Setting up Multitech Conduit Gateway for TTN

@Batilan Thanks! That fixed my problem. Now if I had only asked a day ago I would have more hair

There is one oddity though. My messages are getting through perfectly but my CRC is seldom 100% - i.e.

Message gets through:

{
    "data_raw": "QAA+AQIADgABSHuBh0kALLWLNXtzI6XoxGs9ENXEgswSO7pdw7vC",
    "gateway_eui": "0080000000009CB4",
    "node_eui": "02013E00",
    "frequency": 912.3,
    "data_plain": "Hello number 3 from Natick",
    "time": "2016-01-05T18:12:49.685Z",
    "rssi": -93,
    "snr": -6.2,
    "datarate": "SF9BW125",
    "data": "SGVsbG8gbnVtYmVyIDMgZnJvbSBOYXRpY2s="
},

and I get the following in the log.

I also get a log update every 30 seconds now:
