Hi Bruce, I printed packets from GO-32 on 23:59 UTC 29 Oct 2009, but haven't listened for it since then. Have you been listening to it the last few weeks? Perhaps it is down again? 73, Mark N8MH ___________ GO-32 Status ? -------------------------------------------------------------------------------- Subject: [amsat-bb] GO-32 Status ?

Yaesu radios
by Jean-François Ménard 31 Oct '09

31 Oct '09

Hi, I bought in a hamfest in Quebec, at a very very cheap price, two radio from Yaesu FT-726R and FT-736R. The FT-736R seems to be very neat. It is already connected and working with a CAT cable for satellite operation and finally replaced my 2 FT-817ND. Now I found that I finally have a real full duplex station, and I have a little more power. The FT-726R have the 144, 430 & 440 board in it. It is working very well too, but seems not able to control from CAT. Is there something I could do with this radio or this one is really too old to be part of a sat setup ?? Thanks & 73 -- Jean-François Ménard VA2SS =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= AMSAT www.amsat.org / Member #37102 ARRL www.arrl.org =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

Re: Simple 2.4Ghz helix plans?

http://www.csgnetwork.com/antennahtcalc.html http://www.rac.ca/tca/2006-01%20Helix%20Design%20Calculator.html Hello Mike Here are a couple I have used. Also find attached are a few pictures of past and some present antennas. I have followed the same process and building methods for L band antennas. I have used Drake, Transystem, Keps and SSB downconverters. The helix is pretty forgiving in measurements. I have the book "Antennas" by Kraus and have "tried" to follow the math and theory. Sort of fair in that regard. I find once I have built few and actually used them, I start to get a feel for them. Which downconverter do you have? There are several good articles in past AMSAT journals. Specifically by Clair-VE3NPC, also K0VTY -Joe, he has forgotten more than I'LL ever know. I have corresponded with them many times. I have built many short helix feeds (5 turns) for off center dishes. In fact that's what I used for AO-40 (sobsob). So, good luck with your efforts. If I can give you any hints, suggestions or whatever, just drop me a email. 73 Bob W7LRD Seattle ----- Original Message ----- From: "Michael Tondee" <mat_62(a)netcommander.com> To: "Amsat BB" <amsat-bb(a)amsat.org> Sent: Friday, October 30, 2009 9:03:02 PM GMT -08:00 US/Canada Pacific Subject: [amsat-bb] Simple 2.4Ghz helix plans? I threw this out there on the eham satellite forum looking for answers but I'll try here too. I'm looking for some fairly simple plans for this antenna. Everything I find either seems to be intended for WiFi or if it is ham related is full of mathematical formulas to figure length, diameter, spacing etc. Math was never my strong suit so I'd prefer to find something with the actual already computed dimensions clearly stated. Preferably in English rather than metric measurements. I found an article in the May/June 2008 AMSAT Journal that looked promising but there are no hard numbers, just the formulas and I don't have a calculator capable of some of the computations, much less being able to work them out in my head. Been a long time since I was in school!.. hi hi... I have a downconverter I'm not sure even works and I don't want to spend a huge amount of time and trouble to be able to test it. Tnx and 73, Michael, W4HIJ _______________________________________________ Sent via AMSAT-BB(a)amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?

Yaesu G-5500 azimuth and elevation resistor pots
by Mark L. Hammond 30 Oct '09

30 Oct '09

Hello All, We really need a FAQ section on the AMSAT web page for the Yaesu az/el units :) Anyhow, here's my question: Are the G-5500 azimuth and elevation resistor pots the same or different? Does anybody have the replacement part(s) number (s) handy--either from Vertex/Yaesu or another supplier? My azimuth pot is going bad. Thanks, -- Mark L. Hammond [N8MH]

Re: Yaesu G 5400 elevation rotator quit working
by Henk, PA3GUO 30 Oct '09

Hi John, To complement the description of Domenico, here is how my KR500 looked like from inside (picture 5&6): http://www.pa3guo.com/kr500.html I did clean it & apply greece over the balls. A photo of that greece (the brand) you get when you go to http://www.pa3guo.com and click on Rotors, then scroll down. Not sure if my problem was your problem. What you describe is different, mine was simply stuck. Anyway, all these rotors need some treatment :-) Mine worked fine since then (6 years now). Succes, Henk, PA3GUO

AO-51 mode VS success at 5 degrees
by Greg D. 29 Oct '09

29 Oct '09

Hi Drew, If you're still interested in mode VS signal reports, I just worked KG6NUB at 5 degrees elevation. He was pretty much full quieting on the 2.4 ghz downlink here in CM98, and reports he was using an arrow antenna with his HT out on the lawn in CM87 on his end (presumably running mode VU). Nice job, both of you! Greg KO6TH _________________________________________________________________ New Windows 7: Find the right PC for you.

Yaesu G 5400 elevation rotator quit working
by John 29 Oct '09

29 Oct '09

My Yaesu G 5400 Elevation rotator decided to quit working Friday morning. I could press the up and down buttons and hear the motor running but the antennas would not move. After being gone out of town for two days, I decided to try it again Sunday night. And to my amazement, it worked. The antenna moved. Anybody have any clues as to why this happens and what to do to fix it? Thanks, John C. KE5GFJ Pampa, Texas Ke5gfj(a)centramedia.net
