Who was that, Purolator Courier? Ever since then, we, as a society cannot wait for anything. And when you tell people thay have to wait; or that they can't have it as soon as they want it - you're looked at like you have three heads. Want to see the definition of impatience?

I was hoping to hear you... I did work the K8LJ and heard about 3 or 4 stations calling at the same time but he was the squeakiest wheel so got my attention. Sure was strange the way the band would drop out suddenly! Be watching for you in the future! Want to hear that new rig soon! 72, Kelly K4UPG Shucks!

Tried working you on 20 Meters; but I think it was K8LJ that you ended up going back to. I tried again in a bit; but then the band collapsed and I didn't hear you again. Larry W2LJ Hey Kelly!

Further south they got LOTS of rain and even some local flooding, but we missed that. Guess you cannot have everything, eh? Last year the wx was OK and bands were zippo so I don't think I even submitted a log. That's a lot harder pill to swallow, isn't it. Didn't hear a VE call all day which is pretty unusual. 72, Kelly K4UPG Yes the wx was nice, a bit hot, but nice! Further south they got LOTS of rain and even some local flooding, but we missed that.

I too was out on Saturday with my K2 on the deck at home. The weather here was not that great I was not able to make any contacts due to a looming storm and poor band conditions.

I think I grasp what you are saying and makes a lot of sense to me. Do you have any write up or photos on the net to help me visualize it a bit better? Would love to see how you have done this in more detail... i.e. lengths for the bands and how you are connecting the capacitor and length of coax. When you say 2 element in series Magloop... are you speaking of two main loops or just the faraday inductor? Very thought provoking and my original loop has been mostly idle and most of my operation is on weekends when I have time to go out in the field portable. 72, Kelly K4UPG Myles,

Use the inner of RG-213 coax and slide it into one tube, this acts a a capacitor. By finding what length is required for a band you are set. I use 3 lengths, 20M 30M and 40M, you could also have anothe cap in the other tube end, and connect the two with a wire link. I am using a 2 element in series Magloop - this halves the cap needed to reach resonance. The Faraday induction loop is never adjusted. The varying cap tunes to loop. I also tape the ends on the coax inner to prevent arcing. Other caps can be made with PET as the dielectric material, soda bottles are made from PET, it will withstand 20KV. I realise this article is in 2009. I make 5 Watt contacts on WSPR at 18,600KM everyday. Use a Faraday induction loop, the SWR will be 1.1.

I have had a blast <em>listening to the mail</em> on w4ax.com site. It works pretty well and is in the general area of the SE US so gives me an idea how the bands might be locally. I've wondered if I could use it for a receiver and xmit with my Argonaut on some of the bands that I don't have modules for with my Sierra. Enjoy the site! Merry Christmas too! 72, Kelly K4UPG Always good to hear from you Mike! I have had a blast listening to the mail on w4ax.com site.
