Perhaps I missundrstood your earlier response, but I thought you had
questioned my comment on using a module with a RSSI output.  I just gave
this as an example that there are inexpensive modules with a true RSSI
output.  I did not propose using this particular receiver for the X10
sniffer application.  Even if it was tunable, its narrow bandwidth would
still make it unsuitable for a sniffer.

Since I had an application that did need a good RSSI to maintain a table of
access point signal strengths, I wondered if it is possible to get similar
information from the received analog output.  Wouldn't that be dependent on
the data pattern itself?

I'm sure your method will work fine to locate a stuck transmit button.
