If you have terminal software available, start it up, set it to 57600 baud, no 
parity, one stopbit and RTS/CTS flow control on whatever serial port you have 
connected to the ORION.  Then send it this command:
XX<cr>  (<cr> is the enter button on the keyboard).  This is the restart 
command.  It should respond with the following:
" ORION STARTED"  (without the ")
If this awakens the radio, then you have a firmware problem - probably a bad 
eprom where the firmware is stored.

I suspect XX<cr> is the first thing the N4PY software does.

I appreciate your remark regarding “waking up”. I  only used that phrase to 
describe what APPEARS to be taking place.

The thing that is confusing is that, once the N4PY software is operated once, 
just to connect and interact with the radio, the radio works fine even after I 
disconnect the N4PY software.

All of the buttons work, the encoders work, even if I disconnect the PC from 
the radio. 

It’s kind of like spraying ether down the throat of a carburetor to get an old 
motor to start. Once started, gasoline sustains its operation just fine.

The only thing that causes the failure to reappear is turning the radio off, 
then back on.

That is what I meant by “waking” the radio CPU-to-encoder/button communications 
via the N4PY software.

Ten Tec has already had their hand at this radio. I do not know how extensively 
they looked at it for its previous owner, but they said it needed a $600 board, 
which they no longer had available. They were not specific about which board, 
but I suspect it was the CPU board. 

I believe the CPU chip itself is good as it functions to make the radio 
operational once the N4PY software has somehow triggered it. Since I have a 
spare CPU board with a bad CPU, I have SOME hope of locating a bad part aside 
from the CPU on the board with the “good” CPU that I could exchange from the 
known bad board if I could determine the path for this data. That is to say, f 
I could determine what path is being formed by the N4PY software to enable 
button/encoder operation.

I have at my disposal several SMD technicians who are fully capable of swapping 
even the big SMD’s without damage.

I am fairly adept at troubleshooting these things when I can get an idea of 
what the designer had in mind when he or she designed hardware and wrote 
software. 

Since I don’t have to pay myself $145/hour to work on this, and since I learn 
something new every time I am successful in fixing something, I look upon this 
effort as a more of a learning experience rather than a profit making venture.

Thus, I am more willing spend the time to find the root cause than, say, a tech 
at Ten Tec, who knows full well that the time to find the root cause would 
exceed the dollar value of the radio fairly quickly at $145/hour.

PS: This one is far too nice to end up as a parts mule…
