Can we have a little more info please. Do you have two 15pin cables, one from the K3 to the KAT500 and one from the KAT500 to the KPA500?
Are the cables genuine Elecraft E850463 Aux Interface Cables or are they VGA style cables (which won’t work)? You should not need any other cables connected to the setup apart from power and RF. Page 5 of the KAT500 user manual shows the correct cabling. 73, Alan - G4GNX South Coast UK Elecraft K4D / KPA500 / KAT500 / IC-9700 > On 4 Dec 2023, at 23:18, Peter Iverson <pmiver...@att.net> wrote: > > Here’s the problem: I’ve been successfully running a K3/KPA500/LDG > AT-600ProII with no problems, usually USB and digital modes at about 400W > out.
