My K2 and KPA100/KAT100 have served me for over 10 years now without any problem! After that I made the frequency calibration of K2 I made a mistake when I put contact from KIO2 and KAT2 to Control board. I put the Contact one unit up, pin 3 from KIO2/KAT2 come on pin1 on P4. When I put all together and test, KPA100/KAT100 (both in same EC2) don’t respond. Using Ant ½ I got answer ”PA ANT 1” also when I use menuitem ”ATU” I got the same answer ”PA ANT 1” I hear a relay click in KPA100 when I switch on the radio. Testing single K2/KIO2/KAT2 all work well. Testing K2/KPA100 got 20 W with 1 – 10 W on powerbutton and full power on over 10 W. Can’t change power with the powerbutton. Perhaps U6 on Control Board is out of order! I measure all pin and got som differens against value in the manual. Pin My U6 U6 6 0.0 4.7 10 0.0 5.0 13 0.7 2.3 18 5.0 0.0 25 5.0 0.0 33 0.08 5.0 36 4.6 0.8 39 1.02 0.2 Hope I manage to explain the problem!
