Ok, glad the MRAM is working.  Any chance that you don't have the two jumpers on the LaunchPad required to power the 5043s?  These would be a pair on the right (components up, USB down, I think) just below the bottom set of pins.  

BTW, I don't even try to push Jim's board all the way on.  It is tight as it is and I want to be able to get it back off (relatively) easily.    But regardess, the tops of the pins are all level, even though the newly soldered pins have a plastic holder at the bottom and the original pins do not.

Burns sent me the info on that.  I ran J5 pin 12 to a via on the
bottom right of U1.  After doing that wiring change, all but one MRAM
appears to be working.  It looks like R5 got removed somehow, I may
have done that removing the wire.  I just installed a bridge there,
since it's a zero-ohm resistor, and the mram seems to be working now.

The temperature sensor on the daughter board seems to be working.

I don't think the 5043's are working.  I'm not getting anything on
transmit, and I eventually get:

Pacsat>send pb status
## SELF TEST: pb_test_status
TX QUEUE FULL: Could not add UI frame to Packet Queue
PB Empty.
## PASSED SELF TEST: pb_test_status

after running that a few times.  At startup, I'm getting:

ERROR: In start_rx, axradio_init returned: 5
ERROR: In start_tx, axradio_init_70cm returned: 5Initializing PB Task
ERROR: Failed in init PB Status Timer
