VLF 18khz to 100khz on my AOR-5000 receiver

Описание к видео VLF 18khz to 100khz on my AOR-5000 receiver

ELF and VLF Reception here at my location in Melbourne Using my AOR-5000 receiver with Collins filters set at CW 500Hz bandwidth. This reciever works very well down to 5khz but I cant find anything below 18Khz other than noise and signals that i cant identify.
Tunning from 18khz to 100Khz. Using a SDR-IQ I often see and hear natural radio signals below 10khz using a small 1m long active antenna E probe (homemade)
