[Elecraft] Transmit when switching from DATA to AM mode?

[Roger Marrotte]

I just tried to recreate this and did not see it happen.  No messages of any
kind showed up on the front panel of the K3 and there were not any changes
to the meters on the attached power supply.

K3 #1192
MCU 2.76
AM Filter installed
Tried in and out of band
With PTT and VOX on
A microphone is connected but it is connected at the back of the radio.

|Hi all,
|
|I've just discovered something odd with my K3 (#1772).  When I switch mode
from DATA to AM via the front panel Mode button, the rig tries to transmit.
The red TX light comes on momentarily and I get a |ERR TXF message (if in
band) or an END message (if out of band) in the VFO B area.  I don't have
the AM filter installed, so I don't think anything is actually going out
over the air, but it doesn't seem |like the rig should ever go into transmit
on a mere mode change.
|
|It ONLY happens when going from DATA to AM, not when going from FM to AM or
between any other modes in either direction.  There is no mic connected to
the rig, nor anything connected to the rear panel |mic or line inputs.  The
only things connected to the rig are a paddle, an 
|external speaker, and the antenna.   It happens whether in VOX or PTT mode.
|
|I first noticed it with MCU 2.67 (although I can't say if it happened with
earlier versions.)  I've updated to the 2.76 beta release and it still
happens.
|
|Anyone else see this?
