A mag loop needs to be retuned every time you change frequency. If you usually operate in one spot for a while, say a CW or digital subband, that is fine. If you tune around, you’ll want something else. You can’t even hear signals on other frequencies until you tune the mag loop.
If you can run a 26 foot wire, do that. Use a 16 or so foot wire on the ground as a counterpoise. Connect them to the KX3 with a double binding post adaptor and press ATU TUNE. Or you can use a railing-mounted whip, like this one. MFJ also makes a 12 foot whip which might fit this coil. With a short feedline, I’d probably bypass the coil and let the KX3 ATU do the work. https://www.mfjenterprises.com/Product.php?productid=MFJ-1622 wunder K6WRU Walter Underwood CM87wj http://observer.wunderwood.org/ (my blog) > On Jun 4, 2019, at 11:17 AM, Kevin, N4TT <kkinde...@gmail.com> wrote: > > I have had great luck with the simplest of end-fed antennas and the KX3. > Particularly out at the picnic table I can just find a convenient tree to > toss up one end with the other end at the table.
