I picked this up at a rally today, at first because I thought the box looked useful, but now I'm intrigued by the board inside it too. It appears to have been hand-built from a kit many years ago.
The board has a "British Amateur Television Club" logo on it (under the large silver capacitor at the bottom left) and the text "BATC 70 cm TV TRANSMITTER". The crystal is marked 108.875 - does it transmit at 435.5MHz?
Does anyone recognise this? Are there any schematics or other info for this kit anywhere?
The heatsink on the transistor suggests that it has a "real" PA stage. If I ever decide to get a licence and get on the air, I think I could learn a lot from experimenting with it. I'd be reluctant to connect it to an antenna before I'm sure I understand how it works, though!
