K3 and JT65

Hello

I am trying JT65. Two audio cables from LINE IN and OUT in the K3 to phones
and mic in the computer

I can see decoding on the software, but I cannot get RF out. The K3 go to
TX, but I think is not sending RF. I increase RF while TX and I dont see RF
out on the K3 smeter

Any help?

thanks,
Jorge

Re: K3 and JT65

Jorge,

JT65 is "just another data mode", and like other data modes, you must
drive the K3 audio up until you have 4 bars solid on the ALC meter with
the 5th bar flashing.
Adjust the computer soundcard output and the K3 LINE IN Gain to achieve
that condition. You do not have to transmit while making that
adjustment, set the K3 to TX TEST or turn the power to zero.

Then adjust your desired power level with the power knob.

I know this differs from the common internet (and some software
instructions) which say to set the power to full and use the audio level
to control the power. That advice is for rigs other than Elecraft.
That does not work with the K3 (or other Elecraft rigs).
Elecraft controls the power differently than other transceivers - the
firmware adjusts to the power set with the power knob rather than merely
controlling the drive with a knob.

Re: K3 and JT65

Thanks Don

what mode do you use? DATA - DATA A? USB?

In USB mode with MIC know I adjust LINE but no bars on the ALC meter.
Maybe something with the notebook soundcard, thats is very hard for me. I
will trying to figure out about the computer, or try to get a USB external
soundcard

thanks,
Jorge

Re: K3 and JT65

Jorge,

As with all data modes, use DATA A. It should be the same as USB, but
with compression and TX EQ disabled.

The DATA A mode MIC SEL should be set to LINE.

Adjust the computer soundcard output to at least 75% and then adjust the
MIC Gain (actually Line in gain) to achieve the proper number of ALC bars.
