Betreff: VLF: Carrier on 6470.005 Hz=

Hello dear friends of the Very Low Frequencies,

Now i'm down on 6470 Hz again. So far the antenna current is limited by the PA, somehow, obviously one of the transformers does not transfer enough current on this frequency. The antenna current is 460 mA. The actual goal is to get 500 mA, maybe 540 mA.
The carrier is on the air since 20:42 UTC on 6470.005 Hz.
Relative to my 8270 Hz signal, this one is 7.8 dB weaker. But relative to my last experiments on 6470 Hz, now the signal is 6.2 dB stronger.
The carrier will run several hours, protected to 450 mA.

If all works well, i will run an EbNaut message tomorrow evening.

Reports welcome.

73, Stefan
