[Elecraft] K3: Hi-Cut/Lo-Cut not available

[Tom H Childers]

It sounds like you may have the situation described below, from K3
Owner's Manual D10 Page 58.


 SIG RMV [T] NOR (Advanced) OPTIONAL SPURIOUS SIGNAL REMOVAL: Can  be
 used to remove fast-tuning receiver “birdies” that are audible  even
 with an antenna connected. (An alternative in SSB mode is to turn on
 auto-notch.)  Limitations: Applies  only to  CW/SSB/DATA modes,  and
 only to the main receiver. 

***** In CW and DATA modes, SIG RMV should  not be used in
combination with a CONFIG:PB CTRL setting of Shif t=.01.*****


 PB CTRL  Shift=.05  (Advanced)  Specifies  the  granularity  of the
 passband SHIFT control on a per mode basis: .05 (default) or .01
kHz.
 Select the desired mode first, then select the desired  granularity.

 *****Limitations: Only applies  to CW and  DATA modes. Selecting .01
kHz reduces  the  SHIFT  range  and disables  HI  CUT  and  LO CUT.
May interfere with spurious signal removal (CONFIG:SIG  RMV), i.e.
“removed” signals may not be shifted the right amount, and thus may
again be audible. *****
