FW: [Elecraft] K1 KAT1 SWR Adjustment

[Strode, Carl R]

If the KAT1 merely tunes for the lowest voltage as developed at TP1, then does the KAT1 really use the <1.2:1 criteria to initiate an attempt at finding a good match?

Page #11 of the Rev. C KAT1 manual says:

"If the match is already very good (< 1.2:1), the tuner's L and C settings will not be changed."


Without adjustment of R2, how does the KAT1 know the difference between a good match and a bad match?

Of course, once the tuning process is started, the lowest voltage at TP-1 indicates the best match (assuming C9 was adjusted with a valid load).

Geez - my feeble brain is suffering from SWR overload.
