[Elecraft] K3 TX light on

[Gene]

On 11/25/09 I downloaded latest firmware, MCU 03.63 and DSP1 02.46.

While using HRD/DM780 for PSK31 I now notice the TX light stays on at 
the end of a transmission.  The light will not go out and the K3 will 
not go into receive unless I tap, xmit, atu tune, rx ant, or ant button.

When using version 3.44 beta release and same setup all  was well.   Has 
something changed in the new firmware that I need to reset or did I do 
something that would cause this?

Thanks,
