Yes, I can set the HI CUT to 3Khz. Can it be increased to 6KHz to
match the AM roofing filter?
Not in AM mode. In AM there are two sidebands, so an audio frequency of
3 kHz results in upper and lower sidebands, thus requiring a 6 kHz filter.
In SSB mode, you can set HI CUT to a much higher frequency. The K3 can
pass audio with an upper limit around 5 kHz.
