Re: W6PAJ Orbit Calendar for Oscar 6 and or Oscar 7 (ca. 1972) 12 July 2009 To: Lurking Old Timers I need three consecutive pages and front matter from one of the W6PAJ orbit calendars published in early 1970's for a professional paper. (If you don't know what I'm referring to please just ignore this note). Scanned or Xerox copy via US mail is fine. Please reply direct, not via AMSAT-BB. Thanks! Martin Davidoff (K2ubc since 1956)

Antennas: How High?
by harry＠gunship.org 12 Jul '09

12 Jul '09

Guys, I want to upgrade from my hand held Arrow to something permanently mounted outside with and Ele/ Az rotor. I have a single story home with roof peak at about 22 feet. I can easily mount a 10' - 20' mast directly outside the shack anchored in concrete and bolted to my roof eaves. If I use two masts sections I will get a net height of about 17' which means I will be "looking" through my roof on the lower easterly orientated passes. Gaining the additional height to completely clear the roof line will be increasingly problematic. How much should I be concerned about this, etc? I'd like some real world feedback / suggestions. Thanks in advance. 73 de harry, W6DXO

For the past several weeks, I havent heard the 14.282 20m net on at 1900 utc. Last I heard when I talked to Larry W7LD more than a month ago, as he was net control. Is the net still active? Course with all the contest chatter, probably not be easy. John W6ZKH DM06

LVB
by WILLIAMS MICHAEL 11 Jul '09

11 Jul '09

I built my LVB up from the bare board which I ordered from G6LVB direct in the early days. It was a fun home brew project. Mine is bare bones. It has no display and no buttons. It just sits inside a Radio Shack box and does its thing day after day. If you look at my unit, the PCB just has enough of the components on it to do the job which it does well. I would highly recommend the LVB, it works well and is supported well.

I helped sell every one we had on hand at the AMSAT booth in Dayton. Another perspective, about 2 years ago I replaced my ISA bussed motherboard for a new one. The only ISA bussed mobo I could find(that was under $500) cost $190. Other then the two ISA slots, it had the comparable performance of a $35 mobo! My next computer upgrade for my sat control system will use an LVB to control rotors. The Kansas City tracker ISA card will be heading to the Smithsonian Institution.... 73 Jeff kb2m -----Original Message----- From: amsat-bb-bounces(a)amsat.org [mailto:amsat-bb-bounces@amsat.org] On Behalf Of Mark L.

Hi Myles, Simply stated---this is a very functional and easy to use track box, with exceptional attention to construction detail when purchased already assembled by AMSAT (thanks, Mike Young!). It's a very fair price at US$200. (Price out the parts to build one up...it's a deal). It's essentially plug in, calibrate, then play! I have (thanks to my long time elmer, Gene KC4SA) built a couple different homebrew tracking boxes since the late 1980's. The first used the parallel port to count "clicks" of the U100/U110 rotators. The latest incarnation uses a BASIC Stamp2 and G-5500. (I think a bit of research will show that our SAEBRTrack box was one of the first, if not the first, to make use of the PIC controller concept (built into the STAMP2) for a trackbox...). All of this is merely to say that I bring a reasonable perspective into the conversation... For the past several months, I have been using--by choice--the LVB Tracker! It's a great little box...currently using SatPC32 with the G-5500. In: summary--highly recommended! 73, Mark N8MH _________ LVB -------------------------------------------------------------------------------- Subject: [amsat-bb] LVB From: myles landstein <myles.landstein@xxxxxxxxx> Date: Sat, 11 Jul 2009 07:18:06 -0400 DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=gmail.com; s=gamma;h=domainkey-signature:received:received:message-id:from:to:in-reply-to:content-type:mime-version:subject:date:references:x-mailer; bh=9Q00jZSZs5nDFnnb8SPUQ/MZa1vD1IiGpeSvl/Hp1CM=;b=q3KMBfoKq24ExFzW0Xpp4w+6U5hI70CB4RCE5VucaywPahDjvMrW4O5Ha48/luRYeg+y+4GNS1GkNt6OEV9beDLcKzHakgsTb1J0PZbzC75Pi4IRsDc3mtlE6RvhTrjWVOWE8XYbaMBl9QhqTgwW1lYwnSRHzGzlhevf3Qgq5Lk= -------------------------------------------------------------------------------- Hi Just wondering if anyone out there using the LVB, could drop me a line and let me know their opinions and experience with it Thanks Going to Dayton '10 It will get better with more support!

Greg--contact me off-list and I'll try to help you with the PSK-1T (even though you apparently outbid me for these items, assuming you recently obtained them ;-) ) I've been using it to command AO-16... I don't know about the DFM unit, other than I think it is probably 1200 and 9600 baud capable. The PSK-1T can, as a stand alone unit, be used for 1200 baud PSK packet (like AO-16, IO-26, DO-64) and 1200 AFSK packet (like CalPoly-6). The DFM TNC doesn't need to be connected to the PSK-1T for it operate. If, however, you have a PSK-1 (without the "T"), it requires another TNC to be interfaced to it (like the DFM, an MFJ, etc.). My hunch is that the pair was used to add 9600 baud capability to somebody's satellite station... 73, Mark N8MH _______ John - That is the easy question. When Gywn Reedy, W1BEL (sk) and others set the specifications for the external contractor build of the PacComm PSK-1, they elected to use a common pin assignment/cable (late 1980s/early 1990s) for the 8-pin mini-DIN (rear panel of PSK-1) to the RS-232 (DB-9) on your computer. The cable for usage between an Apple computer and an Apple LaserWriter (serial port). I picked up a PacComm PSK-1 in May, replaced a blown capacitor on the 7805 regulator input and built this serial cable for connection to my personal computer's serial port. IF PacComm no longer sells this cable (you have to send an e-mail request to Linda), then any good Apple dealer or cable supplier should have this cable in their inventory for less than $25. Greg w9gb ==================== From: "johne tds.net" Subject: [amsat-bb] Paccomm information Hi I was wondering if some one has any manuals for the DFM TNC and the PSK-1 or the the PSK-1+? To get me going can some one please send the pin out for the radio 8 pin DIN for the DFM TNC. Thanks de John K0CQW -- Mark L.
