K3 CWT Function with firmware MCU 4.60 / DSP 2.80

[Chad Wasinger]

Has anyone experienced any issues with not decoding a good cw signal via the CWT function on firmware version 4.60/2.80? I've been running the older 4.48 which is the best firmware I've seen for the CWT function to work properly. I did note that the 4.60 firmware had some fixes in it for the CWT function, yet I'm not having any luck making it work right. I've tried all the recommend settings as well. When I revert back to 4.48, all is good. Also, my KX3 is spot on with the CW decoding. I thought possibly my AGC menu's might need adjusted but looks like this new release has it's own independent AGC algorithms.
Suggestions?
Thanks,ChadN0YK

CWT is not working as well in 4.61 either.  It doesn't hit zero beat
within 4 Hz.  It used to be spot on.  This observation was made and
posted here when 4.61 came out.

4Hz..... For one who offsets with XIT 50-60Hz in a simplex pileup to
avoid the zero beat mush this tiny error is of no consequence.  Oops,
have I just given away another pileup busting secret?  I'll keep to
myself whether it is a high or low offset.

It has never been consistently any better than 5 Hz (the target for  
this feature) in any version. Accuracy varies with band noise, filter  
bandwidth, QSB, etc. If you were getting "spot on" in a previous  
release, it must be all in the wrist :)

I have had very good success decoding CW by adjusting the RF Gain. I think it is actually better with the latest firmware than in the past.
