Wavemeter Class D No.1 MK2

Post by davegsm82 » Wed Aug 22, 2012 9:18 am

Bought this at a car boot sale this morning, in very nice condition, no headphones unfortunately, I know little about it other than the basic info I've gleaned from the internet.

Could anyone share any information on it? Its uses, when, where etc?

Thanks, Dave.

Nice little find there Dave, I can't help as I know nothing about this type of equipment. I bet Rob does (Glowing Anode)

What bootfair was this? Cramlington by any chance?

It's basically a calibrated "crystal radio" to measure frequency. ie wavelengths, hence wave meter. It may have an audio or RF amp or both, hence like a calibrated TRF.

Not much to add really, good link here; http://www.royalsignals.org.uk/photos/classDno1.htm
The usual function of a wavemeter is to ensure you are transmitting on the fundamental frequency, rather than a ahrmonic.

Chris, yes you're certainly right, cramlington boot sale early AM. Before the hoards arrive 8)

Michael, that's the sort of simple reply I was looking for! So, with an antenna it will technically be a crude sort of receiver?

Rob, I'd not seen that page, thanks.

I've noticed mine has a Belling-Lee socket at the top right, looks like it has been modified at some point.

Dave.

Since it's mainly for checking transmitters it might not be very sensitive. But you can try with 20m of washing line :)
