Finally got to make up an LED tester for both the Band0-3 and Digout1. Everything looks fine. No problems selecting two antennas on all bands 160-6M. I have the built in 2M transverter. On 2M I get 0000, the same as on 60M. But 2M selects Ant3. So I don't think there will be any problems. Next phase later this week when I hook up the BCD-14 board. 73, N2TK, Tony

Easy enough ... 4 NPN transistors - base to BAND0-3 pins, LED and limiting resistor between +13.8 and collector of the transistors, emitter of the transistor to ground. > The 0000 output on the KIO3 for 60M has me concerned. Don't know why it should concern you. 0000 is just another state and I don't see 0000 used for any other band *or* any transverter band. Your bigger concern might be the reuse of one of the other band values for 2 Meters depending on how you decode HF vs. the transverter bands. 73, ...
