Re: [Elecraft] [K2] KAT100 error
Damon, First, remove the KPA100 from the picture (remove it from the EC2 enclosure) and connect the KAT100 directly to the base K2 and see if it works OK - if my suspicion is correct, it will. If the KAT100 checks out, then check 2 things - first diodes D16 and D17 in the KPA100 and the short coax you are using between the KPA100 and the KAT100. Let me know what you find. 73, Don W3FPR W4HDM wrote: My KAT100 was working fine then developed a problem recently. For those wondering what happened to my for sale listing this is why I removed it.

Re: [Elecraft] [K2] KAT100 error
Don, Ok I removed the KPA100 and connected directly to the K2, I also tested with 2 different jumpers, as well as useing the RF in and the AUX connection. All give the same results: KAT100's relays sound and the K2 shows 1.0-1 swr. Lights on the KAT100 do not light up on tune or TX. K2 reduced power on key up (at 10 watts setting and 5 watt setting). Occasionally I get a High Current message. Current set at 3.50 I checked the RS232 for continuity and it is OK. I started doing the test in the KAT100 Manual. When I set the antenna to 2 and turn off the K2 and then back on I noted the antenna back on ANT 1 I also noticed when first powered up the lights on the KAT100 are bright but then dim a bit. Maybe this will point towards the problem? I suspect I have a bad solder point somewhere in the KAT100.

Re: [Elecraft] [K2] KAT100 error
Damon, Thanks for removing the KPA100 from the picture, now we know the problem is the KAT100 or the base K2. To eliminate the base K2 from suspicion, test it into a dummy load and see if the HiCUR messages are still present. While looking for solder problems, first check pin 1 of the KAT100 firmware socket. What you are describing sounds a lot like a problem with the firmware chip. 73, Don W3FPR W4HDM wrote: Don, Ok I removed the KPA100 and connected directly to the K2, I also tested with 2 different jumpers, as well as useing the RF in and the AUX connection.
