[amsat-bb] Re: ARISSat-1 over West Malaysia
Hello Sion, Thank you for the reception report. 1) I have forwarded your request to store the callsign and enable forwarding to the ARISSatTLM software developer. 2) Good question. We look forward to your help in determining this. We are anxious to optimize the software, once we get real world reception. Our initial efforts to maximize lead to tradeoffs, so rather than pursue unknown cases we decided to wait until we got real data from the satellite in orbit. 3) The BPSK data is sent every time the transmitter is on in Low Power and High Power. The transmitter is turned off for 2 minutes after the 30+ sec on time. 73, Gould, WA4SXM - Original Message - From: "Sion Chow Q. C.

[amsat-bb] Re: ARISSat-1 over West Malaysia
Hi, 2. The program does allow you to enter the callsign and forwarding permanently. However, it doesn't always work. : Earlier this year, I had it running with no problem on my XP machine. I bought a new WIN7 machine, and the install seemed to go well, except that it complained there was no ??? directory to install something it needed. I don't recall the exact wording, but I read the error message and manually created the directories it wanted in a fake user profile on the C drive. After helping it, the installation seemed to go normally. (It was installed, and is run, from a full administrator account.) However, I found the same problem you have. I had to reenter the data every time it started. There was also a problem with some of the associated panes not displaying properly unless they were maximized Here is what I eventually did. I tried reinstalling the program several ways, but no help. Next, I tried running the RESET-CONFIG-FILE.BAT in the ARISSATTLM directory, which deletes the configuration file. No change, even after running the program, and then another clean reinstall. From the batch file, the configuration file is stored here: "%USERPROFILE%\DESKTOP\ARISSATTLM\ARISSatTLM.CFG" I ran a global search but did not find the ARISSatTLM.CFG file. Then I went to the directory, empty, and manually created an empty file with that name. Started the program, but no help. Finally, I reinstalled the program over itself. That fixed it! This also fixed the issue with the various program panes not displaying as they should. It appears that on some version and configurations of WIN7 there is a problem creating the file. I have WIN7 Pro 32 bit. It is configured to store the OS on C drive, and the User data on F drive. That has confused at least one other program. So make certain you have an ARISSatTLM.CFG file. If not, create and empty file of that name, run the program, and if it is still not working, reinstall it over itself. That worked for me, though there must be a more efficient way to get there. Let me know if it solves your problem. 73s, Alan WA4SCA -Original Message- From: amsat-bb-boun...@amsat.org [mailto:amsat-bb-boun...@amsat.org] On Behalf Of Sion Chow Q. C.

Sion, >1. Is it possible to have the callsign and forwarding telemetry option >always set in ARISSsatTLM? This way, we do not have to manually enter >the callsign and enable telemetry forwarding each time the program >starts up. When you close ARISSatTLM, did you push X button on right upper corner? This way could not save the setting in config file. Set your callsign and select File - Exit to close ARISSatTLM. Then the config file is updated. You will find your callsing is keeping next start up. I find this manner just today. 73 Masa JN1GKZ >Dear All, > >It was great to receive ARISSsat-1 over West Malaysia during 5th >August 2011, 0223 UTC pass.

[amsat-bb] Re: ARISSat-1 over West Malaysia
Sion, Glad the simple solution worked. For others reading this, if the simple solution does not work, try the complicated one I gave. I always use the File | Exit method of closing a program for exactly this reason. In my case, it didn't work. 73s, Alan WA4SCA -Original Message- From: amsat-bb-boun...@amsat.org [mailto:amsat-bb-boun...@amsat.org] On Behalf Of Sion Chow Q. C.

Tuning the CW beacon to 500 Hz automatically centers the BPSK1000 signal at 1500 Hz. I didn't put in a whole lot of frequency tolerance in the BPSK-1000 demodulator because the signal is 2 kHz wide from null to null and it would begin to be chopped off by the edges of the receiver's SSB filter. So while you should ideally tune to +/- 100 Hz you might go to +/- 200 or even 300 Hz and it will *probably* still work, but I wouldn't go too much wider. Go ahead and experiment; I'd be interested in any reports on how well my demodulator (which is incorporated into both the Windows and Mac telemetry programs) tolerates tuning errors. Frequency acquisition and data synchronization are the hardest parts of any digital demodulator, and I'd like to know where there's room for improvement. 73, Phil ___ Sent via AMSAT-BB@amsat.org.
