[Elecraft] K2 rev B sensitivity - measurements look ok!

[Wallace, Andy]

OK, took some sig gen measurements. Recall that the ARRL K2 review said that
an
S-9 reading was with 115 uV in on 20m, preamp off, and 19 uV, preamp on.
Here
are my results for all bands:

80	115	21
40	115	17
30	100	17
20	125	20
17	125	22
15	130	25
12	150	26
10	140	21

The minimum discernible signal on 80m seems to be less than 0.1 uV. This was
with the S meter hi cal = 018 and s meter low cal = 179 (done on 40m, no
antenna, preamp off). 

The numbers above were with FL1 set to 1.5 kHz. 

Some loss up around 12/10 but that could also be loss in the old BNC cable
from
my signal generator, or the sig gen itself. Been years since I used or
calibrated it so I should check it with a scope to see if the attenuator
is accurate. 

Overall, I think it matches the ARRL spec close enough. Guess it's not deaf
after all. If anyone else wants to check theirs after all, I'd like to
hear what your numbers are.
