...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 :-)

...carrier stopped 14:49 UTC. Need to check the site before continuing. Unfortunately no transmission tonite...
