Hi.

This thread has inspired me to revisit the Simple Spectrum Analyser (G4PMK) circuit that I built back in 2007 (can't believe it was that long ago). I originally bought the kits of parts from JAB Electronics (JABDOG) but made my own PCBs, and completed the unit, but never got around to testing it as there was an impending house move so it was packed away in storage.

I really like the idea of having the spectrum analyser self contained with it's own display that Dave (ParcGwyn) has built. I'd be most interested to see the circuit details for the display unit. I have a half decent oscilloscope tube from a redundant Heathkit scope plus the power transformer etc so this could be achieved quite economically I think.
Dave, would you mind sharing the circuit of your set up to give me a few ideas how to go about the addition of the display?

Regards
Symon.
