Drew - I had miles of RG-62/U in 1990s from data center conversions. After about 8 years of donations to various builders --- K5OE got my last 20 feet for the January / February 1999 AMSAT article on building the antenna! Greg w9gb Date: Sun, 30 Sep 2007 15:49:29 -0400 From: "Andrew Glasbrenner" <> Subject: [amsat-bb] Re: Large quantity of RG-62/U on eBay To: <amsat-bb(a)amsat.org> AMSAT - I have a 500 ft roll of "Wonderful" brand RG-62A/U in the garage that I picked up somewhere. For anyone that needs a piece, just send to my QRZ address an appropriate SASE and I will return a 10 ft piece of this coax for free. If so moved, you can include a donation to AMSAT or send one directly to Martha. I don't expect 50 requests, but when I get to 30 or so I'll warn everyone I'm running out. 73, Drew KO4MA

SUD (Small Ugly Dish)
by Eric H. Christensen 30 Sep '07

30 Sep '07

I just got back from a walk around the neighborhood with the wife (KI4IWS). For some reason she led us off our usual path and took us down a street we usually don't walk on. I noticed a hunk of metal on the side of the road and when we got close I noted it was a DirectTV dish being thrown out. Upon further inspection it was one of those newer ones with the three LMBs on board. Now to my 60cm dish... It is too small to support 1.2GHz because the 1.2GHz patch would block most of the dish and would prevent most of the signal from even entering the dish. Back to my "new" dish... Being that it is an offset dish, is 1.2GHz possible with this dish? Anyone tried this? 73s, Eric Christensen, W4OTN AMSAT Area Coordinator - Southeastern Virginia USA AMSAT Member 35360 http://www.ericsatcom.net Donate to the Eagle Fund - http://www.amsat-na.com/donation.php?donate=eagle

Keep It Simple Silly
by Patrick McGrane 30 Sep '07

30 Sep '07

Regarding Miles desire for simplified electronics, I wholeheartedly agree! I was very disappointed that amsat-na pushed for the SDX on the german P3E. I'm sure its a better receiver but its never flown. P3E was built around a proven AO-13 design. If someone were to fly a payload a quarter of a million miles to the moon, It should be dramatically simple and long lasting, That means no short life components like batteries. N2OEQ

I found a downconverter at a local hamfest. It has on the side, part number 2030/020 Camarillo, CA. Is this something I could use for mode S? Does not give a brand name on it. Thank You Dan N8DZM #33913

AMSAT members, and LEO satellite antenna builders: K5OE's article in the January / February 1999 issue of The AMSAT Journal shows RG-62/U used in the construction of the 'Texas Potato Masher' antenna for LEO satellites. Article can be found here: http://members.aol.com/k5oe/tpm.htm RG-62/U was used for many years as the physical media between IBM cluster controllers (3174/3274) and 3270 terminals. So this cable was very common is IBM data centers until past decade as mainframe access has moved from IBM's SNA to open standard LAN technologies. RG-62/U 93 ohm coaxial cable (95% braid coverage) being sold in 100 and 250 foot spools. TOM NURMI 15145 SE 180th STREET WEIRSDALE, FL 32195 eBay item number: 290164663358.

HI! Just got a brand new G-5500 and was wondering if it is possible to flip the meter scale to make it north centered as the old G-5600B? 73 de Sven LA6KJ No virus found in this outgoing message.
