Dr All,

    pse excuse that yesterday evening I sent a mail without signature. It was not yet ready but suddenly off and sent. Computers sometimes seem to have their own meaning.

Droitwich 200kHz was used by many hams as a frequency standard at that times. In DL-QTC 11/1954 page 474 one can find the "DARC-Standard-Gerät Nr.2" named "Frequenz-Eichpunkt-Geber."

    Two tubes 6K7 (VT86) and 6SN7, 100kHz multivibrator, wire antenna was necessary.

And it was built into an aluminum bread box with power supply.

A small part of the Droitwich history.
