Finished my KAT-100-1 last night. Seems to be working FB. I get a little RF in to it on 40m, and it causes the K2 to reset. Read the tips in trouble shooting about how to cure that. It works fine on 40 if I cut the power back to 5 watts or so. Great kit. Went together quickly. Not too many moving parts to this one. Hi hi. Stan Rife W5EWA Houston, TX K2 S/N 4216
