[Elecraft] K2: Very low output on 160m

[Ken Alexander]

Hi Don,

OK, the tests are underway.

Key down signal @ pin 4, U10:  80m; 0.058  160m; 0.055
Key down signal @ pin 6, U9:  80m; 0.205  160m; 0.695
Key down signal @ W6:  80m; 0.025  160m; 0.018
Key down signal @ D1 anode:  80m; 0.023  160m; 0.016

I remember a thread a long time ago about what is
considered a "normal" reading, and I recall that range
of what was considered acceptable was much larger than
I would have thought.  Thus, I will leave the
interpretation of this data to you, with my thanks!

73 - Ken
