[Elecraft] K3 with P4dragon DR-7800

[Johnny Siu]

Hello Gentleman,

In fact, I was annoyed by SCS modem.  I sent Martin of SCS modem emails and asked him about the connection between their modem and K3 or KX3.  SCS modem's answer was a simply 'no', no information available.  It was a very frustrated experience.  Perhaps, SCS modem is more interested in marine radio sector.

My original ideas was that KX3+ Pactor 3 or 4 modem will be a good combination for many communication purposes.

P-T,

If you follow the instructions frequently given on this reflector, you 
will have proper power control and no flat-topping.
For soundcard Data modes, monitor the audio input level on the ALC 
meter.  You should have 4 bars illuminated with the 5th bar flickering.
The first bars of the ALC meter do not actually indicate ALC - the onset 
of ALC is at the 5th bar, so the lower bars are used like a "VU-meter" 
to aid in adjusting the audio drive level.\

The closed loop method of power control used by the K3 requires that you 
fully drive the audio and use the power knob to set the desired power 
output.  Attempting to control the power with the audio drive will 
result in "power hunting".
