Steve, I would try another sensor before digging into the W2 proper.

Hi everyone, I have a W2 Watt meter and 2KW sensor that I haven't used for some time. I loaned it out to a club mate who reported it DOA. The unit self-tests OK and I've swapped the 8 way RJ45 cable for an out of the packet new one. I've tested it thoroughly on my bench and have found a few issues that I would like help resolving: When the sensor is plugged into port 1 I get full scale (high) SWR with no rf applied. When RF is applied no forward power is registered. When I plug the sensor into port 2, the meter functions, but 100W input from my K2 is reported as 80W. I have checked the K2 with other power meters and the all say 100W +/- 5%. The W2 also reports an SWR of 1.5:1 when I use any of my dummy loads (or antennas!). They can't all be bad on every HF band!
