Standard Telephones & Cables, STC R6
Hi
The Radio Museum has been sent photos of an STC R6 receiver. Going by the wavebands it looks like it is possibly an early Navy receiver from around 1935. The frequency ranges are; 1200 - 430kHz, 430 - 158kHz, 158 - 60kHz It has 8 valves 9D2 9D2 9D2 9D2 9D2 9D2 11D3 7D7 here are some photos. Any comments on its use, history or other information would be very helpful. Thanks Mike |

The 2 big tuning-drives look identical to those used on the Gee "RF" units of WWII-vintage.

Re: Standard Telephones & Cables, STC R6
The two big tuning drive are quite standard slow motion drives by Muirhead. Nice to see the bakelite outers aren't broken.
Common in late thirties and WWII stuff. David

Re: Standard Telephones & Cables, STC R6
The architecture is remarkably similar to the ST&C WWII-vintage BBC CS-8 100kW broadcast transmitter drive units, as shown here at OSE9, even down to the colour of the paint (yes, I know it's black and white...).
