At one time I was seeing updates on new SAT projects. For some reason when I had my computer hard drive problem I stop seeing such updates and cant seem to find the URL now. Can someone please pass it to me again? And any word on what is happening on a replacement for AO-40 other then lack of funds. Thanks, all John, W0JAB EM48lk

Orbital Decay and Atmospheric Density
by John Heath 05 Dec '11

05 Dec '11

Hi Gents, I have been working on an excel spreadsheet regarding ARISSat-1, orbital decay and atmospheric density. Its a small workbook with some calculations and a chart. The idea is to work out the volume that ARISSat-1 sweeps through per orbit, then calculate the mass of atomic material it will colloid with. Math is NOT my best subject . Is there a math guru on the list willing to take a quick look and tell me if I am on the right lines. Let me know and I will send it off list. Thanks John G7HIA

Hi John, The UK and the mid-west were mutually visible in the morning almost the entire month of November, 1997, via AO-10. There was a gap for a couple of weeks in December, 1997, but mutual visibility returned for the 2nd half of January 1998 into Feburary 1998. RS12/13 made morning passes visible to the mid-west roughly every other week starting October, 1997 to March of 1998. (didn't calculate passes beyond that) However, if you were tuning around in the FM mode and found an SSB signal loud enough to get your attention, I think you probably heard RS12/13. Do you remember how long you heard the signal? (a couple of minutes or a half an hour or more). Was the signal strength steady or was there a slow deep QSB? 73, Armando, N8IGJ >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> Date: Fri, 2 Dec 2011 13:58:52 -0600 From: John Geiger <aa5jg(a)fidmail.com> To: AMSAT-BB <amsat-bb(a)amsat.org> Subject: [amsat-bb] HEO history question Message-ID: <CAFq43LZDtAvUcUDYzFtYxe4kG0XBQK_iaGNKkR6KE0tB=H1mYw(a)mail.gmail.com> Content-Type: text/plain; charset=ISO-8859-1 Back in late 1997 or early 1998 I was using a Kenwood TR9130 on 2m SSB. One morning I was tuning from the FM to the SSB portion of the band, and heard a station just below 146mhz. I tuned them in, and it was a station from Wales! Obviously going thru a satellite as the 2 meter conditions weren't that good that morning. I am now wondering what satellite it probably was. Hearing it was enough to motivate me to eventually get into satellite operations-that took a few years though. Anyways, what satellite was I probably hearing? I am guessing AO10 or AO13 but were they operational at that time? 73s John AA5JG

Lets move forward

Unfortunately AO51 is gone, my thoughts are to get the P3E project moving and the thing in the air so we all can continue to enjoy this facet of the hobby; Can any one tell me what is the status of P3E? The web page appears to be not updated for some time. So I guess for those of you that have stood in their backyard and worked AO51 with a HT and a Arrow for many years what was that worth to you? I know that there a many in Australia that have hogged the thing let alone world wide, so how about putting your short arm in your deep pocket and donating to the project, stop all this bickering and move forward all this arguing that I've been reading is so counter productive to the cause. Remember gentlemen it's just a Hobby. Frank H Woolfe; Dip EE,VK5KV.

>> ... and with only one SSB and one FM sat left ... We have ARISSat-1. And the ISS. And SO-50. And AO-27. That's four FM birds workable right now. Yes - we need more satellite projects launched. But monitoring and working FM birds is still a viable part of our hobby! Let;s at least count the nunber available properly! (grin) Clint, K6LCS http:/www.work-sat.com

Very creative and efficient use of color. Never thought of using the screen color to match the band. Now I will need a portable heater for the Minnesota winter...guess I could mount the antennas to an ice house and go quasi-maritime mobile as soon as the lakes freeze over :) Dave David Donaldson Burnsville, MN WB7DRU Navy MARS: NNN0AXK Grid: EN34ij Sent from my android device. -----Original Message----- From: David Palmer KB5WIA <kb5wia(a)amsat.org> To: "Trevor ." <m5aka(a)yahoo.co.uk> Cc: AMSAT BB <amsat-bb(a)amsat.org> Sent: Sun, 04 Dec 2011 10:20 AM Subject: [amsat-bb] Re: Articles on Getting Started on SSB Sats Hi Trevor, Just FYI, I've posted a detailed description of how to set up a station for working the SSB (and also FM) sats on my web page at: http://kb5wia.blogspot.com/2010/10/satellite-portable-station.html The station consists of twin Yaesu FT-817ND radios and an Elk antenna, and a number of us in the community are using such systems for portable and home ops on SSB sats with very good success.

Next one ready to launch will probably be the AMSAT-UK 1U cubesat 'Funcube' with a linear transponder. Local to you will be Fox-1. Lets hope it qualifies for launch funding from an educational grant. Sadly the standard launch costs for P3E look to be impossible to fund, so we need a goverenment to step in. Not sure the European economy will support that as it has many problems at present. Thanks David SwissCubesat is interesting, but there are no ham freq projects in the pipeline here or at AMSAT-UK. -----Original Message----- From: Michael Hatzakis <lists(a)hatzakis.net> To: amsat-bb <amsat-bb(a)amsat.org> Sent: Sun, 4 Dec 2011 20:46 Subject: [amsat-bb] sats to support
