Hello Uwe, VLF

 

The trace at 8270.015 Hz in my grabber is my own local backyard DX signal.

A notebook output at 3 m wire that TX in my home.

RX antenna in backyard at 20 m distance.

 

Btw;

You'r TX went QSY 0.001 Hz up :-)

Hi all,

During my last emissions  on VLF the antenna system was not resonant anymore because I took the top of a huge tree down. some twigs did contact top wires.

I thought that would make abt 10Hz off resonance and there was no need to do anything.

Today – we had a nice sunny day - I measured  the resonant point and found it was plus 200Hz off. The FS meter – RYCOM 1307A – jumped from -4dBrel to 0,5dBrel when resonating the system to 8970Hz agn.

The TX is ZOA agn since 1710utc. Phase correction and NMEA decoding on.
