I just finished building one of my "projects". This is a device that will allow me to simultaneously view electrical waveforms, take voltage and dB measurements and actually listen to the differences in the filtering action of various PC's and PLC's.
I will now be able to actually chart and compare the filtration action and the susceptability to RFI of these devices using lab grade calibrated test equipment using one point of reference. As such, i may be able to present some type of "scientific evidence" that PLC's and PC's do make MEASURABLE and AUDIBLE differences. That is, when i finally get around to doing such tests. Please don't hold your breath though, as i'm pretty slow when it comes to this type of stuff. Just ask Ernie aka Subaruguru. He knows how long ago i started working on this device and it has been quite some time : )
Not only will this allow me to "weed out" PLC's and PC's that do nothing or are of limited use, i can further refine the designs that i and a few others had been working on. Quite honestly, i expect some "highly respected" AND "highly priced" products to fall on their faces. I've seen more than a few PC's that i already know to be nothing more than fancy heavy duty appliance cords with "high tech" connectors installed on them. I've also had one specific make / model of PLC that INCREASED the noise level when put into a system. As such, it is obvious that some of these are nothing more than over-priced, under-designed pieces of marketing hype while others do actually perform as claimed. As such, the results should be pretty interesting to say the least. Sean
