MASAT-1
by Bruce Robertson 15 Feb '12

15 Feb '12

Had a blast collecting telemetry for MaSat-1 just now. I used object C, which was not correct for doppler. Judging by the point at which the signal ended on my clear horizon, I think it might be F or G. For those who are new to the software, I'd note that the strongest signal on the waterfall is the one that should be aligned approximately with the 575 Hz mark. It is quite tolerant of your being off by a 100 Hz or so, I'd say. I also think that the CW signal should be on the 1200 Hz mark (i.e., don't tune the CW to a typical CW tone, which is around 600 Hz). Does anyone know how close to the upper and lower marks I can set my filter on the TS-2000? 73, Bruce -- http://ve9qrp.blogspot.com

Masat website update - 'packets received' now working.
by Andy Kellner 15 Feb '12

15 Feb '12

Looks like the Masat team updated / fixed their website, too. Now when you go to the 'track our satellite' section, it actually shows the position of the satellite and - more importantly - the 'Packets Received' from each registered Amateur station ! So now you can check if the packet upload is actually working. http://cubesat.bme.hu/en/ Good stuff. Nicely Done, Masat team. Andreas - VK4HHH

MaSat Telemetry Software
by Andy Kellner 15 Feb '12

15 Feb '12

All, I got some answers from the team in Hungary and apparently the software is _in_deed_ automatically sending the packets to the server over there ! The 'offline' sign in the lower left corner has nothing to do with it: > Hi Andreas, > Thanks for the packets! > New TLE from Celestrak: > 2012-006C > 1 38079U 12006C 12045.91493796 .00003662 00000-0 10000-3 0 77 > 2 38079 69.4856 235.4820 0781498 42.5136 323.3856 14.05527418 208 > The automatic packet report works in background. > I checked the logs, and you sent us 561 packet online until now. > Regards, > Tibor Mezei Well there you go. Sent them 560 packets and didn't even know it :) And in another email: > Dear Andy, > Please try to use the telemetry softwares automatic packet sending. > It works for a lot of people. Actually the sign > "Offline" in the lower left corner of the telemetry window was shown > for a future improvement and shows something else. It is misleading, > so we will remove it in the next release. > Please answer to the ham(a)cubesat.bme.hu address where my colleague, > HA3PL Levi, who is more competent in these topics, will answer to your > further reports. > Sincerely, > Zsolt Várhegyi > Masat-1 Developer Team Still doesn't explain why the 'Server side logging' checkbox is unchecked _and_ grayed out. But I guess its all research software very much under development. Andreas - VK4HHH

I use Masat-1 decoder with a number of other stations all over the world. Please take a look into your folder where your decoder is installed. You may find files made daily like this: Masat-1_20120214.txt This sample contains a few frames from those I have received and decoded yesterday: PACKET 03 C6 03 19 C6 7B 00 00 3B 00 00 00 46 62 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 81d87f1ca520f3ec4bb16da39a689bb43d96a1d9 1329221453140 PACKET 04 C7 03 19 C3 70 0D 00 80 00 00 00 00 00 00 04 4F 80 00 00 00 00 00 00 00 00 00 00 00 00 00 00 1dcada218f5ce5cacf4642b70897f4e827a61412 1329221454984 PACKET 04 C8 03 1A AB 08 DB 08 80 08 1C 08 98 08 82 08 E6 FF F5 FF 34 00 E1 01 81 ED D4 F8 AD AD 00 00 7b9696597e5cceae99df54089978180fdfc1f3e7 1329221455968 The decoder software uploads this data to the Budapest command station automatically.

K7UGA report - Wednesday morning
by Patrick STODDARD (WD9EWK/VA7EWK) 15 Feb '12

15 Feb '12

Hi! I've planned my lunch today to coincide with the upcoming SO-50 pass at 1832-1845 UTC (a 27-degree pass, from my south to the northeast). That will be the only pass I can work as K7UGA during the daytime today. This evening, I am planning to make up for not being on last night and try two passes from home as K7UGA: VO-52 at 0252-0305 UTC (an overhead pass) SO-50 at 0310-0320 UTC (11-degree pass, from north to southeast) Tomorrow (Thursday, 16 February) morning will have some passes in the morning through midday that I should be able to work from home as K7UGA: VO-52 at 1444-1455 UTC (21-degree pass to my east) VO-52 at 1620-1632 UTC (26-degree pass to my west) SO-50 at 1900-1914 UTC (78-degree pass, from southwest to north) AO-27 at 1921-1928 UTC (13-degree pass to my east) Look for K7UGA around 145.910 MHz USB on the VO-52 downlink, but be ready to tune around if I am not there. If nobody is working me there, I will tune around and attempt to work anyone I hear on the transponder. After these passes, I plan to be on the road to the Yuma Hamfest, and may stop to work passes on FO-29 and possibly AO-7 in mode B late in the afternoon if I can safely get off the freeway. Then everything will focus on the Yuma Hamfest starting Friday at midday, although I may be able to work some mid- to late-morning passes before the hamfest officially opens. 73!

Masat-1 Telemetry Data
by Carl Rimmer W8KRF 15 Feb '12

15 Feb '12

I have been successful in copying both the CW and GFSK telemetry data and a log was generated but there is no indication as to whether it has been uploaded. Checking the website and each registered ham, I noted that they all say "0 packets received" so I must assumed that they are not automatically uploaded. Do we have to manually send the log files somewhere? If so, where? BTW, I am using 38079 (2012-006C) for Masat-1. I have not attempted to receive any of the others yet. 73, -- *Carl W8KRF*
