"How does that help anything if the tuner bin width is 8 kHz? "

I had confused the rf frequency detect counter resolution with the bin width.

For KAT 500:

Below 3 MHz the segments are 10 kHz wide.
>From 3 MHz through 26 MHz the segments are 20 kHz wide.
>From 26 MHz to 38 MHz the segments are 100 kHz wide.
>From 38 MHz to 60 MHz the segments are 200 kHz wide.

For KPA1500:

160 Meters, 10 kHz Steps
80 Meters, 10 kHz Steps
60 Meters, 20 kHz Steps
40 Meters, 20 kHz Steps
30 Meters, 20 kHz Steps
20 Meters, 20 kHz Steps
17 Meters, 20 kHz Steps
15 Meters, 20 kHz Steps
12 Meters, 20 kHz Steps
10 Meters, 100 kHz Steps
6 Meters, 200 kHz Steps

Both data sets extracted from the user guides.  They seem to be similar but I 
have not checked every frequency range.

I still don't see the advantage of AUX bus giving the KPA1500 the TX frequency 
to 1 kHz resolution.   What am I missing?
