Some pages on my website show X-10 signals using the Scope-Test2. While it
may, itself filter out higher frequencies, it will show the actual X-10
bits. However, it's best used with a scope that can capture and store the
signal - it's impossible to analyze things in realtime.

I'd suggest the 0.1µF cap and 100-ohm resistor as earlier suggested by Dan
Lanciani and myself (the Microchip appnote I cited uses this).
