VLF,
Due to the higher ambient temperatures, my power supply interrupts
after quite a short time now, so transmitting makes no sense at these
power levels when the lossy linear PA + supply is located into a closed
aluminium box.
A new PA (H bridge!) and step down converter supply (320V to
0....320V) is almost ready, i'm just waiting for a replacement part to
complete the supply.
Thus i'm now stopping the transmissions on 17470.1 Hz for some time...
