[TenTec] 2.031 QSK bug - this is not a bug

[Gene Henderson]

This happened to me also. Radio was in the receive mode but the centurion 
amp was indicating that it was transmitting as the transmit light was on and 
I was seeing plate current. I have reloaded the 2.31 software and the 
problem has left for now.   Gene WB9HLA
