Jim,

The receiver frequency for each chip is stored in MRAM.  So if you have them set to the same frequency that will stay there.  You need to reset the MRAM to get the defaults.

I think a ranging error will show up at boot, printed in the console, but I could be wrong.

Bob,

I finally got everything back in place and brought Blinky up last night.
I'm getting a ranging error on device 0 and no messages from the others.
Same when I attempt the rx command.
All four receivers are showing the same frequency.

I checked this morning and I'm not running the latest code so have it
downloaded and will test tonight if possible.
If it goes well, I'll look into your question.  Technically all four
receives should have the same PLL value as the PLL should range over the two
meter band.
I'll look at that as well.  Have to deep dive into the manual.

I'm suffering from a stiff neck this week and not able to do much.  Always
something!

Looking at the feedback from the reading the AX5043 devices I see two have
different PLL vales. The PLL sets the frequency conditions so this may be
involved with the two devices that do not seem to be working.

A listing of the register values reported is attached.

Also the code I think is setting these registers. I have not had time to dig
into the code. If an issue can be seen by someone that has looked at this
code I would appreciate the help.


Bob
