Hallo Bill,
user-programmable. We now have the opportunity, given this new feature,
to experiment and see what really works best, and make a LOGICAL case
for establishing that as a standard.
6dB makes a lot of sense to me: 1 S-unit = 6db = factor 2 in voltage.
This is the Region 1 recommendation:
------------------------------------------
IARU Region 1 Technical Recommendation R.1
BRIGHTON 1981, TORREMOLINOS 1990
STANDARDISATION OF S-METER READINGS
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,
4. 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.
------------------------------------------
But *MUCH, MUCH* better is Wayne's plan to display dBm.
I do wonder what timing Wayne will use.
