[Elecraft] K2: HRD Power Control Anomaly

[Randy Moore]

I'm operating my K2/100 (KPA100+KAT100 in EC2) from Ham Radio Deluxe, 
which works just great.  But just now I was playing around with the HRD 
power control slider and discovered some anomalies. 

If I set the power on the K2 to say 50w, then move the HRD power slider 
down to < 11 w, the LCD power readout on the K2 follows the HRD slider 
down appropriately, but the KAT100 PWR RANGE LED stays in HIGH.  If I 
then transmit, the power is actually what I set it to (<11w).  So does 
that mean that I'm driving the KPA100 at QRP levels instead of using the 
K2 PA and bypassing the KPA100???  Moving the slider to other power 
levels (without moving the K2 power control) results in the same thing - 
power out follows the HRD slider, but the PWR RANGE LED stays at HIGH no 
matter if the power is set to <11w.

Now if I start with the K2 power control at <11w, first of all, HRD 
displays 10x the actual power setting (i.e., 100 for 10w).  That's easy 
to get used to.  But if I crank the HRD slider up beyond 10w (e.g., HRD 
slider to 150 or 15w), the actual power output, and the K2 LCD power 
display, go to 15w, but the KAT100 PWR RANGE LED stays in LOW.  Again 
does that mean that I'm driving the K2 PA to 15w and not going through 
the KPA100???

Is this a HRD "issue" or a K2 CAT command issue???

Kinda strange!
