I've always wanted to get an XTB-IIR, however, it's always looked a bit
rich for me, even thought I've heard very good things about it. I had an
XPCR in my old house, which was a more urban location. The unit worked
poor at best. It sent all kinds of random X10 signals, apparently
triggered by line noise. I tried 2 units and finally gave up. Here, in a
very rural environment, it works well for the most part.  But, I have
seen some really weird, unexplainable problems. My question is, did you
get the kit or the fully assembled unit? Also, in the XTB-IIB
literature, it mentions that it might not play well with the 1132 due to
amplifying line noise.
Link: http://jvde.us/xtb/XTB-IIR_description.htm ... here's the quote:
"Both the XTB-II, and the XTB-IIR include a bandpass amplifier for X10
return signals. The XTB-II used the cost-effective workhorse LM318 for
that amplifier, but the XTB-IIR uses a significantly more expensive
Analog Devices AD817 to obtain the best possible performance. In
addition, the XTB-IIR includes a gain switch to allow it to receive very
weak signals in a relatively noise-free environment, while providing the
ability to recover stronger X10 levels in the presence of high
background noise. The bandpass filter will attenuate out-of-band noise,
but line transients can still make it through, and are amplified.
Devices sensitive to noise, such as the PowerLinc 1132, may not work
well with any of the XTB units."

Is this not a problem?
Thanks again ... maybe we can get this group going again ... there was
always a lot of good info when it was active.
