I'm querying the group regarding the NUE-PSK settings and an Elecraft K3
... I'm having some trouble getting the transmit settings correctly.
Here's what I've done so far ... after Googling, reading, and
experimenting ...
MODE: Data A
Power set at 20 watts
Line Out is from the back of the K3 with the Lin Out menu setting at 20
Line In is to the mic jack wired like NUE-PSK cabling document suggests.
Line In menu setting is FP:L (Front Panel Low and no bias)
Mic Gain is 30 ... I put the K3 into TX Test mode, then F8 on the modem
to throw it into transmit. I adjusted the Mic Gain and the NUE pot to
get barely one bar on the ALC meter. Any more ALC than this causes the
K3 to show ALC spikes episodically to 6+ bars with great transmit sound
distortion. I can only imagine how the signal looks.
Through Google, I found several folks doing different types of setups
with the K3, so I read all their suggestions and tried to adapt them. I
never did get the "4 bars of ALC" setting to be satisfactory. It seemed
that I was greatly overdriving the output. On the other hand, the
NUE-PSK information about the K3 suggests no ALC bars showing.
The above settings give me 1 bar on the RF out ... so 10 watts or less.
I didn't get any responses on 20meters this morning to CQ so I don't
have any feedback on proper settings. Does anyone have any other
suggestions for the K3 setup?
Finally, I'm not a beginner with PSK31, but I am new to this interface
with the K3 ... I have searched the Elecraft relector archives but
didn't find anything specific to the NUE-PSK ...
Thanks in advance. I take the Digest so will take awhile to respond,
unless you respond off list ...
