25m near and 20m rim TRH's have been reporting values of 0 for their fan currents.
I tried rserial to both TRHs and doing a ctrl-R, but that didn't help. The TRH's did not respond with their reboot message. The only effect was to stop the data, which only resumed after hitting CR several times.
I could power cycle the TRH at near with "eio 14 0", "eio 14 1" commands, so that Ifan.25m.near is now about 40.
Power cycling the TRH at rim (eio 15 0/1) didn't work, it continued to report wheh supposidly powered down. That port must not be FET controlled.
