I also looked for a solution to the S meter calibration problem. I
discussed the problem with Greg Ordy w8wwv Author of the great
program called S meter light. Unfortunately the K2 does not return

One possibility for an "add in" S-meter module would be an AD8307 log
amp module paralleling the IF amplifier's input. This will give you an
honest 80 to 90 dB linear output (db in, linear output), if you can
manage the shielding, and close to 100 dB if you don't mind a bit of
non-linearity at
I rarely look at my S-Meter. Either I can hear them, or not.
Since most signal reports have nothing in common with reality, it
Just doesn't matter.

If all S meters could be referred to uV/m on an isotropic dipole there might be
some meaning to the readings. It's nice for relative measurements when someone
else is tuning and pruning.

Boy Jack, if there was some small kit that could sample a signal in the
K2 and send something out the back that could drive the LDG S-meter that
would be great. It would be even greater if it could just plug into the
K2 using one of the option slots.

I'm not sure how crowded the 75/80M SSB band is at any
given time. I can speak on contest conditions on 80
CW. Basically you have 3 major DX contests that will
pack 80 CW: ARRL DX, CQ WW DX, CQ WPX (ARRL SS also
packs the band on this side of the pond). DX is all
over the lower 100 khz of 80, so th

I find the K2 to be excellent on SSB mode, for ragchewing and DX hunting.
I almost never operate CW any more due to medical problems.

Hmm, using the full bar graph to show S1 to S9? Not a bad idea. I may
do that once I get the 41 step attenuator.

If the latest FCC FPRM holds with no changes, I think the 80 meter people will
be in trouble. So far on 80, we haven't had much of a "digital vs. CW"
conflict. Most digital ops are above 3600 and most CW ops below 3600

Firstly, I want to state I do not imply that the RTTY bunch has run away
with 40 meters. All in all, they have, along with the other digital modes,
pretty much stayed within the "sub band"/band plan "Gentlemen's
