Well the XTBM has been used in many tests the last few days.
I was curious what the output voltage and signal frequency of both X10 and Insteon in X10 mode was sending.
My Insteon tends to be lower in output voltage and higher in signal frequency. Insteon is 131.65KHz X10 is 120KHz. The X10 mode of Insteon is between 123KHz and 124KHz.
The XTBM did find a BAD 2414U Insteon Controller. While testing it.
The XTBM said High Noise and showed no X10 data.
X10 monitors and modules also did not respond to the signals.
ELK ESM1 showed maybe five bars of signal but again no Green LED X10 Good Signal response.
I got a scope out and comparing a good one to the defective one. There are extra signal bursts at the incorrect timing. Guess it looks like high noise to the XTBM.
I have called it failed and out of warranty. Paperweight.
I also noticed a drop from 9.99 Volts [could be higher as 9.99 is max] to 3.67 volts on one tested outlet.
I had connected an IBM Laptop charger and it was the culprit.
