[Elecraft] KX3 - RMS Express USB Data Mode

[Darren Long]

Hi Keith,

I recently noticed something odd with my KX3.  I thought that the RX EQ
feature was inhibited in DATA-A mode, but it seems that it cannot be
adjusted but is still applied.  If I set the RX EQ in USB mode, I can
still see the adjusted response in DATA-A mode, but I cannot adjust it
in that mode.  Perhaps this could be related to your issue, Keith? Is
this normal?

Also, it seems that in DATA-A mode, the  audio drops off at about 400Hz
(with the PBT with of 4kHz centred on 1.5kHz), whereas in SSB mode, it
looks more like 200Hz.  I wonder why this is? I would prefer more bottom
end in DATA-A mode, I think.

Cheers,

Darren, G0HWW
