Hi Ron,

Thanks for your reply!

Which kind of band decoder are you using? How did you connect your K3 with the 2KL? I guess with a single cable from the key out (K3) to the T/R control terminal, right? I´m a bit scared of harming the K3 or 2KL, because of wrong connections. Is there anything else I have to think of?

I´m also using the AT 500 tuner and I sometimes have problems too. Sometimes the tuner does not want to tune at all, so I use a little trick. I engage the internal IC 761 tuner and then the AT500 starts tuning. I turn the internal tuner off and everything works fine.
