Steve, There was a 'safety valve' added to the K3 a while back that prevented RF if the K3 was turned on while PTT or a closed Key was found. Apparently, the timing of both the K3 power on and your PC boot were close enough to activate that 'safety valve', but in an unusual manner.
Note 'safety valve' is a label of my invention - you will not find that term in the manual. 73, Don W3FPR Steve Ellington wrote: > Yesterday I changed PTT-KEY to OFF- DTR so Logger32 would be able to key via > RS232.
