I just bought an FH-1 keypad that I intended to use as a contest keyer, and when I try to use it as such on my MkV, the CW memories seem to overwrite each other. I can't get it to work reliably. Has anyone else seen this problem? Is it a bad FH-1 or a bad MkV? (Yes, I have set the menu option to "keyer".) Brian, W0DZ
