[TenTec] What is your software doing when it "initializes radio"?

[Howard Smith]

The Firmware Verison is actually important to this discussion. There 
have been many firmware versions over the lifetime of the Orion.  
Version 1.x and 2.x have major differences.  Version 3.x merged the 
firmware from the Orion and the Orion 2 into a common set of code.  
However, the Orion and Orion 2 still have their individual firmware 
files, and hence the slight differences in the firmware versions.

The Orion Programmer's reference manual was not always kept current with 
the firmware versions, so its information may not be valid for the 
version under consideration.

What is the firmware version installed in the Orion in this discussion?  
The firmware version is displayed at startup, and also by Pressing and 
Holding the MENU key.

In the discussion, it was stated that if the Orion was powered down and 
then immediately powered back up, it would still work.  This is a big 
clue that suggests that the internal battery for the Battery Backed SRAM 
may have failed.  There is enough bypass caps to support the Battery 
Backed SRAM for a short period of time even if the internal battery has 
failed.
