Magnetic North vs True North/ARISSat-1
by Carl Rimmer W8KRF 07 Sep '11

07 Sep '11

Thanks to all who responded. I was doing the right thing. Another dilemma was whether to orient the antenna to True North and not make any corrections in software or set it to Magnetic North and do the declination adjustment with the rotor software. Six of one, half dozen of the other. Right now I have it oriented to True North. But, like Pete said: For the work we do, a few degrees off one way or the other will not stop the show. BTW, I have noticed somewhat of a deterioration in the signal strength of ARISSat-1. I have not been able to copy any of the telemetry for the past several passes. I have copied a few of the SSTV pix and FM Voice, but even they seem noisier. Doesn't help that I have a power substation a few blocks away that obviously needs to have some of the insulators replaced. I called the power company and asked that they check things out. We'll see if they respond. Keep em flyin' *Carl W8KRF*

EM35 this weekend
by Rick - WA4NVM 07 Sep '11

07 Sep '11

Hi All, I will make my annual trip to Mt. Nebo, AR for the Sept VHF contest. I will use our contest call NE5BO from Thursday afternoon (9-8-2011) until Monday morning (9-12-2011) If you work me and need a card from EM35, just send me an email with the information, and I will send you a QSL next week. Also, there will be other operators in our group using their own call. So, there's no reason you can't mark that grid off your list. Also, Frank K4FEG will be on another mountain top operating from EM24. FM birds only. Good luck, Rick WA4NVM

Going to Elko this weekend and plan on hitting all the grids along I-80. I will bring all my brothers equipment so it should be alot better than when I went to So Cal. I will be taking pictures of GPS cooridinates and radio/antenna setup at each stop. I think that makes it official??? Will post more info tonight and am open to any suggestions. Thanks also to all the recent ISS Digi contacts been fun! Kevin KF7MYK

Attending the ARRL SW Div Convention Saturday?
by Clint Bradford 07 Sep '11

07 Sep '11

If you are attending the ARRL SW Division Convention in Torrance this Saturday ... AND if you've been thinking of purchasing either an Elk 2M/440L5 Log Periodic, an Arrow 146/437-10WBP, or Premier AL-800 ... Then have I got a couple deals for you! In conjunction with Ham Radio Outlet - Anaheim, mention "K6LCS Sat Special" at the HRO booth at the show, and get a couple bucks off the show price on the AL-800 and/or the Arrow ... and an impressive price of $82.95 for the Elk! AND THERE'S MORE! Bring your receipt from the purchase of a Yaesu FT-60R that you purchased from the fine folks at the HRO booth on Saturday to me - and the first four who do so will be handed a Smiley 270A antenna! I will be at the show from 7:30AM to dinner time on Saturday. Find me working the sats from the parking structure at the times posted all over the event. Or see me right before, during, or after my satellite show in Suites 9-11 which begins at Noon. Go ahead and interrupt the session - I only have FOUR of these great antennas to give away!

For the S band at 2400 MHz and a 1.2 meter dish to calibrate the Azimuth and Elevation I use the Sun Noise but the rotators have negligible backlash and the position readout can estimate +/- 0.25° Best 73" de i8CVS Domenico

ISS digi activity

Seems to be a lot more QSO's going on any more. I guess we can blame KF7MYK for some of his posts months ago, thanks Kevin. I did get QSL cards from Brad, N5LUL and Josh W9HT, and had a lot of packet QSO's in the past couple months through the ISS including a couple with Kevin, it has been fun -- AB9RU
