KAT100 problem, the sequel

[John Wiener]

I "hard reset" my K2 while trying to figure out why the KAT wasn't  
working properly.  I now know (thanks to Dave) that somehow the ATU  
switched from "auto" setting.

Now, I have to reset / recalibrate.  I re checked the 4MHz Osc  
calibration, the PLL Reference Oscillator Range, the VCO test,
Redid the BFO test and range.  All of these procedures were successful.

Redid CAL FIL and set all values to those in Table 8.2 on p 89 of the  
manual.
***I heard a carrier on LSB and some USB (?)***


I did not re-align the cans.
Did not re-do VFO Linearization

Now, my XFIL settings are off...audio freq changes substantially  
between X filters (but not between C filters)

My apologies for going over old ground, but what precisely did I mess  
up? :)

John,

A Master Reset wipes out any menu setting that you had established before
the reset, and the most crutial to operation is the CAL PLL and CAL FIL
values.

The Filter settings in the manual are OK as a starting point, but I recommed
using Spectrogram to refine the settings.  If you need information on how to
use Spectrogram to do the K2 dial calibration and filter setting, I can
refer you to my website (http://w3fpr.qrpradio.com) article on K2 Dial
Calibration.

73,
Don W3FPR
