Hi Jeff, Both ISS and ANDE work fine using HBAUD 1200 U APRS VIA ARISS - Do not Connect, just go in CONVERSE mode and type for example ":Hello World" - ISS has sometimes delayed transmission - ISS may see a lot of uplinks in parallel, do you have a beam ? - ANDE-1 needs to be 'woken up', send a few packets and then it will reply - I use small doppler compensation A u 145.823 / d 145.827 B u 145.825 / d 145.825 C u 145.827 / d 145.823 (U = TX, D = RX) - 50W is more than enough for ISS, but also sufficient for ANDE - Antenna: I use a 2x6 elements beam (DK7ZB, see my website) Success & let us know !

...25 watts to an omni? 50 watts to a vertical? I have hit the ISS with 500 mW to an Eggbeater. But, G1OCN is right. When the ISS APRS transponder is on, there is ALWAYS traffic. It receives very well, and transmits a very decent amount of power. Jeff, when you say "vertical"...just what type of antenna are we talking about?

1/2 wave bypass for 432 amp?
by Bob Stewart 09 Dec '07

09 Dec '07

My 432 brick has about a 5 DB loss on the receive side. I think it's the relay, but getting to that thing would be a nightmare and I'm not even sure that they're still available. I ran across K3PGP's 1/2 wave filter, and I see that it is an adaptation of the pair of 1/4 wave lines in the old Heath HA-201 amp that they used for T/R switching. K3PGP's filter: http://www.k3pgp.org/432filter.htm HA-201 circuit at bottom of djvu file: http://bama.edebris.com/download/heath/ha201/ha201.djvu So to my question: would I likely encounter any problems using a pair of 1/4 wave coax lines with the diodes in the center to bypass the amp on receive? Has anyone done this sort of thing? I was thinking of putting it inside the case. Domenico, perhaps you? I see your call on K3PGP's page. :) Bob - AE6RV

ANDE de-orbit day guesstimate ?
by Henk, PA3GUO 09 Dec '07

09 Dec '07

Based on the ANDE de-orbit / height graph of USNA (http://www.ew.usna.edu/~bruninga/ande-ops.html) I inserted the heights for Dec 5 and Dec 9: http://home.vianetworks.nl/users/hamoen/pa3guo/ande_predict_09dec2007.jpg Based on the current keppler sets & NOVA calculations ANDE is today at 226 km. >From 225km to de-orbit the graph shows ~15 days, so de-orbit today + ~15 days = ~24 Dec ? Please note this is NOT a formal estimate from Bob nor USNA, it is just my personal guesstimate based on the graphs. Is there anyone that has taken a more scientific approach ?

Re: RS14/Oscar 21
by Andrew Glasbrenner 08 Dec '07

RS-14/AO-21 was not a satellite per say, but a package on a larger Russian satellite known as Informator 1. As I understand it, when the Russians were done with the satellite, they shut it down, which killed the amateur packages. Basically, it was beyond the amateur package owner's control, which was -not- AMSAT-NA by the way. I agree though, it'd be nice if it was still around, along with every other satellite we have lost. RIP AO-10, AO-13, AO-40, SO-35, RS10/11 and 12/13 especially! It just goes to show that satellites are of a finite lifespan, and we must continue to build and launch to stay in the satellite business. 73, Drew KO4MA -----Original Message----- >From: "John Marranca, Jr" <KB2HSH(a)amsat.org> >Sent: Dec 8, 2007 9:53 AM >To: amsat-bb(a)amsat.org >Subject: [amsat-bb] RS14/Oscar 21 > >According to the AMSAT Satellite Status page, RS-14/Oscar 21 was "switched >off". > >Several things perplex me about that particular statement. > >Firstly...I understand the economic idea of not being able to afford >something.

