<Finally> added a sonic to rne04. To mitigate the concern about the holding power of one stake, I attached a "temp" (rope) guy to a reasonably large tree. The tower felt secure while I was on it.
However, the data are garbage. It acts as though the power is low, although the way it is wired the voltage (which measures 11.8V) should have been pretty close. Nevertheless, Andy went back and wire/jumpered it to 24V. Even with that change, the sonic data are garbage.
Tomorrow, we plan to climb again, check the wiring (possible miswired power ground?), and replace the sonic if necessary. I had hoped for this tower to be done, but we still are <just> at 41 towers.
