Hello All,

I wanted to inform everyone about a comprehensive introduction document to amateur VLF frequencies below 8300 Hz written by Bernd, DL3JMM, originally in German but translated to English by AI. This document talks about transmission and reception techniques and provides an excellent foundation to anyone interested and looking to get started working and receiving below 8300 Hz. Here is Bernd's message below:

Hello VLF (Community),

Various letters with inquiries prompted me to create a short description of radio operation at frequencies below 8300 Hz.

Here is an introduction:

1. General

The frequency range below 8300 Hz offers fascinating experiences in radio connections that only a few amateurs have made so far. Overcoming challenges that were initially thought to be insurmountable gives a „ Marconi feeling “ of the early days in radio. In the meantime, amateurs have achieved connections between Europe and Asia and between Europe and North America.

Here is the link to click on:

and he ensured the good translation into the English language.
