Uni-Track 2000 info
by Edward R Cole 02 Oct '15

02 Oct '15

I'm back on the amsat-bb. I need help finding info on a UniTrack-2000. I've had it since around 2000 but never installed it. Now there is no info on the internet, so hoping someone here might have a lead or have the manual. There is a link to the Uni-Track 2003: http://homepages.paradise.net.nz/lamontd/ but no help on the Uni-Track 2000. I have the unit and I/F cable for the Yaesu-B5400 az-el rotator. The cable has the proper 8-pin DIN to connect to the Yaesu and three other wires, one of which is power. The other two are two-wire shielded cables, one of which is marked ECP0=red and ECP1=blk. One issue is the Uni-Track uses a printer port I/F to a computer (DB-25), but computers are no longer made with printer ports. I wonder if there is a conversion cable to USB jack, or maybe a printer port card (PCI buss)? I just bought a replacement B5400 controller for the broken one I have, so I will be able to restore my satellite antenna system. B5400 rotator is in good shape. 73, Ed - KL7UW http://www.kl7uw.com "Kits made by KL7UW" Dubus Mag business: dubususa(a)gmail.com

Lilacsat 2 Over DO33
by B J 01 Oct '15

01 Oct '15

I worked 2 passes earlier today using my IC-910 and putting 5 W into my Arrow yagi. The first had a high elevation and I was able to reach the bird once it came from behind my building. The signal was good until about a minute after TCA when it became harder to hear. I don't think that was due to an adjacent tower in my apartment complex. The second one had a maximum elevation of about 10 degrees. I'm not sure I heard my downlink but, if I did, it was very weak and down in the noise, even though there were few obstructions. I noticed something similar during the pass I monitored early morning UTC yesterday (i. e., Tuesday evening local time). The signal varied in quality as the satellite approached the horizon close to LOS. 73s Bernhard VA6BMJ @ DO33FL

ARISS Contact - 6 October
by John Spasojevich 01 Oct '15

01 Oct '15

Please join us in listening to the ISS contact with participants at the Corpus Christi Catholic School, Chambersburg, Pennsylvania, USA Acquisition of Signal (AOS) is anticipated to be 16:29:32 UTC The duration of the contact is approximately 9 minutes and 30 seconds. The contact will be a telebridge between NA1SS and LU1CGB in Argentina. The contact is expected to be conducted in English. Audio from this contact will be fed into the: EchoLink *AMSAT* (101377) IRLP Node 9010 Discovery Reflector Streaming Audio at: https://sites.google.com/site/arissaudio/ Audio on Echolink & web stream is generally transmitted around 20 minutes prior to the contact taking place so that you can hear some of the preparation that occurs. IRLP will begin just prior to the ground station call to the ISS. Please note that due to control issues with Echolink and IRLP there are manual breaks approximately every 2 minutes to prevent timeout of connected repeaters and links. You may still time out depending on your local configuration. ** Contact times are approximate. If the ISS executes a re-boost or other maneuver, the AOS (Acquisition of Signal) time may alter by a few minutes **

Re: [amsat-bb] Mirage T-injector Problem
by Richard Lawn 01 Oct '15

01 Oct '15

Finally did diagnose the problem as a 2.5 volt drop under load at the T-injector. With the output on the bench showing barely 11v under load this brought the voltage down to the bottom end of what the ARR preamp needs to function. I suspect that under load at the end of 60' of coax it was even lower than 11v. Jay at ARR was very helpful in working with me to get to the bottom of the mystery as I had the same problem with two different vintage Mirage T-injectors and both worked fine with Mirage and Icom preamps, so it was quite a mystery. We determined that if you eliminate the 10ohm resister off the injector pwr switch and replace it with a jumper the problem is solved. Of course I could have used a separate line to remotely power the ARR preamps but that was going to be very difficult at my QTH. Problem it looks like is solved. And thanks to everyone for your useful suggestions and questions that led to solving the mystery. 73 Rick, W2JAZ

finally worked Lilacsat-2
by Perry Yantis 01 Oct '15

01 Oct '15

Finally this morning I made a LilacSat contact with WI9I on orbit 172 a few minutes ago. I found that switching to left handed circular polarization and turning the RIT to about 5 khz offset then I started hearing something. The elevation was about 20 degrees but the signal was still very noisy. Then I noticed that when the satellite got to a higher elevation I started to hear stronger signals from AA5PK. At this time the rec signal was better but then I could not get a signal into the bird. My guess is that as the keps get better that my antenna aiming will get better and then signals should be better. Just have to wait and see. Perry WB8OTH

Lilacsat 2 , orbit 165.
by PY5LF 30 Sep '15

30 Sep '15

Hi Here my a few minutes of Lilacsat 2 over Brazil , FM transponder . I would like to know about signal reception from other station , because I feel the signal very weak , audio quality excellent. May be my reception problem. https://youtu.be/ps_AgAyuBrA 73 PY5LF Luciano Fabricio Curitiba-PR-BR GG54jm http://www.qrz.com/db/PY5LF

First Crack at Lilac-Sat2
by Rick Tejera 30 Sep '15

30 Sep '15

All, Finally got off my duff and set up for the 0125UT pass of Lilacsat2. From DM33 it was pretty good western pass, max elevation of 58 degrees. The radio was reprogrammed with the new downlink frequencies (thanks Clayton, Ted & Patrick). Heard nothing did not hear myself on the downlink. used my TD72A, so i was putting up 5 watts. Now I've heard several stations say they can't get in with 5w and other that can, i suspect antenna gain may be a factor here. Now one thing I did notice is when i keyed up, i did hear an increase in the noise on the downlink. Wonder if that was my signal barely getting in or not? Did anyone hear me (K7TEJ)? If I have time Saturday, I may try taking the TS-2000 out and see if i get any better results Rick Tejera (K7TEJ) Saguaro Astronomy Club www.saguaroastro.org Thunderbird Radio Club www.w7tbc.org 623-572-0713 623-203-4121 (cell) SaguaroaAstro(a)cox.net
