Not sure it's useful info, but when I try this against the W800, I get mixed results. I can only jam other signals
if I hold the palm pad right next to the other transmitter. At a distance of about 5 ft away from the jammer, I
can pick up a complete signal from any other transmitter. Of course my W800 software will trigger an event on
the first complete (validated) x10 message-burst that matches a list of known codes. Second, third, forth burst are optional and
constitue and unknown x10 device (recorded for later review) if compliment checks are valid with repeats within a 700ms window.
I know not checking for repeats leave me open for stray signals, but two years and I have yet to record a stray signal that
matches my list of 300 or so learned codes. It also allows me to cut the response time to valid signal down
to N x (the number of skipped duplicates). It's all configurable, should I have issues in the future, I can adjust to make
certain signal burst match N times before being valid.
I took a slight trade off for response time vs certainty, and it has paid off in this particular case.
