I just completed the KAT-100-1. When I started the Initial Tests of the Alignment and Test Steps on Page 27 the ANT1 and LOW lights on the KAT -100 light up, but there is no action from the relays on the KAT-100 when I change bands. I only hear the relays on the KAT2. When I change from ANT1 to ANT2 on the K2, the ANT1 light on the KAT-100 remains lit. Also, when I press tune, the KAT2 relays chatter, the K2 shows a SWR of 1.0 to 1 while the KAT-100's relays are silent and the LEDs show RED, all of the way to the right. I have the ATU setting on the K2 set to AUTO. Also, during this process I upgraded myu firmware from 2.01h to 2.04p and IOC from 1.02 to 1.09.
1) The RF IN on the KAT-100 is connected to the KAT2 ANT1. I have antennas connected to both ANT 1 and ANT 2. 2) I double-checked the Control cable from the male pins on one end to the board mounting on the other end, both ways. By that I mean from the KAT-100 male PINs to the board on the inside of the K2 and vice versa. Everything OK. 3) I double-checked the resistance against the values on Page 17. All were within norms, except for U5 pin 3 (67k vs. 45-55k standard) and U5 pin 5 (104k vs. 45-55k standard). 4) I double-checked that all of the pins of U1 are properly seated. 5) Troubleshooting on page 34 mentions checking Z1 and R5. Both are installed, but other than that I do not know what I should be checking for. How can I tell if U1 is healthy? Any suggestions on an approach to tracking this down will be appreciated. _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
