I received Bob's launchpad and have found the following:
I am using the Launchpad branch on github.com/AMSAT-NA/PacSatSW
I edited the config.h file to change the pacsat callsign to Ron's call - k0UND
I started testing and found that the launchpad would transmit OK but it didn't receive.
I connected the console and found that the launchpad was resetting every 10 seconds. The reset was precede by "WDxx"
I assumed that the Watchdog was causing the reset and I commented out "#define WATCHDOG ENABLE" This change stopped the resets but it still didn't receive.

It looks like the RX dev 0 FIFOSTAT:00 and FREQ 915300000 Hz could indicate a problem.
Frequency should read FREQ 145835000 Hz
Could this be an AX5043 chip problem?
Any suggestions on what I might do for additional debugging?
Does anyone have an available launchpad I can send to Ron?
