kx1 antenna matching

Rick Dwight
Stan,
     Congratulations on getting your antenna working on all 3 bands.  The 25 ft radiator is a very good length for 30 and 20 meters and good enough for 40.  With the radiator vertical, sloped, or set up as an inverted L you should get many good QSO’s often from 600 miles to around 2000 miles, depending upon band and conditions.  QRP DX on 20 and 30 of well over 2000 miles will sometimes be possible, but often with poor signal reports.  However much of my fun has been rag chewing with stations on 40 meters lets say less than 600 miles away.  Sometimes I used the 25 ft sloped so it is partially horizontal and sometimes use an elevated 34 ft counterpoise wire which I throw over a tree branch, or even lay on top of bushes.  Operation from the UK, especially in the non summer months, often in the daytime, was very productive, especially from something like 200 miles to roughly 500 miles…..many long rag chews on 40 to the Netherlands, France, and occasionally to the opposite corner of the UK.  Sometimes late afternoon or nighttime conditions are OK also.  We are now in the low part of the sunspot cycle, so not sure how this will work.  DX on 20 with the radiator vertical (or mostly vertical) is not too hard to work, but QSO’s are often “RST 339, tnx QSO 73’s”.  Do consider half wave end fed antennas with a good matching device…many QRP folks really like them…I do not have much experience, but they have worked fine the few times I tried them.  A linked dipole is what I set up if I am going to be in a contest, or am operating for a long time, especially if there is a tree support for the center of the inverted V at least something like 25 feet high.  This will give you some good moderate angle radiation for good coverage out to say 1500 miles ROUGHLY on 40 and some real DX is possible on 20, especially when conditions are very good.
