I just received this unit. This thing has some weight to it, it doesn't feel cheep.
Running some simple tests thus far the most noticeable nice feature is the quiet relay.
Authinx has reduced the loud clicking relay sound we grew to hate.
Testing this with the XTB Pro I see just how much of a difference the new internals make.
This unit appears to max out the XTBM signal strength read out of 9.99.
I know the signal strength is above this as a repeater returns the same strength.
Tests with other transmitters show a 0.04 to 0.08 strength difference using a repeater so it is obviously sending a stronger signal then the XTBM reports.
This unit hasn't changed in appearance so it is good they gave it a new model #.
This sees even my weakest remote
Bottom Line:
This thing is
Just Awesome!It is a Power house!The only X10 transmitter that matches this kind of signal strength (that I have) is the new Wi-Fi module I'm testing.
You should have no problems with PLC signals not making it to their destinations using this.
