Dr All,
    pse excuse that yes= terday evening I sent a mail without signature. It was not yet ready but su= ddenly 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-Ger=E4t Nr.2" named "Frequenz-Eichpu= nkt-Geber."
    Two tubes 6K7 (VT86= ) and 6SN7, 100kHz multivibrator, wire antenna was necessary.
And it was built into an aluminum brea= d box with power supply.
A small part of the Droitwich history.=
