more antenna discussions....
by zach hillerson 18 Mar '11

18 Mar '11

I'm still struggling to figure out the best antenna configuration for me. I was originally planning (and now own) to use a Gulf Alpha dual band fixed at 15* elevation, but I am now having 2nd thoughts. Being limited to 1 roof top tower it might be prudent to get as much use out of the single mast as possible. If I go with 2 horizontally polarized linear antennas on a cross boom(1 ea. 2m and 440) could I use them for both satellites and weak signal work? Is there a downside to proceeding this way? One concern that I have is that the horizontal antennas seem to have a somewhat limited frequency range, and I'm not sure of the impact. Also, is it prudent to go with separate azimuth and elevation rotators to allow for future expansion (6m etc...), although the separation required between booms is height prohibitive with 6m? Is anyone running a setup similar to this? Are you happy? Any thoughts, opinions etc... would be appreciated, Zach N4ERZ

Andrew I agree with you. I use a 17B2 and 18 ele M2 and have worked 50 states and VUCC+ but no elevation does causes me problems with birds above 18 degree elevation. A good 70cm preamp makes all the difference in hearing on the FM birds. It is best to have azel and elevation with cir pol, but not necessary.

For several years I've used a 2m7 or cushcraft 10 element horizontal yagi on 2m with fine results. Being horizontal allows me to play on terrestrial as well as meteor scatter where the extra gain from polarity makes a huge difference. Sat links are generally good enough that it doesn't matter much at least on 2m. Obviously there is some compromise in this setup, but it hasn't been a problem yet. 73, Drew KO4MA _______________________________________________ Sent via AMSAT-BB(a)amsat.org.

All, I would like to take this time to thank everyone for your patience with the EM40 QSL cards. About 250 cards went out with and without SASE in the last 3 days. If for any reason you do not receive a card for a contact with me, please email me ASAP the QSL information and I will make sure you get your cards ASAP. Once again, thanks everyone for your patience. Angelo Glorioso / N5UXT --------------------------------------------------------- If you don't ask, you will never know!!

Hamlib for Windows and COM ports question (re: Gpredict)
by Mark L. Hammond 18 Mar '11

18 Mar '11

To those who might know--- Does hamlib for Windows support more than just COM1 and COM2 for hardware (radios, trackboxes)? If so, what is the syntax? I've tried the obvious permutations based on the command line help and online help I could find...but it isn't working on COM5. It just "hangs" with no errors and it's obviously not working either. I am aware of the baud rate command line option, but that's not it...from what I've read it gives the impression (but isn't clearly stated) that it might not support above COM2. Surely that can be fixed (heh...not by me!) Gpredict for Windows is very nice and a super program, but if I can't use ports higher than COM2 because of hamlib, it's use in my shack is very limited... 73, -- Mark L. Hammond [N8MH]

In keeping up with technology and limiting duplication of work, AMSAT Awards will now accept a scanned copy the Radio Amateurs of Canada (RAC) CANADAWARD for satellites as proof of working the 13 valid Canadian Provinces. They are: VE1/VA1 Nova Scotia VE2/VA2 Quebec VE3/VA3 Ontario VE4/VA4 Manitoba VE5/VA5 Saskatchewan VE6/VA6 Alberta VE7/VA7 British Columbia VE8 Northwest Territories VE9 New Brunswick VO1/2 Newfoundland and Labrador VY0 Nanavut VY1 Yukon VY2 Prince Edward This will make it easier for everyone to submit either or both, ARRL Worked All States / RAC CANADAWARD and not have to scan all those cards and have me check them a second time. 73...bruce -- Bruce Paige, KK5DO AMSAT Director Contests and Awards ARRL Awards Manager (WAS, 5BWAS, VUCC), VE Houston AMSAT Net - Wed 0200z on Echolink - Conference *AMSAT* Also live streaming MP3 athttp://www.amsatnet.com Podcast athttp://www.amsatnet.com/podcast.xml or iTunes Latest satellite news on the ARRL Audio News http://www.arrl.org AMSAT on Twitterhttp://www.twitter.com/amsat
