Jukka,
I'm having a similar problem with another digital voice keyer. Mine appears
to
be a ground loop caused when I hook up the laptop computer. It is a high
pitched tone that is probably from the switching power supply. I am
suspecting
the audio path I am using, as I have tied the mic ground and chassis ground
together in my FT990. I am going to pickup a 1:1 transformer from Radio Shack
today to isolate the microphone ground and the PTT ground. I have found that
my FT990 is fairly vunerable to RFI, especially when I have the likes of an
earphone
plug partially plugged in.
Let me know how you make out. Also, if anyone else has run into this and
solved
it, I would appreciate hearing of your experience.

With due respect but I cant for my life understand what this has to do on a
international contest reflector. Maybe Im stupid but so be it.
