Spent a long day troubleshooting.

1. Reinitialized the RTC. Froze. Disassembled the whole Rx set outside of the metal case and ran it 'naked' on the bench. Froze just after restart.

2. Connect to another computer with Windows 7 - also froze.

3. Discovered that it also froze with no USB cable connected.

4. Remelted and applied more solder to major components.

5. Swapped nano boards and reprogrammed between Tx & Rx unit - still freezing.

6. Replaced RTC module and initialized. Now the RTC EEPROM is listed on I2C memory scanner! Original RTC must have been faulty. Froze when reconnecting USB only.

7. Applied more solder around logger chip.

8. Not freezing now when only connected to 12 volt. Logger is working in this mode. Changed archive to 1 minute so I did not have to wait so long for testing.

9. Occasional freeze when reconnecting USB. Seems ok once restarted and stabilized. Tested several times disconnecting Cumulus and USB, but leaving 12 volts applied. Each reconnect of USB and Cumulus restarts downloaded several fresh archives. Reassembled into box.

So waiting for new USB cable. I think I am about to order an FTDI board.

This is now my full I2C scan result since replacing the RTC:
Scanning...
I2C device found at address 0x27 !
I2C device found at address 0x57 !
I2C device found at address 0x68 !
I2C device found at address 0x77 !
done
