[Flexradio] Manual notch filter?

[Ray Andrews]

Guy,

Of course, a notch filter could be coded to work anywhere in the range of 
the panadapter display.  However, don't hold your breath waiting for it to 
do what you want.  If the splatter is caused by an improperly adjusted 
transmitter somewhere else on the band, then the splatter consists of 
spurious signals that are within your desired pass band.  Notching out the 
main signal will NOT reduce the spurious signals -- they have already been 
put there by the dirty transmitter.

The only way that this type of notch filter would help is if the splatter is 
caused by overload in your receiver, either in the hardware or in the signal 
processing software.

Sorry,
