Re: Turn off AGC when receiving BPSK-1000

> >You don't have to use a narrow beam antenna with maximum gain on axis. >You can always design it with a bowl-shaped pattern that increases gain >toward the edges and lowers it in the middle. That's why the quadrifilars work so well. I measured the pattern some time back, and the "beam width" is about 140 degrees.... Point them straight up and be satisfied with that part of a pass, or mount them at 40 degrees, and rotate AZ with a TV rotor for the entire pass. For 50 degree max passes point them at the center of the pass... 73, Dave, WB6LLO dguimon1(a)san.rr.com Disagree: I learn.... Pulling for P3E...

Kursk files bug in telemetry software?
by Roland Zurmely 19 Aug '11

19 Aug '11

It seems that there is a bug in telemetry software, perhaps created by the MET reset on each orbit? Each day, recorded files always have the same names: KURSK-944.1 KURSK-944.2 and so on... So I did the following: Every day end, I'm renaming the folder Kursk as kursk1, kursk2,... So I have a folder per day. Next day, when the software is launched, it creates automaticaly a new Kursk folder, that will contains the files from this day, with the same names of past days, but in a new folder. 73 de Roland.

Re: Frustrated -- not hearing ARRISat

Burns: Make sure your receive mode for frequency 145.950 is FM on your Kenwood F6A handheld. Before you upgraded with additional hardware could you receive ARISSat-1 signals using the stock antenna inside your shack? If you can, the next step is to remove the Diamond 2m/70cm duplexer as it might be blocking the amplified signal from your SSB 2m pre-amp. If that does not help, then it could be that the satellite signal are being degraded more than 75 percent or blocked entirely by the orient strand board (OSB) radiant barrier roof sheathing which is backed with a specially designed aluminum foil. The same goes if your dwelling exterior is fabricated with aluminum siding. It that is the case, then your only hope is to mount the antenna outside. 73's Mike Schaffer KA3JAW Tampa, Florida EL87

ARISSat-1 Transmissions over North America Thursday PM
by Gould Smith 19 Aug '11

19 Aug '11

During the 2320Z pass of ARISSat-1 over North America this evening a number of changes to the 2m FM transmissions were noted. 1) Male voice for telemetry means that the female voice files on the SD card could not be read 2) No greetings, mean that the greetings stored on the SD card could not be read. 4) MET of 2M while the satellite was still in a long period of sunlight - satellite must have reset during sunlight 4) FM transmissions consisted of voice ID, male telemetry and SSTV image in rotation Please send your BPSK telemetry into the server. 73, Gould, WA4SXM

AC0RA/m EN22/EN21
by Wyatt Dirks 19 Aug '11

Hi all, This Saturday the 20th of August I am planning on heading to the grid line of en22 and en21. I am going to try and be on all passes of SO-50, AO-51, AO-27, and FO29 between 1800z and 2200z. I don't know if I will be able to bring enough equipment to operate FO-29 yet. The main goal of my trip west is to help my sister move into her apartment for college so nothing is set in stone. If we make contact and you need a Qsl cards just sent me a email and the qso information and i will get a card to you as soon as possible. Also if anyone needs a qsl cards for my brief stay in en53 and when i was mobile in en42 just send me a email of the qso info and i will get a card out. 73 AC0RA Wyatt Dirks
