[Elecraft] K3 use with steppir antenna

W4GIW de W0XI,

I built a K3 kit with P3 last November (2014) and have been learning and 
enjoying. Prior to that I had (and still have) a Yeasu FT450D with YT450 
auto-tuner and SteppIR Vertical (33 foot max). Not sure if you are 
referring to a yagi-like stepper? Anyway, for now here's how I've been 
using the SteppIR vertical with the K3/P3 combo:

I have both the N3FJP and N1MM+ software and use both of them for 
different things with the K3. Most recently I've been using the N1MM+ 
for generic logging (using a modified contest log) so that I can 
record/change the frequency of the K3 from the keyboard and enter the 
call, RST and exchange if any. I have not, at this time, spent the time 
to figure out how to auto tune using the N1MM+ for the K3. For example, 
If I start out at 14025 on CW, I'll enter that into the SteppIR control 
box and then check the tuning with the ATU button on the K3. I seldom 
tune more than +- 25 kHz from 14025 (all CW) so don't seem to need to 
retune with the ATU button. I do watch the SWR display next to the 
transmit power indicator, bar graph. Then hit the ATU button if necessary.

I do like having the N1MM+ log the frequency of the QSO (and the time, 
etc), which it does, so I don't have to write anything down.

When time, I'll study how to merge the checking of the SWR with the 
N1MM+ and the K3 auto-wise; guessing that is possible.

So I guess you could say I'm half-automized! Hi. 73, Uncle Phil, W0XI, 
Lawrence, KS.
