A few weekends ago (sweepstakes weekend) I broke out my KX1 in the
back yard to test and play with a few antennas I had been working on. (Tnx Mike, KK5F-Multi-Band Dipole) The ATU in the KX1 tuned the dipole beautifully with ~3.5-4 watts out. I then wanted to try the 24' piece of wire & counterpoise 12-16' combination as I haven't had any luck with this in the house or hotel rooms. The power out jumped up to 7 w as measured on my OHR WM-2 ! Knowing that's not possible, I'm befuddled. (is that a real word ?) I know I saw this discussed several months ago on the reflector, so I tried an archive search. I couldn't find this topic. Question: Does anyone remember this and what the reason(s) were? Or, could someone direct me to that subject in the archives please? One more question please. Does anyone have a link to a source were I might purchase a new MFJ-259 ant analyzer? I've been meaning to buy one for several years and just kept putting it off. I usually bookmark this sort of stuff when I come across it on this reflector, but darned if I can find this link that I also know has been beat to death on this reflector before. Tnx for the help !

John, isn't the OHR WM2 an in-line wattmeter?
If so, do you have it connected to your KX1 antenna jack and to a good dummy load? If your 24 foot wire antenna is connected to the WM2 it will *not* show the correct power. It requires a 50-ohm non-reactive load to read power accurately, and the 24 foot wire won't provide that. Remember, the ATU inside the KX1 does a good job of converting the impedance at the antenna jack to something close to 50 ohm non-reactive for the KX1 transmitter final, but it does nothing to change the SWR seen at the antenna jack. For the antenna analyzer, you might try MFJ at: http://tinyurl.com/3tgrr Ron AC7AC -----Original Message----- A few weekends ago (sweepstakes weekend) I broke out my KX1 in the back yard to test and play with a few antennas I had been working on.
