[amsat-bb] Re: Spam through amsat.org
A significant fraction of the spam I get on my primary email account comes by way of the amsat.org email reflector; by my count, 18 of the 76 spam emails I've received in the last day. Same here. I stopped using my amsat.org address about a decade ago because it was so badly spammed. It is still a valid address but it forwards to a separate address on my mail server. I check it every few days. These days, most of the spam is in Chinese. Only reason I keep it at all is because that is the address used on several very old references that I did and I get E-Mail regarding those now and then. snip I wonder if it would be possible to set up some sort of auto-responder on amsat.org so that instead of just forwarding email, returns a message to the sender with a non-machine-readable image of the user's actual email address, possibly accompanied with a sound file with the same information for anyone with impaired vision. Spammers couldn't handle it, especially since most don't even use valid return addresses. But any real human could resend his email directly to its destination. An interesting idea for getting around the spammers... Almost any of the autoresponders do block most of the spam, but some legit users will also get blocked. 73 - Jim Walls - K6CCC j...@k6ccc.org Res: 626-914-4641Ofc: 818-548-4804 Cell: 626-482-0927 ___ Sent via AMSAT-BB@amsat.org.

Patrick I have not been satellite active for several years (mostly because of no birds to actually talk through for more than 3 seconds at a time). LOTW was fairly new when I stopped operating satellite, but at that time the general comment from those that were using LOTW was that particularly for satellite operations, LOTW was such a pain to use, and really did not support satellite ops without putting in incorrect data (it did not understand our cross band operation or that there are actually more than one satellite in use). Maybe someone who is using it currently can advise if works better for satellite operations now. One of these days I will get back on the birds, but I do have several thousand satellite QSOs that I could log from years back if there were really any reason to do so. -- 73 - Jim Walls - K6CCC j...@k6ccc.org Ofc: 818-548-4804 http://members.dslextreme.com/users/k6ccc/ AMSAT Member 32537 - WSWSS Member 395 ___ Sent via AMSAT-BB@amsat.org.

I use Nova for windows and it will tell how old the keps are for the selected satellite by selecting AutoTracking Summary. That resulted in: Satellite name : OSCAR 10 Catalog number : 14129 Keps age : 1174d,03hr Next AOS : Location : Glendora, CA Latitude : 34° 07' 00 N Longitude : 117° 51' 00 W Algorigthm : G3RUH AutoTracking : Disabled The 3rd line shows the age of the keps. Yes, those really are 3 1/2 years old... If you look at a TLE file, the epoch time is the 3rd element in a 2 digit year followed by the 3 digits before the decimal and a bunch after the decimal point. So in the TLE below, the epoch time was 32.75507474 days into 2006.

Well, maybe not, I don't know what the maximum USb cable length can be. Remember that there are USB over Cat-5 devices that can carry USB much farther than a native USB. We are using a bunch of them at work. We're only trying to get about 75 cable feet, but they are supposed to work much farther than that. -- 73 - Jim Walls - K6CCC j...@k6ccc.org Ofc: 818-548-4804 http://members.dslextreme.com/users/k6ccc/ AMSAT Member 32537 - WSWSS Member 395 ___ Sent via amsat...@amsat.org.

The uplink or downlink or both? Or nothing since the frequencies are well known (at least on the FM birds). I had custom QSL cards printed for satellite operating. You can see pictures at the URL below. On the satellite card, the box right below the middle C of my callsign is Satellite and mode. I printed the satellite and operating mode - for example: FO-20 V / U. The next box was the operating mode - for example: SSB. I made no attempt to print the exact frequency - especially since it changed throughout the contact (I spent most of my time on the linear birds). http://members.dslextreme.com/users/k6ccc/QSL.html -- 73 - Jim Walls - K6CCC j...@k6ccc.org Ofc: 818-548-4804 http://home.earthlink.net/~k6ccc AMSAT Member 32537 - WSWSS Member 395 ___ Sent via amsat...@amsat.org.

[amsat-bb] Re: Starter antennas
Jacob Tennant wrote: I have a set of M2 loops antennas for 2 meters 70cm and from reading their website they state that they are good LEO antennas. So I was wondering what the consensus is from anyone that has tried them. I understand that they won't be as good as a CP beam setup on a az/el rotator, but since I have nothing up as of yet hoping they will at least let me get started, was also hoping to use them for a mobile satellite setup as well... Jacob, They will work, but understand that you will be dealing with a VERY WEAK signal. In my opinion, not the best for a starter antenna. An experienced operator who knows what they are getting into, and is willing (or desiring) the extra challenge can do fine with them. I have used a set of those loops for mobile operations, but I also have thousands of satellite QSOs in my log, and I know what I can and cannot do with them. -- 73 - Jim Walls - K6CCC j...@k6ccc.org Ofc: 818-548-4804 http://home.earthlink.net/~k6ccc AMSAT Member 32537 - WSWSS Member 395 ___ Sent via amsat...@amsat.org.

Bruce Robertson wrote: In a recent conversation on this list, I did the math and conservatively estimated that 125 1U cubesats could be launched for the current quoted price of a HEO launch alone. The more I think about this digital cubesat constellation proposal, the more I see its merits. I guess that would be if you had the slightest interest in digital satellite operation. Personally I have absolutely ZERO interest in digital satellite operation, only very little in the single channel FM birds, a lot more in linear LEO birds, and even more in linear HEO birds. For the most part, I don't care about DXing, but actually being able to talk to someone for more than a few minutes is rather nice. I will admit that I was happy to get Africa confirmed to complete my Satellite Worked All Continents a few years ago - only to have the ARRL lose the cards. -- 73 - Jim Walls - K6CCC j...@k6ccc.org Ofc: 818-548-4804 http://home.earthlink.net/~k6ccc AMSAT Member 32537 - WSWSS Member 395 ___ Sent via amsat...@amsat.org.

It has OSCAR printed above and slightly to the right of the large A of WAS. The number is #285 and dated 30 July 2001.
