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.

Pacsat>get ax5043 status provided:

AX5043 dev 1 TX:
  FIFOSTAT: 21

  XTALCAP: 0

  PLLCPI: 10
  PLLVCOI: 97

AX5043 dev 0 RX:
  FIFOSTAT: 00
  PWRMODE: 05
  XTALCAP: 0
  PLLLOOP: 09
  PLLCPI: 08
  PLLVCOI: 97

  PLLVCODIV: 30
  FREQ 915300000 Hz
  MODULATION: 8
  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?

Bill
