[Elecraft] KX3, APF problem ?

[paul hippenmeyer]

Hi,

My little KX3 works great !

Just noticed following:
:
* MODE: CW
* CW bandwidth 50Hz
* CW sig properly tunend in with CWT and SPOT
* if CWT is ON: APF works perfect

* then CWT OFF
* when APF is turned ON, then received signal is significantly 
attenuated, why that ??
* CW sig is still properly on zero beat !!
* i can see this with bandwidths 100Hz or 50Hz only.


firmware CPU 1.27, DSP 0.99
