Update 2017...I suppose an update here was way past due, but better late than never.  I would like to get more pics up though.  First and most important I no longer have antenna restrictions to deal with so I have been able to get a full size HF antenna up and now all the people who couldn't hear me very well can now.  The antenna is a horizontal loop that is about 535 feet long, a full wave for 160m; its fed with coax and a 4:1 balun.  It was up to 900 feet for a while and I would like to have it about 1000 feet long but there are logistical concerns to overcome for that so decided to go with the more manageable size keeping the shape more uniform and a greater percentage higher above ground.  Unfortunately it is still very low to ground, about 10 to 20 feet;  I ran the wire through available trees but its working ok. 

 

I have a lot of interest in portable and QRP operation so trying to find time to keep in practice with that.  The Yaesu 817 set up I use is great, small, only around 6 pounds for the whole package, battery and antenna included.  With the QRP amp it's 40 watts on 80m-10m.  Recently I got an Elecraft KX3 and use it in the shack most of the time.  I do have a 150 watt solid state amp to run with the KX3 and get more than QRP power.  For decent 2m operation I needed to put that antenna on the hill above me since I'm in a hole.  It takes almost 300 feet of feed line to get into the shack from up there.  For cost reasons I decided to use low lose 75 ohm satellite/cable TV cable I already had and phase two antennas to get a 50 ohm match.  I used a half wave vertical someone gave me and also made a full wave loop fed for horizontal polarization so it should be a dual polarity array.  I'm not sure that's a benefit so might have to try feeding the loop to have vertical polarization to see if it makes a difference.  I still need to get it higher of the ground too; it's on a pole only sticking 4 ft out of the ground so the bottom of the loop is less than a foot off the ground.  But it's working ok despite that and the feed line loss in such a long run for that frequency.  I wonder if using dual feed line helps reduce loss?  Guess you don't know how it works till you try.

 

Little about my radio life... first licensed in 2000, had some experience with CB radio growing up so got into using one in my 20's for 4x4'n and my interest grew so got into ham radio. In about 2006 due to "life" I put radio on the back burner till about 2011. I almost let my license expire, but renewed before the 2 year grace period was over. I upgraded to general ,and hoping to have time to keep enjoying the hobby and keep learning.
