JC,
Regarding your testing you've done, specifically the 30 gallon fishy tank, what kind of fish were used during the test? Did you try electric eels? Could present a problem...
I have the 8 channel module and receiver now, but I won't have time for a few weeks to try installing it. [:@] If all goes well, I'll get the 14 channel module/receiver. I'm glad you guys are having success. [8D]
