Just finished another K-1 build, but have a problem with the KFL-2, the 2 Band Filter board. I had built this board for 80 and 15 meter use.
Symptoms: E27 message on power up No relays clicking Testing: Confirmed solder connections Confirmed component placement Confirmed plugged into all 3 sockets U1 Voltage testing found 6 volts present on pin 14, no voltage present on pin 1 Removed U1 and inspected pins, all are full inserted into socket. Conclusions: Defective U1 chip? Does this make sense to everyone, or I have overlooked something here? I don't have another 2 Band board for testing, but I did substitute a 4 band board, which I built at the same time, it operates just fine. Cordially, Bruce J.
