| 1962 | How severe can senility be? Just check out Slowman.
I use a nice little foxhunt sniffer made by VK3YNG which is remarkable for the incredible dynamic range in its front-end (quite a sensitive lo-noise receiver, but you can still DF when you're standing on 100W of RF transmitter, it doesn't swamp).
Anyhow, he found out the hard way that a commonly recommended decoupling method, namely a small cap closely paralleled with a larger one, often causes major problems when the small C resonates with the inductance of the larger one.
... just one case in point.
If anyone has an idea how to build a front-end like these have now that the dual-gate GaAs FET is unobtainium, I'd like to hear it.
Colman's mustard tins. I made an arc lamp out of one once.

Altoids, tobacco tins (I used to smoke a pipe ;-), all kinds of useful packaging out there.