RS14/Oscar 21

According to the AMSAT Satellite Status page, RS-14/Oscar 21 was "switched off". Several things perplex me about that particular statement. Firstly...I understand the economic idea of not being able to afford something. When it is swtiched off, is it a FOREVER one way switch...or is it similar to when a FAX machine sleeps...and wakes upon hearing a CNG tone? If it can be revived, why hasn't it? If it could, is it a situation that could be lobbied for...? AMSAT cites that it was too expensive to maintain. Fine. How about tranferring ground control to another entity. The only reason I'm curious about it is because I fondly remember how WELL RS14/Oscar 21 worked on simple equipment. I had an Alinco DJ-120 and a Radio Shack scanner in college that worked pretty well with this bird the few times I got to play with it while it wa "ON".

Re: QUAGI vs HELIX vs QUAD
by John Mock KD6PAG 07 Dec '07

07 Dec '07

In some ways, it depends on which satellites one is talking about for this comparison to be that meaningful in terms of types of antennae. If i've figured things properly, comparing an RHCP helix against a linearly polarized Quagi is likely to get you a 3dB difference if the satellite is RHCP. Even if the satellite is linearly polarized, on an AZ-EL mount, RHCP may still be the winner, as my experience on an Arrow- equivalent antenna is that linear polarization tends to change from the beginning of a pass through the end (especially on AO-27). I figure about half of time on the average, the linearly polarized antenna is going have mismatched polarization. A better comparison would be a RHCP Helix against an RHCP Quagi. I have misplaced my copy of the article, but i think the article that inspired the antenna system that i built was based on the QST January 1990 article "Circularly Polarized Quagi Antennas for Space Communications". The drive loop is fed on two adjacent corners to obtain circular polarization. I modeled and then built a phased pair of quagi. The phasing harness had lots of coax in it, but the rest was fairly straightforward. http://www.qsl.net/kd6pag/nec/q436-5cp1q.html The modeled gain was 17dBc, and whether i believe that or not, what i do know is that i was able to work AO-40 QRP near apogee.with that antenna, not long before AO-40 went silent. I had also built a long helix out of copper tubing, but didn't really test it adequately. It was a bit heavy and rather unwieldy by comparison. -- KD6PAG (Networking Old-Timer, Satellite QRPer)

I wouldn't use those for anything. Wayne W9AE replies: I've soldered dozens of "two piece" N connectors in the last 10 years. I've NEVER had a connector pull off, but I also haven't tried pulling on the connector with all my strength. The connectors have survived years in the elements, including cables hanging vertically from my mast-mounted preamps, supported only by the connector. I mostly use flexible 9913 or LMR400UF, and just clip a few strands of the center conductor to get it to fit in the connector.

by John Mock KD6PAG 06 Dec '07

06 Dec '07

> I would've like to use N connectors, but the equipment has PL-259, and > I don't want the losses from an adapter. Because of the reputation of PL-259 connectors above 2 meters, i doubt you will find commercially made feedline with high quality coax and PL-259 connectors. But unless you can completely keep water out of your fancy coax (or even 9913), after a modest number of years, it may end up having worse loss than RG-8... And the popular wisdom is that even N-connectors are hard enough to make water tight. Here's a compromise: Use N-connectors outside, where you NEED things to be weather-resistant, and use whatever-matches-your-radio inside. The only problem with that is you'll probably have to make this feedline yourself, or maybe find someone locally who can do it for you. By the way, a satellite radio having PL-259 for 2 meters and N-connector for 70 cm may not be such a bad thing; it makes it harder to plug in the wrong antennas. Nonetheless, you might also think about which is likely to have greater losses at 70cm and above, a homemade PL-259 plug or an adapter to an N-connector. 73's and good luck! -- KD6PAG P.S. N-connectors and PL-259's share this characteristic: Some people swear by them and other people swear at them...

