PSK D Mode and random characters in received window...

[N2ZDB-2]

Hello K3 users,  

I am using PSK D Mode on my K3 along with the K3's Utilities Terminal  
Program and have a few questions:

Threshold does not seem to work in "TEXT DEC". I still get many characters  
coming thru in the Terminal Program's receive window. I have tried a "thr
30"  and it doesn't even seem to make any difference!

Also noticed that if I use squelch the characters are still coming thru  
even though the receiver's speaker is muted! Is this normal?

Any idea how to stop these random noise characters from showing up when no  
one is transmitting a PSK signal?

I still need some more roofing filters in my K3. Currently I only have the  
2.8KHz 8-pole filter and am narrowing the bandwidth using the DSP.

Thank you,

73's Michael

Michael,

Threshold is not used in the present DSP firmware for PSK D mode.

Squelch is applied to the audio after the PSK detector, so it also has
no effect.

Thanks you for these reminders, I'll look at improving this in the DSP
firmware.
