Recent experience makes me think that breadboarding is not a good method for any rf circuit. I built an IF stage on a breadboard which I had designed and built in 1991. Back then it worked fine. This time it got a gain of only 6 volts per volt on the breadboard. I built it on etched copper clad and got a gain of 72! Which is what it should have been in the first place.
This makes me think that for rf, anyway, a design on paper should be at least dead-bugged on copper clad board before making any conclusions about its merits or demerits. Breadboards are unreliable. Any thoughts?
