[Elecraft] K3 S meter

> In my view the K3 S meter is simply far too sensitive at the lower end.

I do not think so. Some band/antenna/QTH combinations will on a *good*  
S-Meter show fairly high S values for band noise. Without wanting to  
reopen the S-Meter mail wars of from the days after the announcement  
of the K3. There is a norm: IARU Region 1 Technical Recommendation  
R.1. Ninety-nine percent of all S-Meters are *not good* i.e. are not  
in accordance with the norm.

=====================================================================
1. One S-unit corresponds to a signal level difference of 6 dB,

2. On the bands below 30 MHz a meter deviation of S-9 corresponds
to an available power of -73 dBm from a continuous wave signal
generator connected to the receiver input terminals,

3. On the bands above 30 MHz this available power shall be -93 dBm,

s4. The metering system shall be based on quasi-peak detection
with an attack time of 10 msec ? 2 msec and a decay time constant
of at least 500 msec.
