Default Homebrew comms receiver

I obtained this receiver at a radio rally last Sunday. From the outside it looks like an Eddystone, but its definitely homebrew inside. What makes it unusual is it uses a rotating drum turret type mechanism for the rf coils.

Can anyone with a long memory ever remember seeing anything like this as a constructional article in magazines from yesteryear? I don't think I've ever seen a rotating drum mechanism in a homebrew rx before.

Cheers

Yes, I saw this on Sunday too and noted the Eddystone finger panel. It certainly did not occur to me it was a homebrew though.

I even thought Marconi Marine.

Looks like an ex-command series IFT in there too, with the black knurled top-knot.

That dial speaks to me as maybe Geloso?

Hi Andy,

In my misspent younger days, I bought 2 scrap Gothic Seafarer
marine receivers from a junk shop. They had turret tuners and I was
able to make up one which worked, and I implanted it into a WS19
in place of the PA capacitor.

It's not often you see a WS19 general coverage receiver. Sadly-
long gone.

Happy days.

Kind regards
Dave

I have a very vague recollection of a magazine construction project using a turret tuner but can't quite put my finger on which magazine it was.

Radio Constructor maybe?

Are you certain it's homebrew? The metalwork looks a bit too good, although it's possible the innards were built around a pre-existing chassis.

Hello everyone and thanks for the info.

Andrew, I'm pretty certain it's homebrew looking at the standard of the construction inside. The turret tuner is a bit rough and ready. It also utilises an external psu/speaker which was lethal and required remedial work before it could be powered up.

Thanks for the possible link to Radio Constructor Terry. I shall peruse the magazine indexes over the next few evenings.

Andy
