected]] Sent: Friday, June 20, 2008 9:10 AM To: Interdonato, Dominick Subject: Re: Kid's day http://www.arrl.org/FandES/ead/kd-rules.html We've participated in KId's Day with AO-51 for about three years, twice a year. 73, Drew KO4MA -----Original Message----- From: "Interdonato, Dominick" Sent: Jun 20, 2008 8:51 AM To: ko4ma(a)AMSAT.Org Subject: Kid's day Drew, Is there a place I can get all the info for Kid's day on AO-51?? I looked etc. and no info except that it's kid's day. If while I'm demo ing tomorrow I can get a few kids to talk I would like to know what kid's day is all about. Seems that no one knows what this day is supposed to be operationally except diff freqs and easier to get a contact. Please advise or point me to the right page...

Also, please remember AO-51 will be reserved this Saturday for Kid's Day contacts, and utilizing the alternate uplink of 145.880 and a downlink of 435.300. 73, Drew KO4MA

Info Request
by Clint Bradford 19 Jun '08

19 Jun '08

From another forum - please reply directly to: siddhartha(a)siddharthajain.net I attended a presentation by Matt Ettus, N2MJI, at the Palo Alto Amateur Radio Association's monthly meeting about the Advanced Communications Package. The project sounded very interesting and as I remember, Matt said that the ACP project's goal was to send up these amateur stations on commercial satellites in the geostationary orbit so that it eventually, someday, gives a trans-global reach for amateurs with portable/handheld radios. This was supposed to be an alternative to the Eagle project. I got talking to a friend and fellow operator who used to be very interested in amateur satellite work and he was very interested in knowing more about ACP. Is there a whitepaper, wiki or some kind of documentation briefly describing the project? I looked at the AMSAT site and could not find much. Any pointers will be appreciated. 73, - Siddhartha WV6U Clint Bradford, K6LCS / KAF3359 909-241-7666

Satellite antenna question
by John Geiger 19 Jun '08

19 Jun '08

I have a kind of minimal satellite antenna setup: a 16 element and a 14 element, both horizontally polarized, with no elevation. I notice that on some passes I can barely hear the satellites, or not at all, and other times they come through strong. Would upgrading to a real satellite antenna system: circular polarization with elevation remove these variances in signal strength? With such a setup, would I have perfect copy on every sat pass, or does is the differences in signal from pass to pass something everyone lives with? 73s John AA5JG (ex: W5TD, NE0P) 6M WAS #1275, 6m VUCC #1260 2m VUCC #615, Satellite VUCC #129

Hi Andy, You have nothing to apologize for. You posting showed more balance and maturity than the ranting of the 3 or 4 "gentlemen" that appear on the list from time to time.
