SSTV via ARISSat-1 RADIOSKAF-V KEDR
by Farrell Winder 20 Dec '11

20 Dec '11

The FM section of ARISSat was sending very strong voice and SSTV signals on 2 passes over Eastern USA Dec 18. Hoping that some stations will try experimenting with voice and SSTV through the Transponder 435.750 LSB up listening 145.930 MHz USB +/- doppler down. I will be listening for contact on the Eastern USA pass today AOS 20:19 UTC . Do not believe there are many days left for ARISSat-1 to be in orbit, I show it is down to about 172 miles altitude according to Nova tracking with latest Keps.. Farrell Winder, W8ZCF

ISS BBS
by Kevin Deane 20 Dec '11

20 Dec '11

The ISS Maildrop is great for people in low population areas. I found out the hard way about using it in the US. Now I and others on the west coast are suffering because a certain someone keeps logging in EVERY pass and is not even holding the connection. The email address is no good on QRZ. ARRGG!!! Anyway it still is fun to make Qso's on the Digi just thought since there are not as many birds up there to play with there might be more activity on the ISS. Have not heard much on FO-69? Are people workin that? My radio is in the shop so I have been off the air and only have a 5watt deaf dualbander... :( Kevin KF7MYK

AO-7
by Rsoifer＠aol.com 20 Dec '11

20 Dec '11

The AO-7 pass just concluded here reached maximum elevation of 31 degrees to the wesf of my QTH (DM41lu), and the satellite was in Mode V/A (also called Mode A). With about 100 watts EIRP my downlink signal was RST 589 but I had the passband to myself. Nothing but me and the beacon, which was RST 579. My V/A receiving system at this QTH is nothing elaborate, just a Ten-Tec Argonaut V radio and a Hy-Gain AV620 vertical antenna. AO-7 is likely to be in Mode V/A for much of SKN. Hope to work you there. 73 Ray W2RS

ARRL Teachers Institute on Satellites Today
by JoAnne Maenpaa 20 Dec '11

20 Dec '11

Just a reminder for today ... SB SAT @ AMSAT $ANS-352.02 ARRL Teachers Institute Plans Satellite Demo on December 20 AMSAT News Service Bulletin 352.02 >From AMSAT HQ SILVER SPRING, MD. December 18, 2011 To All RADIO AMATEURS BID: $ANS-352.02 Satellite operators are invited to listen for ARRL Education and Technology Program Director, Mark Spencer, WA8SME on the afternoon pass of AO-27 (and possibly other satellites) on December 20 as he conducts an operating demonstration from the ARRL Teachers Institute at Mississippi State University. Satellite passes on December 21 are planned as backup operating times. Mark will be covering topics regarding using space-borne systems in the classroom. He says a major part of that unit is demonstrating ham satellite contacts. Mark will be using the call W1AW/5 for the pass. If you'd like a QSL for the contact, send an e-mail to him (mspencer(a)arrl.org) and he will make sure you get one. Find out more about the ARRL Teachers Institutes on-line at: http://www.arrl.org/teachers-institute-on-wireless-technology.

ARISSAT-1 Pass Over SoCal Tuesday
by Bryan Herbert 20 Dec '11

20 Dec '11

If these keps are correct then hams in DM04rj will be treated to a 53 degree pass from ARISSAT-1 around 2331 UTC (331pm local) this afternoon (Tuesday). Here in the Santa Clarita Valley, 30 miles north of Downtown Los Angeles, we are surrounded by 3000-6000 foot peaks. We have not seen a pass above 20 degrees since mid-October. To date I have only managed to successfully receive ARISSAT-1 twice, I'm hoping this afternoon I will be able to receive a SSTV image, decode some telemetry or contact someone through the transponder. -- Bryan Herbert - KE6ZGP Newhall, CA.

Re: APRS on Bernuda and Atlantic
by Howie DeFelice 19 Dec '11

This is a good reason to use APRS on Cubesat for telemetry. Imagine if even half of the cubesats launched transmitted their telemetry as APRS packets and simultaneously operated as APRS digipeaters. We could have a global constellation of APRS repeaters feeding the terrestrial internet backhaul in short order. This is not only great for us but a major advantage for the folks running the on board experiments since: 1. It provides a standardized method of formatting and transporting the science data2. Allows the science data to be automatically forwarded to a collection server allowing greater access to the raw data3. Every APRS igate around the world becomes a 24x7 collection node We in turn get a worldwide messaging tool. Imagine being able to notify the whole world at once that you just came up on SO-50 in that really rare grid :) Oh well, at least I think it's a good idea :) Howie- AB2S

Howdy, I've been to the weather station at the east end of the runway on St. George's. http://www.weather.bm They have webcams, Internet, power, etc. Perhaps a convincing proposal could be made to them in the interest of APRS and Meteorology...HI HI GL 73, Guy - W6MSU > Date: Sun, 18 Dec 2011 14:11:37 -0800 (PST) > From: Jeffrey Koehler <jeffk13057(a)yahoo.com> > To: "rhyolite(a)nettally.com" <rhyolite(a)nettally.com>, > "bruninga(a)usna.edu" <bruninga(a)usna.edu>, "amsat-bb(a)AMSAT.Org" > <amsat-bb(a)amsat.org> > > How about maybe the buoy system? > > > http://www.ndbc.noaa.gov/rmd.shtml > > > > 73, Jeff WB2SYK
