NordMende UW 342 RF generator

The UW 342 is a VHF and UHF generator covering frequencies from 4 to 900 Mhz. It is also a “wobbler”, a sweep generator.

I don't yet know the complete valve line-up. What I have seen is:

• ECL82, probably as power supply regulator
• EZ81, rectifier (but there is also a selenium rectifier)
• EL86, maybe as modulator
• a double triode?
• one 7-pin valve
• two valves in the RF generator compartment
• ... maybe more

I bought this signal generator through on a radio flea market of the Rotterdam Radio Museum in 2005. I thought this would be a nice generator to test FM receivers. The front is a bit dull and the case is a bit scratched. But on the inside, it seems to be in perfect condition.

It has two 60 Ω coax outputs. It seems to have two oscillators. One of them covers a lot of bands from 4 Mhz to 900 MHz. There is a sweep control. Two other knobs I don't understand. On the front, there are also two pin plug receptacles, maybe these are the sweep output.

Now I need to find the documentation. Maybe I can find some help... And maybo someone has a spare tuning knob, as one of the tuning knobs is a bit broken.
