I just used a step attenuator to do a crude check on my K3. Throwing in a few dB to "match" the 160-meter dipole on the BC band, and tuning in an S9+40 dB signal, switching in 40 dB attenuation in two 20 dB steps shows, within reading accuracy S9+20 and S9 respectively.
Using my XG2 on 20-meters with full output at S9 (cal point) adding 6 dB attenuation at a time shows one S-unit steps down to about S4 or so.

First, while the "official" definition of an S-unit is 6dB, one S-unit on most receivers is more like 3-4 dB. While I haven't done a linearity test on the K3 S-meter, I suspect it's a bit better. ______________________________________________________________ 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 Message delivered to [email protected]
