[Elecraft] Internal K3 SWR vs Extermal SWR Meter

A better way is to connect a load with a known SWR.

Using a "BNC-BP BNC Male to Stackable Binding Posts" with three 100 Ohm
1W resistors in parallel, 33.3 Ohms, SWR should ~= 1.5.

Directly connected to the K3, ATU in bypass, 5W output, measured SWR = 1.1.

18" piece of coax with W1 Power meter, same 33.3 ohm load, K3 SWR=1.1,
W1 SWR=1.4 (Using W1 utility)

My K3 is indicating a Low SWR at 5W output.
