[Elecraft] Unusual Phenomenon OT

[Dan Atchison]

I am posting this observation here only because I am using a K3.  I do 
not have any clue what may have caused this phenomenon and I'd like 
someone to give me a rational explanation other than magic!

Just a few minutes ago, I was calling HK0NA on 12M SSB.  I was operating 
split (10 kHz) according to both the rig and the P3.  When I un-keyed 
the radio, I heard RX, of course, BUT ALSO the last several characters 
of my callsign.  In other words, I heard "3 November delta."  Yes, I was 
unkeyed.  There was a delay, like an LDE.

I thought that was strange, of course, but them someone came on 
frequency and said, "November Delta he's operating split."  I was 
operating split!  However, I did hit the split button again (with no 
changes on the rig's display or the P3, and my delayed "echo" subsided 
and I worked the station.  There was no operator error even though many 
of you are currently shaking your heads!  IS IT POSSIBLE that the rig 
was actually transmitting on the VFO A freq instead of the VFO B freq 
regardless of the indications on the rig and P3?

What is going on?  This is, indeed, very strange.  I am also using a 
KPA500 for what it's worth.