ANDE - ISS dual hop?
by Robert Bruninga 05 Dec '07

05 Dec '07

ANDE is catching up to ISS. Now at about 0100z on the 5th, ANDE's footprint is just touching ISS's. And ISS is on packet on 145.825 just like ANDE. Over the next several hours, ANDE will get closer to ISS and then move out in front. I suspect that ISS has no chance at hearing the weak ande, and ANDE might not hear ISS, but the best chance will be monitoring ANDE's downlink for any double hop packets via ISS. Since both spacecraft respond VIA ARISS, then a double hop packet might try the path UNPROTO APRS VIA ARISS,ARISS. A slightly more efficient path (shorter packet) might be APRS VIA WIDE2-2. See the ANDE-OPS web page: http://www.ew.usna.edu/~bruninga/ande-ops.html Good luck! Bob, WB4APR

Hi All, The ARISS-Europe L/S band antennas are now mounted on the outside of Columbus which is safely located in the cargo bay of Shuttle Atlantis prior to its scheduled launch tomorrow. The flight will be covered by NASA-TV as usual and their 150kb video stream is also available over the internet. For this flight ESA are also relaying the program(me) over the Atlantic Bird 1 satellite for viewers in Europe who have a FTA satellite system. Details from ESA are given below. As the antennas are on the "bottom" of Atlantis they will not become visible until it has been completely removed from the cargo bay prior to mating it with the Harmony module of the ISS during the first EVA on flight day 4. Exciting times! 73 Graham G3VZV The next Shuttle mission to the ISS, STS-122 with European astronauts > Leopold Eyharts and Hans Schlegel on board, has now been confirmed for > launch at 21.31 GMT on 6 December from Kennedy Space Centre, Florida.

Basic Packet How-To for ARISS and PCSAT
by JoAnne Maenpaa 04 Dec '07

04 Dec '07

Hi everyone, I put together a very basic overview of how to get started with packet via ARISS and PCSAT-1: http://home.comcast.net/~k9jkm/ARISS_Packet_How_To/ Please take a look and let me know what needs to be fixed or added? I've been 'elmer-ing' a few hams about ARISS packet and my web content is pretty much based on what I've been asked about. Its not intended to be a comprehensive AX.25 packet or APRS guide. Most hams I've worked with had basic packet knowledge from back in the 1990's but now wanted to know what else they had to do to get on 145.825 MHz space packet. There will always be plenty for you to learn ... hopefully my quick-start guide will get you up and running for your first QSO. -- 73 de JoAnne K9JKM k9jkm(a)amsat.org

Agree ... and HELP !!!.

Hey Bob, That's a great !!! idea ... I wish !!!! I knew how to do it. Emily, who wrote the program "disappeared" into the "Second Life" virtual world over a year ago and has not been heard of since!. She used to send me a cookie every December to reactivate the annual editing privilages I had from my computer. I have a copy of the cookie but have no idea ! where it should go to activate the program again. Last December I just messed around with it and somehow managed to get it into the right place by a fluke! ... sheer luck ... this December, after messing about all day I can't find out where it should go. Needless to say, I am most definately *NOT* an IT guru. I'll bat this mail to both reflectors Bob just in case somebody recognises the problem and can advise me how to correct it. 73 John. <la2qaa(a)amsat.org> From: w7lrd(a)comcast.net To: la2qaa(a)amsat.org Subject: Re: [amsat-bb] AO-7 ...

AO-7 ... N1DID & K9CIS note.
by John Hackett 04 Dec '07

04 Dec '07

Hi All, It's December again ... (ho -ho-ho) ... and consequently my administrative privilages for The AO-7 Resource Page log have expired. (This means I can no longer edit the mistakes) Emily N1DID hasn't responded to my mails so the log will probably very soon get out of hand again. Frank (K9CIS) on orbit 51248 at 23:27 you've logged K3SZH twice for the same QSO. Each station can still edit their own entry (but nobody else's) by clicking on the hourglass at the left of your entry. A new screen will pop up and you can just correct any mistakes. PLEASE !!! be careful to enter the correct data because if you don't notice your error it will soon throw the log statistics out of whack and defeat the entire object of the log ... which is an ACTIVITY log *NOT* a contest log. I have administered the log for three years but am now concentrating on a different long term activity regarding AO-7 which, hopefully, will benefit the entire amateur satellite community - commencing in the spring of 2008. A request to the ANS editor regarding careful entries in the log and how to edit it would be very much appreciated. 73 John. <la2qaa(a)amsat.org>
