My KX1 has 30m and the ATU. Works way more than great, if there is such a term.. We're signed up for a trip thru the Canal in the spring (reason #1 for the KX1), and I have acquired what I think is a homebrew version of the MP-1 or sort of. N6QYS loaned me his real MP-1, and it looks pretty much the same and works (electrically) the same.
I've been using my MFJ-259B to pre-tune the antenna (with the goal of having the inductor settings marked so I don't have to take the 259 and try to explain that at the security checkpoint in the airports!), and then count on the KX1 tuner to handle the rest. So far, on 40m and 30m seem to come out OK. On 20, with the pre-sets I've been using, the best I can get is about 3:1 according to the KX1 after the ATU relays quit. Questions: 1. Any ideas on what is an "acceptable" (in terms of actually being able to work someone) SWR for the KX1? 2. As with all antennas, I can tune the antenna for a variety of resistances and reactances. I've been shooting for an impedance magnitude of around 50 ohms. Possibly some combination of R and X is more optimum? It's getting a bit chilly here in N. Cal. to spend time on the deck using trial and error (MN folks get one, and only one, joke apiece regarding "chilly") and I was hoping for some accumulated knowlege that will save me from the cold. 73, Fred K6DGW Auburn CA CM98lw _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
