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.

AX5043 dev 1 TX:  FIFOSTAT: 21  PWRMODE:: 0d  XTALCAP: 0  PLLLOOP: 0a  PLLCPI: 10  PLLVCOI: 97  PLLRANGINGA: 49  PLLVCODIV: 24  FREQ 435759999 Hz  MODULATION: a  TXPWRCOEFFB0: 20  TXPWRCOEFFB1: 0

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?
