If your TX sensor is in line after the KAT500, you might be observing the SWR of the antenna side of the ATU. The KPA500 and KAT500 LEDs show the SWR at the transmitter side of the ATU, rather than the antenna side.
The KAT500 Utility will show the "bypass VSWR", which is the SWR observed by the ATU when it is in Bypass. 73 de Dick, K6KR -----Original Message----- From: Elecraft [mailto:[email protected]] On Behalf Of Joe K2UF Sent: Wednesday, September 14, 2016 11:49 To: [email protected] Subject: [Elecraft] SWR question Using my K3/KPA500/KAT500/P3+SVGA with the TX sensor in line. On the KPA500 the SWR reads 1.3 with one or two SWR led's lit also one or two led's lit on the KAT500 but the SWR display on the P3 shows about 6. Any ideas why this is happening?
