Dear Dr MC,

You wrote:

"In general, there is no reason why the S-meter should not work when the AGC
is turned off. One can disconnect the AGC control point and leave the meter
still connected to measure the AGC voltage. You only need to disconnect the
control line, not the line to the S-meter. This way, the S-meter still works
but the AGC does not."

As you point out this works in some designs but in the K2 and other designs I am familiar with the S meter is in the AGC
control loop so that its response is calibrated when the loop gain is taken into consideration.  If you open the loop
after the meter the meter will be overly sensitive.
