VLF,

This evening and night i'm planning to transmit on 5.755 kHz<= /u>, using the large antenna, the large coil and the large PA :-)
I don't know what can be expected and how the system works at that frequency. Actually it is just a first test for playing arround and doing some measurements :-)
If some nearby stations want to give it a try, maybe even in 3HD, then don't hesitate :-)
