My apologies to Joe (K9SZH) and to the AMSAT-BB. I should have sent my message directly to him and not through the BB. The ham mind works incorrectly sometimes, and I fell right into a wrong decision. Mike (K9QHO)

WD9EWK at Prescott (AZ) hamfest on Saturday, 30 May
by Patrick STODDARD (WD9EWK/VA7EWK) 28 May '09

28 May '09

Hi! On Saturday, 30 May 2009, I will have an AMSAT table at the hamfest in Prescott, Arizona. This hamfest is a joint venture between the Yavapai Amateur Radio Club and Verde Valley Amateur Radio Association, and will be held at the Granite Mountain Middle School in Prescott (grid DM34sn). The hamfest runs from 0800 to 1300 local (1500-2000 UTC). More information about the hamfest is available at: http://www.w7yrc.org/ham_fest.htm During the hamfest and before it officially opens, I will have demonstrations on FM satellite passes as well as VO-52. You may hear me on as early as 1300 UTC, even if I have nobody listening to the pass at my station except for me. After the hamfest, as I have typically done in the past year or so, I will make a long drive back home. I hope to make it as far north as grid DM36 for the AO-51 passes Saturday evening (somewhere on the south rim of the Grand Canyon, inside Grand Canyon National Park), and may be on AO-27 and/or SO-50 from grids DM34 and/or DM35 after the hamfest on my way toward grid DM36. If you work WD9EWK on Saturday, either from the Prescott Hamfest or from some other location later in the day, I will be happy to send you a QSL card (or cards) to confirm the contact(s). Please e-mail me directly the details for each QSO, and - if you're in the log - I will mail you the card(s). No need to send me QSLs or SASEs for my activity on Saturday. 73!

Re: M2 Xyagi sat 2 meter antenna
by MM 28 May '09

Hi Norman: I used KLM with a polarity switch many years ago. The polarity switch seemed unreliable and lossy, and I often forgot to change polarity on Leo’s. When I replaced my KLM with M2, I decided not to bother with switching polarity and just run RHCP. The benefits: No switch losses, more gain. Do not need to worry about forgetting to hit the polarity switch. Transmitter power not limted to switch. Other Tips: Go with the most elements you can afford for a single boom. 20+ elements on 2-meters 40+ elements on 440 Coax: You can now get Flexible thick coax that will support an antenna Rotor. Most people used RG-8 style coax, which is approximately 10 mm in diameter. However you can now get flexible rotor grade coax which is approximately 15 mm in diameter, and has much lower loss than the best RG-8 style coax. Example: Belden RG-213 145 MHz 2.5 dB loss per 100 feet 438 MHz 4.5 dB loss per 100 feet LMR 600 UltraFlex Rotor cable 145 MHz 1.1 dB loss per 100 feet 438 MHz 2.0 dB loss per 100 feet As you can see, by switching from 10mm coax to 15mm coax you can reduce you loss by over 50%. The 15mm cables cost 2-3 times as much, however you will not have to worry about coax losses any more on Frequencies below 2 gig. 73 wf1f --- On Wed, 5/27/09, Norman W Osborne <ve3cje(a)gmail.com> wrote: > From: Norman W Osborne <ve3cje(a)gmail.com> > Subject: [amsat-bb] M2 Xyagi sat 2 meter antenna > To: "amsat-bb" <AMSAT-BB(a)amsat.org> > Date: Wednesday, May 27, 2009, 1:41 PM > Hi Everyone, > Anyone out there using m2 Xyagi sat antenna with > switching? > Would like to hear your comments. > > I have settled on the gulf alpha for 70cm but I am looking > for more gain > for 2 meters. > > 73, > Norman. > _______________________________________________ > Sent via AMSAT-BB(a)amsat.org. > Opinions expressed are those of the author. > Not an AMSAT-NA member?

