Hi AMSATs, For some longer time I have been looking for a way to get a stand-alone real-time satellite tracking system, without the use of a dual-core, GHz speed power consuming computer :o) To my suprise I didn't found much, only one design called trakbox which can be found E.g at the following tapr website: http://www.tapr.org/kits_trakbox.html Unfortunatly it is not available anymore, and the mean reason I guess is the outdated components. I found out that the design originates from JAMSAT. Maybe someone has data (schematic, PCB layout, source code) of this design ? I wonder with todays highly integrated microcontrollers if there is some modern kind of real-time-tracker available ? I am looking for a system that works just seconds after switching on the power supply and not something that first has to boat 15min and needs a mouse to work. 73, PE1RAH William Leijenaar www.leijenaarelectronics.nl --- Send instant messages to your online friends http://uk.messenger.yahoo.com ___ Sent via amsat...@amsat.org.

[amsat-bb] AO-51 mode change
AO-51 is back to it's normal configuration, 145.920/435.300 repeater at 510mw, and 1268.700/435.150 BBS at 540mw. The digipeater is on, and I apologize to our Japanese friends who are fond of using the digipeater that we have neglected to make sure it stays on. The BBS is set to a slightly higher than normal power to assist with collection of background WOD (whole orbit data) for a few days. Later this week we will attempt to flip the spacecraft for the first time using the reversible magnet. This should result in a slightly better downlink in the Southern Hemisphere, and slightly poorer in the Northern Hemisphere. Careful, calibrated measurements pre- and post- maneuver are welcome to ao51-mo...@amsat.org.

William -- It depends what you mean by tracker, since the word is a bit widely used in English. It could mean 1) a device that, in response to az/el values submitted on a serial line, controls antenna rotors to track a satellite, or 2) a device that calculates those az/el values (as well as downlink and uplink frequencies, e.g.), or 3) something that does both of these tasks. There are many commercial and one-off instances of #1. Trackbox above is an instance of #3, though I don't believe it is still being kitted. The LVBtracker is best known as an instance of #1 above, but in fact the latest version is an example of #3 above. It is available from AMSAT-UK as a kit, and from AMSAT-NA as a completed product. If you'd like to explore an extremely low-power and small footprint device that will do #2 above, you might want to consider the qrpTracker libraries and applications I've written and ported for the Arduino platform, available at http://code.google.com/p/qrptracker/ with a website at http://sites.google.com/site/qrptracker/ I think hobbiests might find this easy to work with because the various building blocks -- like Plan 13 tracking code, TLE-storage and -access routines and rig-control activies -- have been packaged into C++ classes. Moreover, the Arduino hardware is ubiquitous, standard and relatively cheap. My youtube video demoing how this code and hardware could be used onboard a satellite to save power made the rounds a couple of weeks ago: http://www.youtube.com/watch?v=QSUK7Jq3LCY In a day or so I hope to post a video of the same device doppler-tuning my FT-817. The long-term terrestrial goal is to provide a satellite-selecting and doppler tuning 'dongle' for this and the TH-D7A. 73, Bruce http://ve9qrp.blogspot.com ___ Sent via amsat...@amsat.org.

[amsat-bb] Frustration
I've been trying to get my receive setup going the last few days but I'm having horrible results. I have my 11 element 70cm cheap yagi back up on the mast and my homebrew SaebrTrack and OR-360 AZ/EL TV rotator system interfaced to SatPC32. I have an ARR preamp mounted at the mast fed with a seperate 12VDC feed and about a 40 foot run of JEFA brand LMR 400. Once I get into the shack there is a bit of patchwork to the cables. I'm using a Yaesu VX3 to receive and due to the SMA connector on the HT and not wanting to strain it I have a 4 foot adapter cable of LMR 100 that goes from an SMA to a SO-239. I then have to use a short length of coax with a PL-259 to N male to mate up with a N barrel connector connected to my LMR 400 coming from outside. Now obviously, I know this isn't optimum and eats up valuable RF and I intend to change it ASAP but I'm hearing absolutely nothing on AO-51 passes. Not even the hint of signals. I'm thinking with that preamp in the line I should at lest hear something discernible besides noise regardless of the patchwork of cables. Am I off base in thinking this? I did catch just a bit of discernible signal off SO-50 last night but it was almost overhead. I'm not a beginner at this but I'm frustrated. Perhaps I'm putting too much faith in the preamp to push the signals through my hodgepodge of adapters and cables? Any thoughts are appreciated. 73, Michael, W4HIJ ___ Sent via amsat...@amsat.org.

