Stuff that worked
« Reply #15 on: April 14, 2010, 10:53:21 PM »

Hey folks, just a quick update on RF issues that I've finally gotten over (though I make no claim that I thought this stuff up, just adapted it and went through much trial and error based on the INSANELY HELPFUL people on this forum!)
For controlling macros for motion sensors and cameras in my home, I ditched the CF19 that came with the camera kit.  I am using two CM-15A's with the "clip the end off and connect 38 inches of thing gauge wire to the end" modification.  RF went from reception of 10 feet with the stock antenna to outside in my garage with the antenna mod.  Still not entirely sure that both are receiving the RF though, since I think only the one plugged into the PC is getting RF signals from my DS10's through my Onalert plugin.  Who cares, it works!
I am using a TM751 transceiver set to the motion sensor house code (motion sensors and cams each have their own house code) with the CM 15A's set to not transceive the motion sensor code.
Also, I really wish I could remember who thought this up, but I was surfing so long today that it' all blurring together, so I apologize.  Someone mentioned that a way around interference from metal in the surroundings of a DS10 would be to relocate the unit itself and use some wire to dramatically extend the leads that the magnetic switches are attached to.  That saved my bacon.  I have sensors on my garage and service doors, both made of metal.  I used some old garage door opener sensor wire and ran the wire from my DS10 on the door all the way to the wall by the interior door, and it works.  Hot damn, I feel like this might actually work out in the end!
Again, thanks to all who post and offer their tips and advice.  It's paid off big time for me, and I hope things continue to go well on this end!

evadorev; Not all setups work as well as your setup seem to.
Wiring in many cases can be a problem. Even those with each room on one circuit or multiple circuits in one room.
Signal suckers; noise makers and phase issues can effect all types of wiring schemes.

I am glad yours seems to be fine.
