[Elecraft] K3: SWR meter readings on 10m...

[VK7JB]

Hello All,

I've just noticed that the SWR meter on my K3 is reading higher than
expected on 10m.

I have 2 different 50 ohm dummy loads. Both have <1.1:1 as measured by my
external LP-100A meter and  my MFJ 259b AA.  

If I connect either dummy load directly into the ANT1 connector of the K3
(no connector lead at all or a very short lead between the DL and the K3
ANT1) and read SWR on 10m, it is measured by the K3 as 1.5:1.   On 15m, SWR
reads 1.4:1 but on 20m and lower bands, the SWR displayed by the K3 accords
with the LP-100A external meter (1.1:1).

Is this frequency-related phenomenon common to all K3's, or just mine?  Is
any adjustment possible or am I sweating over nothing.  Perhaps this SWR
difference is within spec @ 28MHz??