[amsat-bb] Re: Frustration
Do you hear a noise increase when you power up the preamp? If not, are you sure you are getting power to it? Can you hear terrestrial repeaters, and does the signal change when you cycle the preamp power? Check your ins and outs on the preamp to make sure they didn't get reversed. Same thing for any diplexer you may be using as a high pass filter. More of the obvious...sure you are tracking correctly, and at the right time? I wouldn't suspect any of the cabling or adapters other than one being flat out broken. The preamp should easily overcome any shortcomings of the cable you've described. 73, Drew KO4MA ___ Sent via amsat...@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?

I bet a couple of hours with a volt-ohmmeter will find the guilty party. Alternatively, you could be in a bad noise situation. By way of comparison, because of my digital project right now I have a very minimal station, with a 70cm vertical antenna soldered directly onto a N-connector. About 10' of LMR400 goes to the preamp, which then has another 100' of cable to my FT-817. AO-51 is not great copy, but I know it is there. Similarly, all the usual cubesats in CW mode, and SEEDS (CO-66) with its fine FM signal of cheering Japanese school-children. (Actually, this got me thinking that SEEDS would make a pretty good way of evaluating two side-by-side receiving systems. Pass the resulting wav files through a SSTV decoder, and the one with the better picture wins!) You might consider making a very simple vertical antenna, attaching it to one end of the preamp with a very small patch cord between it and the radio, and using that as a kind of baseline. 73, Bruce -- http://ve9qrp.blogspot.com ___ Sent via amsat...@amsat.org.

[amsat-bb] Re: Frustration
I concur with what Drew states here. I am presently using (not by choice) a minimum setup with a 1/4 wave 2 meter homebrew groundplane for 70cm reception. I have an in-shack pre-amp that I use when I get serious in working AO-71 but I hear it rather well above 20 degrees without the preamp. I am limited to about 20 degrees or higher due to using the ground plane and a Ringo Ranger II for the two meter up link. Above 20 degrees the ground plan works well but the Ringo begins to lose signal due to radiation angle. I recommend following Drew's suggestion and also insure that your array is pointed correctly. An 11 element array can be narrow enough to easily null out the signal if you are not in the 15 - 20 degrees beam width.

[amsat-bb] Re: Frustration
Andrew, I definitely can heart an increase in noise when I power up the preamp and also see an S-meter response. Unfortunately I have absolutely no terrestrial repeaters within my range on 70cm. I've never been able to get into one even back in the days when I had my TS-2000X. Never been able to hear them either. Checked the preamp cables to make sure they weren't backwards also. In reference to some questions from others I've had, I am compensating for doppler on receive and I've checked all my cables except for the 40 foot piece of LMR 400 for open or short with an ohmmeter. Just for giggles I decided to see if I could copy NOAA weather on 162 Mhz band and I can. Don't know if that means anything. I will check my antenna pointing. Getting an accurate fix on true north has sort of been my achilles heel before but I've managed.There is not that much declination here. When I did happen to pick up the brief SO-50 transmission last night the rotator was making a fairly large change in Azimuth though. I may just whip up a quick little groundplane to give me a baseline as someone suggested also. Thanks for all the responses I've gotten so far.

[amsat-bb] Auto-Tune
I have been having a debate with my son about the overuse of Auto-Tune in music. Personally, I find it irritating. Then it occurred to me that I had proposed on this BB a long time ago that it would be nifty to have a DSP (Like Timewave DSP-599) that would correct for doppler. Has anyone tried Auto-Tune to correct doppler on a linear transponder? -- Joe Leikhim K4SAT The RFI-EMI-GUY© Use only Genuine Interocitor Parts Tom Servo ;-P ___ Sent via amsat...@amsat.org.

On my PCR 1000 i correct the doppler on my 2.4 GHZ downconverter IF with the AFC frequency tuning. It is effective but signal should be always present it loose track in the signal fades but easily corrected manually. Never tested yet on a SSB or CW signal only on FM. - Luc Leblanc VE2DWE Skype VE2DWE www.qsl.net/ve2dwe DSTAR urcall VE2DWE WAC BASIC CW PHONE SATELLITE ___ Sent via amsat...@amsat.org.
