Foxtelem and FT-736R
by Tom Worthington 15 Oct '15

15 Oct '15

I've tried unsuccessfully to decode using the 9600 b output of my FT-857 into a sound card. The manual for Foxtelem refers to pulling the discriminator signal out of the Yaesu FT-736R for decoding. However, it does not suggest a point on the circuit. I'm thinking to try between Q20 and Q21 on the RX unit. perhaps a 0.1 uf cap to the collector of Q20? Has anybody else tried this? Thanks, Tom, NH6Y

Re: [amsat-bb] Eimac Moonbounce - I8CVS
by Thomas Doyle 14 Oct '15

Phil, Thanks for the post. Since I8CVS passed I had wanted to bring up a subject but was a bit hesitant. I8CVS had a mountain of information. He helped me with many things. It may seem a bit selfish but I regret that not only is he a SK but all that information is lost. It probably became a victim of the same 'paper eradication campaign' you described that will destroy your docs. Some info used to wind up on pages like this. http://www.amsat.org/amsat-new/tools/softwareArchive.php#win I hope the docs you shared wind up on some "permanent" web site. I am sure a recipe for gluten-free muffins or a youtube video of a cat wearing a dress dancing the polka would generate more interest than our old stuff from the old days but it would be a shame if it was lost. Must run - my garden full of kale needs tending, I have an appointment at the tattoo parlor and I need to pick up a new selfie stick to replace the one I wore out. tnx & 73 W9KE On Sun, Oct 11, 2015 at 6:14 AM, Phil Karn <karn(a)ka9q.net> wrote: > Way back in 1980 when I first got interested in amateur satellites and > AMSAT, I wrote off to Eimac Corporation for their "Moonbounce Notes" > collection. > > While on a household paper eradication campaign I came across them and > scanned them.

sat info database, SatNOGS
by Dan White 14 Oct '15

14 Oct '15

The SatNOGS project has a database component with a nice API for querying sat information. It is an active project, so it is far from a one-stop machine-queryable resource. But that is a stated goal of the component. https://db.satnogs.org (add "/api" to poke around what is query-able at the moment) I'll be at the Symposium this weekend along with a few of the SatNOGS people flying in from Athens, Greece, who will do a talk. IIRC they will be bringing some of the hardware also. In-person would be a great time for lots of discussions. As an open project, in practice things get done by someone doing it. Feature requests are nice, but a request accompanied by code is better. Everyone currently involved has a day job :) Let's work together! Dan White AD0CQ

AO-85
by W3MAT . 14 Oct '15

14 Oct '15

The other morning I attempted AO-85, listening to the down link on 145.980. I just sat down and listened to the recording of that pass. At the time I thought I was not making it into the sat, but upon listening to the recording I found that I indeed was making it, and at times quite strong. I was using the Arrow, two FT-60's, and headphones, but during the pass I could have sworn I was not making it, as I was not hearing myself...just squelch. I did learn from that pass though that AO-85 was much clearer on 145.975 in the latter stages, or after it passed the posted Max El for that pass. Just wondering if anyone else experienced the same scenario as I. I did tweak a few things with coax and radio programming last evening, and that seemed to make a noticeable improvement on the SO-50 (03:07Z) pass last evening. Have a great day everyone, Loon W3MAT

TLE's for AO-85
by Joe Fitzgerald 14 Oct '15

14 Oct '15

We are in that mad scramble after a cubesat deployment after a launch from a military mission where we don't have a good NORAD//JSpOC/ object number. People have been having good success with the object dubbed "GRACE_47" by CalPoly, with the placeholder number of 90747, and the TLE's have been added to nasabare.txt and nasa.all under that name and number. GRACE_47 1 90747U 15286.49403807 +.00001891 +00000-0 +21258-3 0 00074 2 90747 064.7778 276.6321 0217755 280.3643 225.3523 14.74250622000597 -Joe KM1P

AO-85 and Mr. Kepler
by Bob KD7YZ 14 Oct '15

14 Oct '15

I suppose I have the wrong Keps for AO-85 since I always seem 2 minutes too late for start and SatPC32 claims she's still below the horizon. Is it me, or should I find some secret set of TLE's for her ? -- 73, Bob KD7YZ www.qrz.com/db/kd7yz AmSat LM#901

AO-85 transponder 14-October, 0115 UTC
by Clayton W5PFG 14 Oct '15

14 Oct '15

Using the new GRACE_47 object (90747) for AO-85, I was able to make several contacts this evening using full computer control of my rig with SatPC32 v12.8c. SatPC32 tracked perfectly, keeping my rig on the appropriate uplink and downlink frequencies for AO-85. I worked a station while the satellite was at 2.2 degrees elevation over my horizon. My opinion is that Filter #2 works best for TX and RX with the Icom IC-9100 on AO-85. 73 Clayton W5PFG

Antenna Setup
by Rupert Hamblin 13 Oct '15

13 Oct '15

Hi AMSAT, I am looking for some guidance regards antenna setup for a fixed installation to work both FM sats & linear transponder satellites. My initial thought was: AZ / EL Rotator 2M xpol beam 5 ele ? 70cm xpol beam 9 ele ? LNA for both 2M & 70cm receive feeds ...plus some spare space on the boom, perhaps for 3 ele for LEO wx sats..? I appreciate this will probably cost a few $$ - but hopefully worth it....obviously won't build all this in one go..! Appreciate your thoughts / comments here..? Regards RH G0TKZ
