I have a feeling I've bumble-fingered something on my KX2 configuration for
CW decoding.

CW decoding is not happening anymore with received signals. Though, oddly,
it's working when I touch the paddles.

As background, I had installed for test purposes Ham Radio Deluxe Software.
After I used it this weekend (well tried to use it) I found my KX2 in an
odd state. This is likely unreleated but it was something I noticed.

Problem: I'm not seeing any CW decoding anymore except when I manually
touch the paddles.

I can hear CW signals coming in strong but no decoding seems to be occuring
for them.

Settings:
MODE: CW
FILTER: .45
CWT: on
Logging: On
Green LED is showing
RX Thr - I've tried from THR1-THR4 - no change
The "T" is showing in the lower right hand corner

Is there some other setting I may have inadvertently changed?

appreciatively
Tom

Re: Elecraft@mailman.qth.net

Is the RF gain all the way up (-0)? Preamp ON? Is the CWT cursor blinking with the received CW? Make sure the filter is centered on the PITCH tone (indicated by the *. Use the SPT to tune the signal.

Just a few thoughts. Hope it helps.

I have found certain instances when using a software program to control
/ communicate with the radio, when closing the software application it
may not terminate correctly and thus leave some odd data in the radio or
leave the radio in questionable or unknown state. This most often
occurs when one shuts down the station, thus turning the radio off
before closing the program. In many cases, a master reset of the radio
corrects the issue.........until next time.

Power up and power down sequence along with software initialization and
termination can be problematic. For the most part I allow the computer
to fully boot, have the radio off but connected to the computer, turn on
the power supply, turn on the radio, load the operating software /
application on the computer. To shut down, close the software /
application on the computer, turn off the radio, turn off the power
supply and finally shut down the computer. Your sequence may vary
somewhat depending on your station configuration.

Tom,

Have you centered the CW signal in the CWT bargraph? That is necessary
- use auto-spot for an easy way to tune the signal to center.
You could try narrowing the filter width to isolate that one signal.

This did it. Problem resolve. Many thanks to all that who responded. This
is one amazing community.

The principle issue was clearly related to running a remote control/logging
software that had radically changed the Kx2 configuration. Many thanks
to Bob McGraw K4TAX for mentioning this and of course Brian your specific
suggestion of checking the PreAmp gain. It has been pushed down to -60db.
And yes I was wondering what the heck happened regarding overall volume of
the radio but I had previous had some antenna issues and propagation has
been weird here (fewer contacts) and so forth.

Anyway, I'm good. I'm grateful.

Tom
