Hi Matt,
I agree completely.
Apart from reporting a (too much) "exact" JT65 frequency, a very minimal  
advantage of FC 1.28 is that you see the right  "band" and can narrow the  
filter ...provided the QSO is on the center of the JT65 waterfall.
(I was feeling alone, only on this topic  !)
Regards & 72 from FO land.

>> Here's the K3 OM's comment on the PITCH control:
>>
>> PITCH
>> CW sidetone PITCH,
>> PSK center pitch,
>> FSK / AFSK MARK tone and
>> shift (pg. 31), or FM tone setup (pg. 29)

>> For DATA A, the manual doesn't really state how to shift Fc.
