[Elecraft] K2 setting KAT2 to bypass, display SWR

[Eric]

Don et al:

I am referring to the front panel leds on the k2.  My K2 is a QRP version with no KAT100.   I get the same indication with ATU CALS as i do with ATU CALP.  The KAT2 bridge must already be properly balanced since the X.X SWR display shows 1 with a KAT2 tuning operation on a dummy load.  Any ideas?  In the meantime ill redo the CALN procedure even though i'm sure the bridge is balanced

Eric,

Please clarify, There are no LEDs on the KAT2, but the external KAT100 does have LEDs. (The mind does get 'fuzzy' at 4 AM).

In any case, if you are talking about the KAT2, CAL S should show the SWR.  If it does not indicate SWR correctly, and the SWR changes with the power level, that is an indication that the bridge is not balanced - re-do the CAL n procedure to correct.

Pout shows forward power and reflected power.  In this setting, if the SWR is other than a perfect 1.0 match, there will be some reflected powr and it will vary with the power level.

I am trying to set my K2 to bypass the internal KAT2 tuner and display SWR.  When I set ATU CALS it shows the power out instead of SWR.  When I set ATU CALP I also get power out.  I am running the K2 into a dummy load through a wattmeter, wattmeter confirms SWR 1-1.  Even in ATU CALS the LEDs on the front panel vary up and down by the power out not the SWR.  WHAT AM I DOING WRONG?  WHY AM I STILL PLAYING WITH MY K2 AT 4AM?

thanks and 73
