Good point Tom, To be honest I had not even considered that. I have my KPA100 installed with the KAT100 in an EC2 case. Looking at the clearance left by the KPA100 in the EC2 case I doubt that there is enough head room above the KSB2 if the amplifier were mounted in the K2. There are precious few spaces left to put anything. I need my VOX to work the way I want, so compromises must be made. I guess the solution could be done in SMD, but that's rather against the K2 ethic. 73 Stewart G3RXQ _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
