K3: Using built in PSK?

[dbp tds.net]

Hi-
 On Tuesday, May 27, 2008 8:58 PM, I sent this message to the reflector and haven't seen any comments... maybe I am too anxious, but I am also anxious to cure this problem- so again, I say:
 
"Hi-
 OK, the K3 works fine using computer generated PSK 31 AFSK, but when I go to
the internally generated PSK 31 D, 31 bps, I do not get responses to my calling
CQ or calling stations. The TX and RX filter width is set to 2.7 KHz. I can copy
perfectly on the radios VFO B copy line and do get a kick out of the auto spot
feature. I can hear the transmitted signal on my other rig (ORION II), but it doesn't have the fullness of the AFSK sent PSK. Any ideas?

 On a related note, one poster mentioned the use of the built in ability of the K3 to notify other net users of external computer problems, maybe so. However when monitoring my AFSK PSK31 signal from the K3 on my OII,  I don't see the AFSK PSK31 signal on the same waterfall of the MixW software. That leads me to believe that you can not switch from computer driven AFSK PSK31 to built in PSK D PSK31 because they are on different frequencies. Tell me I am wrong and tell me how ot make it right.
 Thanks for the bandwidth.

Dave,

Are  you in Data-A mode when using audio based PSK31?  If so, adjust your filter FC
to 1.0.  The BW can be what you want it to be, I normally start mine off at 1.0 kHz.

If you transmit your signal right at 1.0 kHz on the waterfall in Data-A it should
be the same as when using PSK-D.  PSK-D uses a default of 1.0 kHz.  But it creates
its own audio tones instead of using an external soundcard.  

If when you are using Data-A you are somewhere other than 1.0 kHz for your audio,
then no, the PSK-D signal will not be at the same place, it will always be at 1.0
kHz.  Also, when using PSK-D you do not need to adjust the filter FC, it will
already be at 1.0 by default.

Hmm, I responded with this message:

http://www.nabble.com/Re%3A-K3%3A-Using-built-in-PSK--p17503377.html

Since you remarked that when you monitored your transmitted signal it
didn't have "fullness" I thought that you might be sending only an
idle signal, which would be the case if you were trying to key the rig
with an ordinary key, rather than paddles.

I assume that he's using recent firmware. Up until a couple of months ago, the K3 internal PSK31 produced what sounded a bit like PSK31 but was actually gibberish.

I really haven't bothered with the paddle-generated PSK mode, but I did test it recently by monitoring on another receiver and it decoded OK. There have been a couple of updates since then, though.
