[Howard Smith]

Hi Petr,

This is the list of changes for the Orion II (566) firmware, Version 
V3.033xe:

2015-12-22Version V3.033xe

==============================================

For this release, it is necessary to do the full Master Reset/RAM Clear 
sequence after the
firmware is updated.

1. Download the new installer update file, which will force a Master Reset.
2. Power Down radio.
3. Perform a Master Reset.
4. Power Down radio.
5. Perform a RAM Clear.
6. Power Down radio.
7. Perform a Master Reset.
8. Power Down radio.
9. Power Up radio, and ready to use.

Changes include:

These changes apply to the Main Rx only. The Sub Rx was not changed.

1-Added selection of S-Meter input to Other Menu. Selection is AGC Level 
or RF Signal.
Default is AGC Level. AGC Level means the S-meter will not go lower than 
the AGC
Threshold/Knee; RF Signal means that the S-Meter indicates the signal 
strength at the antenna,
regardless of current AGC threshold or action. Selection is retained 
over power cycles.

2-S-meter reading is compensated for ATTN setting, Preamp setting, 
signal reduction caused by
the analog hardware AGC with strong (> S-9+35) signals, and the RF Gain 
control.

3-S-meter is calibrated so S-9 is 50 uV across 50 Ohms at the antenna 
terminals.

4-S-meter calibration routine updated to correct for a missing step in 
the table.

5-S-meter ballistics follow the Hang Time and Decay Rate of currently 
selected AGC profile.

Other changes:

6-Forced NOTCH to always be OFF after a power cycle.This fixed the 
problem with the DSPs crashing if both NB and NOTCH were enabled during 
a power cycle.

7-Fixed Serial Command *BS+1

If you get the update and install it, there will be a file named 
566History.pdf which contains the changes for all versions.
