K3/SteppIR

[John's email]

I've had SteppIR antennas since 07. I have both a vertical and a beam. I run a K3 with KPA500 in the shack. I have no relays. When changing frequencies within a band the antennas are pretty fast. When changing bands, especially from say 80 to 10  or 40 -15 it can take several seconds for the antenna to adjust. I've never run into a situation where I thought I had to transmit faster than the antenna can adjust. I simply wait until the tuning led on the antenna controller goes out and then I can transmit. I'm not sure what could possibly be so urgent that I might have to transmit before the antenna stops adjusting. No danger to the K3 or the KPA500 by showing a tiny bit of patience.

Hi John, 111614

I just received my K3 kit  on Monday and am nearly finished with the
buildl; test is next.
I too have a SteppIR vertical and have been running it with my FT450D
and YT450D LDG autotuner.
They work well in combination - and as you say quick.

I will soon be at the point of crossing over to attaching the K3 with
internal 100 watt amp to the SteppIR.
Hence your note to the Elecract mailman list caught my eye.

I haven't read up yet on how automatic I can make that and how I might
interact with the KAT3 internal tuner option
I added to the K3. Don't anticipate any problems.

Unc Phil, W0XI, Lawrence, KS.
