There is a new function on our website!

We have relabeled the menu item "Schematics" to "Schematics / further documents".

You will find there not only the link to the circuit diagram servers of the NVHR as before.

From now on there is also an new link to a directory of all digitized documents in the GFGF archive.

Just have a look, test it and give hints and critics too to the webmaster.

Thx and kind regards from the webmaster!


GFGF-volume 10 (re)issued: A short history of radio communication receivers in functional diagrams

This proven standard work gives an insight into the long technical development path of radio communication receivers for commercial radio services as well as the amateur radio service over the period from 1929 to 1983, i.e. from the age of electron tube technology up to the first assured phase of proof of semiconductor technology.

The authors have handled worldwide radio communications within the framework of amateur radio over three decades, have become acquainted with the often extreme requirements that communication receivers should be able to cope with, and have analysed more than 70 radio receivers or receiver parts of transceivers in the process.
