AMSAT.org website - where to donate?
by John Mock KD6PAG 26 Nov '07

I want to make a small donation to AMSAT-NA (specifically for satellites which would accessible on a world-wide basis). But, alas, i could only information about membership and the "President's Club" on-line. Did i miss something?? It seems like it might be a missed opportunity not to have information on-line about making a one-time-only donation. -- KD6PAG (Networking Old-Timer, Satellite QRPer)

Is it also possible that humidity succeed to form inside by temperature variation and or by entering by the joingning sections. My model a Yaesu G-550 looks like the same as the Kenpro KR-500 and does not seems to have any drainage hole in the casing but this will have to be visually confirm. Looking at the exploded inside schematic picture of the rotor it seems that it is possible to drill a hole in the casing to drain this excess water? Could be someone who open one can confirm if there is enough clearance to avoid drilling through the gear/motor system? Thank's for all your advices and for all the private one too.

Re: Mast strength??
by Greg Beat 26 Nov '07

26 Nov '07

Charles Penninger (Penninger Radio) has that "in stock" in western Chicago suburbs (15 miles west of my QTH) You likely also have a local aluminum tubing supplier / distributor in your area -- without having to pay for the shipping charges. 1/8" wall is very nice -- and surprising lightweight for its strength. At the 2 inch diameter size you can use either 1/8" or 1/4" wall http://www.penninger.com/prod05.htm Greg w9gb Date: Thu, 22 Nov 2007 14:13:57 -0500 From: "Stargate" <stargatesg1(a)verizon.net> Subject: [amsat-bb] Mast strength?? To: "Amsat-Bb" <amsat-bb(a)amsat.org> Message-ID: <HLENIILIDNGDDDJIDEMFGEMGENAA.stargatesg1(a)verizon.net> Content-Type: text/plain; charset=iso-8859-1 Hi all, I am installing 20' of Rohn 45 with a flat top from Normsfab and a Yaesu GS-065 thrust bearing. The lower end of the tower is already figured out but I'm not sure of what strength 2" mast I need. All this short tower will be supporting is a 3-4 element 6M homebrew beam just above the bearing on the tower, as well as, the elevation portion of the Yaesu G-5500 rotor with 8' fiberglass cross mast, and M2 2MCP22, and 436CP42UG beams on each end of the cross boom. The 2MCP22 is 2.5 sq ft wind load. The 436CP42UG is 2.0 sq ft wind load. I'm not sure of the WL for the rotor and 6M beam. The mast will have to be at least 18'-20' long to give 2-3 foot inside the tower to the AZ rotor and enough sticking out the top to give 1/4 wavelength (at 2M) spacing between the satellite antenna's and the 6M beam. The satellite antenna's are close to 20' long and mount from close to the center so I need at least 10' (+1/4 wavelength) above the top of the 6M beam. I'm not an engineering type so I thought I would ask on here. What thickness and material would the mast need to be to support this. I am thinking T6061 aluminum, .25" thick wall, 2" outside diameter mast. I live in a 75mph wind zone. Any help would be much appreciated. Thanks, 73's RoD KD0XX

input about best CAT controlled duplex multi-mode satellite rigs
by Dr. Jay Garlitz 25 Nov '07

25 Nov '07

Input about best CAT controlled duplex multi-mode satellite rigs to Mike Baker, WA4HFR, at micanopymike(a)gmail.com would be appreciated: A couple of my local ham friends have finally convinced me to get geared up to work the ham birds. My interests lie more toward the higher frequencies, 2GHz and up, but I do plan to get started on 144 and 432 bands. My question: What are a couple of the very best or most recommended VHF/UHF station rigs for working the birds? Are there any VHF/UHF multi-band mobile rigs suitable for working the ham birds? I presume that suitable rigs must have software controlled doppler correction capability? Thanks-- Mike Baker WA4HFR Micanopy

rs-15 now eclipse again
by Auke de Jong, VE6PWN 25 Nov '07

25 Nov '07

It seems that by my observations that the beacon transmitter was reliable throughout this latest period of non-eclipse. I noticed that the beacon frequency was always the same(29.3512 usb), and the on/off timings seemed to indicate some state of information by slowly changing the on-duration, and keeping a steady off-duration. Now that the orbit has progressed away from the sun on the ascending node, I think it will be interesting to see if the unit will power-off and on for sunlight and behave in predictable ways or whatnot. There has been some reports from before the non-eclipse period started, where the same beacon signal was heard on a different frequency, but this was before i started listening. If anyone notices interesting behaviour such as different beacon frequencies of messages, or if they have information on how to decide what the beacon information might mean, I would be very interested to hear about it. Thank you Auke de Jong, VE6PWN DO33
