It would be cool to make one with more channels for analyzing the
quality of your amateur radio transmissions.. Something to think about
for another day. :) My Swan 500c puts spurious emissions all over the
place. I probably don't want to know what they look like. :S

Ascending and descending orange glow tubes, why wouldn't it sell! I'd
probably tinker with one...;-) Why only 7 channels? May I ask what
frequency ranges you decided to sample?

Pretty neat. As an audiophile toy, I suspect that it would sell
well. Something to put on top of that all-tube amplifier.

Hello everyone,
I am thinking of selling a IN-13 spectrum analyzer, either fully
assembled or in kit form. I've just ordered the preliminary
boards to get the final prototype together, but it would be 7
bands with a 3.5mm jack input. 12v input from wall power, and
possibly a mini USB port. The final product would be around 3.5
inches long and 1.3 inches tall, with the tubes going up from the
front. Below is a render of the enclosure to give you an idea of
how it might look. I'm still deciding on whether or not to leave
the sides open. Let me know what you guys think and if there is
enough of a market I will produce some.
Thanks!
Dan
