Encouraged by our last experiments with ground dipoles we decided to do a transmit experiment with this antenna on VLF 8.270kHz, 36km (36000m) wavelength. Thanks to Fab LAB Trójmiasto we had a great location on the see on a cliff near the Baltic Sea in Gdynia. Our goals for this experiment were:
Try transmitting from a ground dipole on VLF
Assess the field strength near the sea
See if it is possible to reach greater distances with relatively simple equipment and low power.
Joe VO1NA transmitted on 21 december 2017 at 8270.0075Hz.His transmission was succesfuly received in Warsaw (RX Jacek/SQ5BPF), at a distance of about 5100km. This is the first succesful reception of a signal from Canada in Poland at 8270Hz.
