K3 FSK D low tones?

[alsopb]

2KHz is getting a bit above my hearing range.

I wonder if there is a way to do low tone FSK-D @1275 Hz mark.
Not interested in AFSK.

I suppose the center frequency of the filter would have to be reset as
well as the dual tone filter.

Hi Brian,
Sure -- All you have to do is be in FSK-D mode, press & hold the SPOT (pitch) button.  Use the main tuning knob to set the mark tone you want and exit out of it.  Works just fine and all the standard tones are available in the menu.

I just checked it to make sure it works.

Thanks to Jim, W0EB.

It's already in there.

Just change the pitch while in the FSK-D mode.

In N1MM, if you're using a DXP38 modem, it is simple to change the mark
setting to match.

Works!  Now the audio signals are not attenuated by many dB.
