I buy black static free "sponge" abt 6x6 from RS (same as used to ship IC's) and plug parts by type into it. I end up with 3 squares for a K2 size project. Very easy to find parts fast. BTW I hope all are noticing that K line is showing up as predominant rig in QRP contests. Check out score pages in QRP Quartly. Tim O'Rourke KG4CHX
