Thanks Lyle, I put my stepped attenuator in the line between the K3 and the XG2 and checked the S-meter. The way I had it calibrated, a 3dB step took it from S9 down to S8. I re-calibrated the S-meter offset until the meter read S9 and a 6dB step was required to take it to S8. (Offset value went from 22 down to 20)
Now I don't see an S-unit of change with the blanker in and out and using your method, I read 2.8 dB of insertion loss. Higher than yours but not quite as troublesome.

I measure 2.0 dB (AGC OFF, using AFV/dBV internal functions and monitoring a steady nominal S5 carrier on 6 meters). 73, Lyle KK7P ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
