DX on satellites
by Jim Danehy 12 Oct '08

12 Oct '08

Congratulations to Jay AA4FL on his DX accomplishment. I am a relative newcomer to the satellite game. I have been lucky to have worked just about every DX entity that has come along for the last 50 years. I find that there is little interest in CW on the satellites. That is not surprising since there is little interest in CW in the HF spectrum. I enjoy both DXing and ragchewing. I have watched many FO 29 passes over Europe where my signal is good copy but no activity. Not surprising since it is 3 AM in Europe. If anyone in Europe would like to try a schedule with me on FO 29 I would be interested. I am primarily a CW operator too (my preference). Every year I see many DXpeditions to various spots in the Caribbean for contest activity. It would be great if these groups would get on the satellites and spice up the birds. I have thought about going to OX (Greenland) next Summer where I could access both Europe and a lot of North America on both the FM satellites as well as those with SSB/CW. Is there any real interest in working DX (rhetorical question) ? I have heard a couple of Central American stations get ignored on the FM satellites while stations swap reports for the umpteenth time between themselves. FO 29 gives plenty of DX capability but rarely have I heard it utilized. I work Europe on AO 7 but FO 29 appears to be better in my opinion. Anyone interested in a sked from NA to EU ? Any interest in working OX (Greenland) ? 73 Jim W9VNE EM79tb

CW on the satellites
by Frank A Cahoy 12 Oct '08

12 Oct '08

Hello Jim and other CW addicts, I too, have been a CW junkie all of my ham radio years. I was first licensed in June of 1960. I can't claim being a total CW operator but that is certainly my operating mode of choice. I did a quick scan of my last five log pages. (I keep a hard copy but I also enter my QSOs into log-EQF so I have a double logging system.) I found only 10 fone contacts out of about 125 total Qs. When we had AO-40 up and running quite well I gave up on HF and devoted all my efforts to chasing DX on that bird. I did actually make nearly 1000 Qs but I will sadly admit that about 90% of them were on fone. It's not that I wanted to work fone but there was very, very little everyday CW operation on the bird. Several expeditions made good use of their time by operating both CW and SSB. Since I was chasing hard for satellite DXCC I worked whatever DX I could hear on whatever mode they were using. My first satellite QSOs were via RS-12 and they were on CW! My first QSOs on AO-10 and AO-13 were also on CW. (Wish I could have been interested in the birds when 13 was in it's prime.) I too, operate , just for the fun of it, in some DX contests but generally have much more fun doing the CW versions. I often wonder if those high speed contesters I work can really copy as fast as they send. I can because I still log on paper first and then e-log later. I too, work Field Day whenever possible but make the stipulation that I get to do the CW operating. No one has ever challenged me for that. Jim, I too am 70 years old and I'm seriously wondering if I'll live long enough to see another HEO bird in orbit. At the current rate of putting such birds into orbit the chances of my living long enough to chase DX on a satellite again seem, as the saying goes, slim and none!! I love chasing DX but the challenge of doing it via ordinary HF is certainly less satisfying than working Cocos Keeling Island with less than five degrees of elevation at both ends and doing so through a hole in an Elm tree across the street from my satellite antennas. BTW, I need only North Korea to have them all on HF but I have only about 120 worked via satellite so the challenge remains for me via satellite but without an HEO bird it's only a vague dream. I favor, at the moment, 30 meters only because there is no fone allowed on this band. I hear quite a few 'struggling" CW operators there but I have to give them due credit for trying. I don't currently operate 40 meters but I too have often called CQ on 30 without any answer whatsoever. Interest in CW is waning and doing so at a fast pace. Jim, let me know if you'd like a sked for a CW QSO. Seems we have much in common. Please promise not to send faster than 25/30 WPM. That's OK in a contest or for a DXpedition but 20 WPM makes for a much more enjoyable rag chew!! Long live CW both on HF and satellite but us old "die hards" can't continue for much longer. Admittedly, we need help. Right, Jim? 73 to all.

SSTV Decoding on OS X
by David Johnson 12 Oct '08

12 Oct '08

Hi Folks, For those of us the Apple machines, you can use Multimode from BlackCat Systems: http://www.blackcatsystems.com/software/multimodeOSX.html I used it this afternoon to decode images from the AO-51 testing. Unfortunatly I missed the messages about the ISS until it was too late in Europe :-( Have a great time catching the images. 73 Dave, G4DPZ AMSAT-UK Committee Member AMSAT-NA Life Member

ARISS images
by John Marranca, Jr 12 Oct '08

12 Oct '08

Good Afternoon, all. What fun receiving the images from the ISS! At the start of the 1819z pass, there was a short DTMF burst that was so loud that I though one of the locals was doing it. After hearing "RS0ISS" in CW, I received the images! The strength of the signals reminded me of what U5MIR sounded like in the 90's. Thanks to the ARISS team for putting this together. 73 de John KB2HSH -- _______________________________ John Marranca, Jr PBX Technician/Shop Steward CWA Local 1122 BN Systems, Inc Orchard Park, NY (716)972-2006

432 MHz linear amplifier
by Glen Zook 12 Oct '08

12 Oct '08

At the suggestion of the AMSAT Treasurer I am posting this request to the bulletin board: What I am looking for is a solid-state 70 cm linear amplifier that has an input of no more than 250 mW and an output of at least 10 watts and 25 or more would be even better. The frequency range needs to be from 432 MHz to 435 MHz or wider. I am familar with a couple of kits including the one from Australia that definitely has the best price. However, I am also looking at building my own but have not found a suitable construction article here on the Internet using both "google" and "yahoo" as search engines. Nor have I found a suitable amplifier in the issues of Ham Radio Magazine and 73 Magazine that I have. What I am looking for is something that has a board "layout" (I am definitely able to reproduce a board). I do have a "fair" number of suitable transistors and other parts available that can be used. Also, if someone has a suitable linear amplifier (this is for both CW and SSB) at a reasonable price or else for trade I would definitely be interested. I have all sorts of things to trade including tubes (receiver, transmit, higher power), components, and a few "boat anchor" items. Since I am on a "fixed income" (Social Security disability) I definitely do have to be careful as to how much I spend on such things (my wife would definitely take severe action against my bodily health if I spend too much). What I need the linear amplifier for is a Microwave Modules 432 MHz transverter. The 10 watt linear amplifier board is missing and the basic exciter only puts out 250 mW. Now I did know the amplifier was missing before I traded for the unit so that was not a surprise. The transverter works very well but the output power is not sufficient to really do anything with and is way too little to drive my 4CX250B amplifier.

HRD for SSTV?
by Mike Ryan 12 Oct '08

12 Oct '08

I see hints on the postings that HRD or DM780 can do SSTV. I've hunted around a bit and cant quite see any options like that though I see RTTY, PSK31 and others. What am I missing here? Mike WB1AAT
