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

[Gary J FollettDukes HiFi]

Now that it has sat a while, it receives.

Knobs and buttons also work.

However, I cannot directly change bands for the main receiver by pushing a band button. Regardless of which receiver is selected, the band button only changes sub receiver band.

Which chip is the firmware ROM? I replaced U500 simply because it was easy (plug in) and no change in operation.

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.

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.
