Rick and I were out to do this today (5 may). Gordon had set up the config yesterday, so it was plug and play. The mast was down from about 10:12 to 11:15 to do this (it took a while to fish the data cable through).
In addition I:
added a blue cap to the TRH bluetooth connector (I had noticed it was missing during our last trip)
installed a "double shield" insert around the Tirga thermistor.
