[Elecraft] KAT3 tuning bandwidth

[Steef PA2A]

Guy,

I did another experiment: I tuned on 14.250, 1:1.2 is the result. On 14.240 the same tuning values are used and the SWR is still 1:1.2 From 14.239.999 downwards the SWR is 1:8.3 with other KAT3 parameters. Up to 14.299.999 the SWR remains 1:1.3 and from 14.300 it is 1:6.7.

It seems that old KAT3 parameters on other antenna 's are remembered forever. After using the K3 at the IOTA last week there has been much tuning and now all bands should be retuned.

I don 't like this at all. A new feature would then be to reset the old KAT3 settings or to 'calibrate' the whole band automatically with the KAT3. And after that it is a little step to a complete antenna analyzer feature on the K3 hi!

  If the feedline antenna combination is such that a 1.5:1 segment is
  only 20 kHz wide (a common enough occurrence) then one should take the
  time to get tunings up and down.  You can probably do it in a couple
  of minutes.  The K3 will shift seamlessly with your operating after
  that.  One of the benefits.
