Ron -

I use RUMLog and cocoaModem on my Mac. RUMLog can use the RS-232 
interface to read the frequency from the K3. cocoaModem has been 
a workhorse for my on PSK-31 (90% of my operating time after FM 
repeater & SSB.)

My general PSK operating mode is to set the K3 to the base 
frequency for the PSK sub-band and lock the VFO (hold LOCK). 
When I start a QSO, I narrow the bandwidth of the radio to 
150-250 Hz using the Lo and Hi knobs. When I end the QSO, I have 
a macro to open the bandwidth to 2.3 KHz to fill my 2 KHz 
waterfall. I use the RF gain knob to control over-driving the 
Signalink interface. I use a Signalink because I have a MacBook 
Pro which can only do audio one way at a time.
