[Elecraft] Audio Improvements on a K2

Hi

Yes you are right. Except the transmit circuits are not affected because =
the second Xfilter is switched out when transmitting. The 120 pf cap is s=
witched in when OPT1 is selected, but only matters on receive.

It is my understanding that removing C180 IS the filter flattening mod.  =
The 120 pf cap that is added is only switched
in when the OPT1 filter is selected (always for TX and when OPT1 is used =
for RX).  Right?
