[Elecraft] No Tune Power Output While Split in Data Mode

[AL7CR]

My K3S does this on all bands regardless of wheter it has been power
cycled.  Pressing the tune button while split in data mode keys the
transmitter but produces no output.  Do nothing else but cancel split
mode and pressing tune will then key the transmitter and produce normal
tune output.  I thought it was a strange feature ...
