Default DIY Spectrum Analyser

Here's an oddball - I discovered this in my loft. It's is absolutely something I will have made, but I don't remember what it is for!

The scanner and PSU boards are ones I recognise but I don't remember where from, but the RF bit is one I don't remember at all. It may be for the 35MHz or 459MHz model control bands....there's a 10MHz crystal on the RF board
