Dave,
Do you have the transmit audio levels set correctly? The ALC meter
should illuminate 4 bars during transmission with the 5th bar
flickering. If that is not the case, increase the audio drive level
(either soundcard settings or KX3 mic gain or both) until that condition
is met.

Hello again ELMERS,
(I appreciate all the help from the mail list, but I decided to standardize on
Fldigi and my Macbook Pro … because this is what I am most comfortable with … I
know there are other MAC HAM GURUS out there …)
I am trying to use Fldigi, a Macbook Pro, a Griffin iMic and my KX3 to talk
PSK-31. With the help of you folks here, I have the receiving/decoding part of
this process working. I am getting great decoding.
TRANSMITTING IS A FRUSTRATING DEAD-END.
My setup is cabled as follows:
ACC1 to the KX3SER Port connected. The KX3 Utility reports "usbserial-AD02DUIQ"
at 4800 bps. Why I need this cable setup is beyond me, can someone explain the need?
My iMic is connected to the Macbook via USB port. The iMic switch is set to 'Mic". The headphones
from the KX3 go to the "In" port and the KX3 Mic is connected to the "Out" port on
the iMic.
The Macbook Input and Output levels for the iMic USB audio system are at 1/2
level.
Playing with the ALC control, the Keyer/Mic is set to 3-4 level and the AF is
set to 20. A nice waterfall appears and PKS-31 is decoded nicely.
Under Rig Control, I have experimented with both RigCat and hamlib settings, but I am
TOTALLY lost here. I have downloaded the K3 RigCat xml file and Fldigi uses that file. In
the RigCat and hamlib panels, the "Device" is the usbserial-AD02DUIQ mentioned
above.
VOX is turned on and the TX light comes on at the beginning of a text
transmission and off at the end.
PROBLEM:
The text appears in both the receiving and transmitting panels. The text shows
up but the waterfall display stops, the text is sent and then the waterfall
resumes. I get NO SIGNAL on the waterfall and therefore no TRANSMISSION.
This really shouldn't be that difficult. I am missing something major here … I will be
happy to document my journey so that another Mac ham doesn't travel my
"adventure"!
Lost in the bits,
HF Newbie Dave