For about $65, I was able to build a modified version of the K8DAV U-100 Rotor controller, and now my Elk antenna turns automatically and follows the satellites during each pass. My particular rotor is the Alliance HIR, which is electrically the same as the U-83 and the U-98, and which I bought for $25. The K8DAV controller for these rotors is the same as the one for the U-100, except for the value of the motor start capacitor. The U-110 takes the same capacitor as the U-100. This was a fun weekend project and a very useful addition to my satellite setup. I picked up two of the most expensive parts, the transfomers, for $1 each at the Goodwill store, in the basket of assorted wall-warts in the electronics section (bring a VOM and test the wall-wart before purchasing). You could also use the transformer and capacitor from the rotor's original controller, but I was afraid to cannibalize it without being sure I could get the new one to work. Otherwise, the project box was $18, the Basic Stamp board was about $20, and the solid state relays were $7 each on eBay. All other parts were inexpensive.

Note that the interval is the frequency change, not a time interval. There are 2 separate tuning interval options you can select: one for SSB/CW signals, and one for FM signals. Typically, a tuning interval of 100Hz is fine for CW and SSB signals, while the FM interval should be set according to the capabilities of your radio and the actual mode of operation. 600 Hz should be fine for FM voice, while a smaller interval might be desireable for packet. Regardless of the interval you choose, updates will happen faster near the center of a pass....

Ciaran obtained his full license in April 2008 and enjoyed organising a very successful ARISS contact between Budbrooke School in Warwick, England and Richard Garriott K5KWQ whilst he was onboard the International Space Station in October 2008. The AMSAT-UK shop has been an important source of funds in the past and Ciaran is revamping the current shop to help it to continue to make a valuable contribution to the funds into the future. The shop has had a policy of only stocking items that are difficult to obtain in the UK and, initially, that policy will remain whilst Ciaran gets familiar with the stock and identifies other possible options. Suggestions are always welcome and a new email address (amsat-uk-shop(a)amsat.org) has been setup. Please send the suggestions in and keep checking the web site for updates. Due to the level of sales of software, and compatibility issues with the more recent Microsoft Operating Systems, it has been decided to stop selling InstantTrack and QuickTrack. WiSP and SatPC32 licenses will continue to be issued from the shop Also, there are currently no books for sale - we are looking at this but suggestions are always welcome. On the hardware front, we have restocked with the ever popular LVB motherboards and we also have a limited number of complete kits for the LVB Tracker unit. Half of the new kits also include the AMSAT-NA enclosure with compatible display unit! We are also investigating restocking the 2.4GHz signal sources from G0MRF and the G7HIA 2.4GHz patch kits - please keep a watch on the website for more details. The AMSAT UK website can be accessed via http://www.uk.amsat.org/ - the shop is accessed via a link on the left hand side of the web page. 73 Ciaran M0XTD ------------------------------ Message: 11 Date: Wed, 27 May 2009 18:29:03 +0000 (UTC) From: w7lrd(a)comcast.net Subject: [amsat-bb] IC-1271A available To: amsat-bb(a)amsat.org Message-ID: <3906341.5813511243448943652.JavaMail.root(a)sz0126a.emeryville.ca.mail.comcas t.net> Content-Type: text/plain; charset=utf-8 Hello I "may" have my IC-1271A all mode 1.2Ghz, 10W transceiver, with ATV module, and built in? power supply for sale.?

Piexx (who makes the IC-271 and -471 control boards) has made one for the 1271 now based on my radio which is there to figure it out. So if you want to do 1.2ghz with computer control, I would contact Bob and then Piexx.

10GHZ preparation
by Luc Leblanc 27 May '09

27 May '09

In view of what's is planned for the next P3E HEO i want to try some 10ghz band experiment I got a local Hamfest a Hughes LNA P/N 1011836-0009 personal earth station. My first google search does not give any results nor a direct call to Hughes company who even give less results... This LNA has a N type connector on it marked IF a F connector marked LNC another F marked POINTING and on the side another F connector on probably the LNA model PLV-810A. There is a rotary adjustable ring for vertical or horizonthal polarisation and a hand writing note "10-15GHZ KU" the TX power is 1Watt. If someone is aware ot the use of this PES or know where to get some manual it will help me to see if i can put this on the air? You can see a similar unit on e-bay at http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&ssPageName=STRK:MEWAX:VRI&ite… Thank's "-" Luc Leblanc VE2DWE Skype VE2DWE www.qsl.net/ve2dwe WAC BASIC CW PHONE SATELLITE
