Signal Generator type 47.
Need you clever gentlemen's help again. Picked up yesterday. Any info you have please. Looks like a magnetron to me. I am more used to general receivers. Picked up as an old signal generator. Front panel poor. Unside for age like new.
Thanks for any help, Derek. |

Re: sig gen type 47
Blowing up the front panel, I espy a knob labelled 'reflector'. This to me would suggest a klystron. A very interesting bit of kit!

Re: Signal Generator type 47.
Does look like a klystron in there. It's not my field of knowledge, but it does look to be of c.WW2 era and low-volume production- it may be of historical significance, there are some members here with particular interest in this field who could likely advise.

Re: Signal Generator type 47.
Indeed a very interesting unit.
It is designed to generate an RF output wavelength between 9.0 and 9.2cms, for testing H2S MkII radar receivers. It is described in the overall manual which I have as a 50MB PDF file, if you want the relevant part give me time to extract it. Don't be tempted to power it unless you have a source of 80v 1600Hz power! Andy |

Re: Signal Generator type 47.
The manual is available on-line here -
https://www.blunham.com/Radar/Signal...S-MkII-III.pdf Para. 816 onwards covers this Signal Generator. Andy |

Re: Signal Generator type 47.
If you don't want it I'd willingly buy it, but only if you could pack it and post it to Preston (obviously at my expense).
