Data from the 7m TRH has been intermittent for more than a month.
Here's a typical dropout, where the unit quits reporting, then 15
hours later comes alive, with startup messages:

Email from Ned:
the TRH at 7m now seems to be re-appearing during the night time and then at about 8am it drops out again...

My guess is that it is a power problem, either in the cable, or corrosion in the unit. This unit and
