...a visual inspection of the TX site showed no sign of arcing or other 
unwanted effects. The actual resonance frequency is at 5140 Hz, so it 
will be pulled further down when rain starts to fall. This has obviously 
tripped the safety function yesterday. The top of the coil is currently 
touching the top of the housing where it stays in. Thus, the detuning by 
rain is even more expressed. This will be solved in the next days..

The carrier is now back on *5170.005 Hz until 16 UTC*. Then, the 1 
character message will start for a 2nd time. Alex said he will be in the 
garden again tomorrow, so there will be 2 files to stack and try to get 
a decode :-)
