[Elecraft] KX1 Kit -- VFO Tuning and Readout ??

[Phil Hystad]

On page 64, left column (Pushbutton Switch Function), in the middle of the page on the description of the BAND button (single tap).  The text reads:

     [BAND]      One tap shows frequency (MHz first, then kHz;     L
                      or U is added in LSB or USB modes).  Two quick taps
                      selects the next higher band.


I think it should read as follows to make it more clear:

     [BAND]      One tap shows frequency: first MHz, second KHz, third display frequency
                      with resolution dependent on setting by VFO tap (or double-tap).
                      ...and so on...

What threw me for a loop was that the third display looked to be something unusual
since I was not expecting it and I was confused as a result.  I now understand how this
works but when first confronted by the display of MHz, KHz, and so on I was not 
expecting three different numbers.
