On yesterday's hamfest over in Rosmalen (NL) I obtained a rather interesting piece of kit. It calls itself Siemens Hilfssender. Or: auxiliary transmitter, built by Siemens of Germany.
It has a microwave tube, an adjustable cavity (from what I now know), it is built from silver plated brass, it weighs a ton and is testament to the proverbial Deutsche Grundlichkeit. I think it is for use around 2.4GHz (assuming I interpret the readout correctly that corresponds to the
tuning of the cavity).
I am really curious if one of the EEVbloggers has any clue what this puppy belongs to? I also wonder about it having only one RF connection? Oscillator? I cannot find a partnumber on the tube unfortunately.
