[Elecraft] [K3] Short TX burst when changing mode from Data to AM

[Karza]

Hi,

When I change mode of my K3 #310 from Data to AM
using the "Mode <down>" -button, a short
( abt 1 second ) TX burst gets sent out.
Burst power is roughly 1/5 of the requested
output power.

This happnens if VOX Gain is set to about 20 or
higher and even when there are no mic-, data- or
RS232-cables connected.

I'm running MCU 2.76 with DSP 1.98

Anyone else noticed this?
