Could you have the KPA500 key line pulled low when receiving? That would activate its T/R switch (even during receive).
Try temporarily removing the PTT key line RCA connector from the back of the KPA500 to see if the signal improves. If it does, try to figure out why it's shorted during receive. Perhaps it's plugged into the wrong connector on the back of your TS2000? Good hunting! 73 de Dick, K6KR -----Original Message----- From: Elecraft [mailto:[email protected]] On Behalf Of Jerry Sent: Saturday, September 06, 2014 4:18 AM To: [email protected] Subject: [Elecraft] Ts-2000 and the KPA Greetings: My K3 is on its way back to Elecraft for some needed repairs. So I have placed my TS2000 into temporary duty. I have hooked it up to the KPA500 and the KAT500 and it works very well in the transmitting mode. The problem arises when I am in receive. If the KPA500 is in the STBY mode, receiving is not inhibited at all (I get everything noise and all). When I place the KPA500 into OPER (full power), the receive signal is attenuated down about 20db. Great for reducing noise, but not so good on that rare dx station. This same condition persists when I take the KAT500 out of line. Am I missing something in the setup when I connected the TS-2000? I do have a recording of the differences between the two settings and it is certainly available to anyone who would like it to analyze. Just let me know off reflector and I will send it to you.
