Special Event Station K4MIA NATIONAL POW/MIA RECOGNITION DAY September 15 -19 2010
National POW/MIA Recognition Day Ceremonies are held throughtout the Nation on the third Friday in September. The focus it to ensure that America remembers its responsibility to stand behind those who serve our nation and do everything possible to account for those who do not return.
This event was so successful last year it will now be an annual event. Many thanks to everyone that made it a success. If you worked me last year and would like the new style QSL please indicate on your QSL request. We are adding a second station and will also be on PSK at 14.070. SSB frequencies will be 14.265, 7.185, 3.885. If bands open up we will be on 28.415 and 21.285. See Sept QST or K4MIA QRZ for information. Copies of QSL cards on QRZ.com.
For QSL card please send your QSL and SASE to: MICHAEL N BALD 6758 Hall Blvd Loxahatchee, FL 33470
Thanks again for last years contacts and looking forward to this years very special event. 73 Mike K4MIA

Hi Guys, I have started my phased vertical project. The 1st vertical is in. I have a dumb question about installing radials. Can I attached both verticals to the same radial. If I tie both verticals together with some common radials (ground shield to ground shield) or over lap radials touching will this screwup my pattern, directivity or cause other problems.
Tnx 73 Mike

"By the way...do you have a wayu of MEASURING the phasing accurately? "
No Eric. Do you have a suggestions. Also, anyone out there know a NEC program that could model phasing of verticals. Hopefully a cheap or free one. Hi Hi
Thanks guys for all the reply's.
Mike

Hello WX7G Dave, Thanks for the reply and information. Sounds like the project is a go. I have a couple more questions. The phasing lines (approx lengths). If verticals are spaced 66 feet apart. Can one phase line be 33 feet the other 66 to be feed out of phase and the add 33 feet to make them in phase. Or do I need to start out 1/4 wave on 80 ( 66 feet) and add 66 more feet to make it out of phase? Second question, in the future can I also use this setup as a Cardioid array? I live in Florida. Currently I have a Carolina Windom and running a KW I get into Europe and South, Central America fine. But I need some help (gain) to improve the Pacific. Thats the reason for the additional antenna system. Mike

Hello, I am going to do my 1st attempt at phasing verticals. I have 2 Butternut HF2V verticals. I would like to have the phasing work on both bands. If I have them 66 feet apart can I phase them 1/4 wave on 80 meters and 1/2 wave on 40 meters. I know that it would be better phasing them on only one band. But could I do it without distorting the radiation patterns to bad. Get a good SWR in the phone DX windows and do without a tuner? Or if not, can it be setup for 80 and using tuner get good results on 40? I have done reading in ARRL Antenna Book, Low-Band DXing and Internet sights. But really could not find an answer.
Tnx and 73 Mike K4MIA
