K3S glitching on startup

This evening I used my new K3S for a normal session of FT8 (K3S
connected to computer via a single USB cable for both CAT control and
audio transfer), then powered it down.

When I powered it up later, the following occurred:

-- It did not display the normal startup message

-- It rapidly switched from DATA to CW mode, remaining there

-- Started beeping a number of times per second, continuing indefinitely

-- Showed "VOX -- OFF" on the display.

Wondering if this could have been caused by unintended pressure on the
CW paddle, I unplugged it but this made no difference. The K3S continues
to go into this state each time I power it down and restart it. I'm
unable to change mode, band, etc.

Any suggestions for resolving this? Thanks in advance.

73,

This sounds like the K3S is getting commands fed to it when perhaps it shouldn’t be. With that in mind, try:

1) Check the front panel to see if any keys are stuck.
2) Disconnect the serial port then power up the radio.
3) If the above don’t work, reset the parameters. This is described on page 72 of the K3S Owner’s Manual, Rev A1.

And if all that fails, try giving tech support a call.

Re: K3S glitching on startup

Thanks for the advice. Thankfully, there was a very simple solution.
Although I had disconnected the CW paddle, as well as a number of other
cables, I couldn't crane my head around enough to notice that I'd left a
1/4"-to-1/8" adapter in the paddle jack on the back panel, which
apparently had become partially unseated. When that was fixed, the
problem went away.
