Announcing release of FSM V1.11.

FSM (for Field Strength Meter) is a software application that extends
a conventional SSB receiver to allow measurement and calculation of
field strength of radio signals, noise or interference. FSM is a
software implementation of the technique described by Ed Hare of the
ARRL in "Manual Testing of Field-Strength Levels Using Conventional
Receivers" dated August 2004 .

Version 1.11 revises the algorithm for calculating receive power from
the Step 2 and Step 3 measurements to increase FSM's flexibility and
accuracy at lower measurement levels, allowing measurement of noise
levels with Fa below 0dB.

This has allowed relaxation of some limits that were needed for the
older algorithm, and an associated change to the calibration utility.
Documentation has been updated accordingly.
