Today I made some more updates Geo-mag observation notes, made up some result sheets and sorted out a modification that has to be made for the fluxgate compass on the theodolite. In the afternoon I fixed a fault with the BGAN satellite phone. After work I installed the new valve in my amplifier and then left it to boil off impurities overnight, and then did some further testing on my faulty Flex 5000.
