Hopefully X10 reads these forum inputs. I know that several others have reported RF receive issues with the new security console so I'm just reporting again as confirmation. I bought the newer configuration for my primary home and found multiple issues with connectivity to the sensors as well as overall stability. All were corrected be fitting an external antenna to the SC1200/SC-12A Console. The area being covered was no more than 1200 sq ft. I can't believe that the company is not expending excess technical support, dealing with high percentage returns, etc. In my case I added a simple telescoping antenna connected to the existing antenna wire. The antenna was mechanically mounted to a stand-off so it is in the wall behind the console where I had to route all the power/phone/discreet wires anyway. I used a 36" antenna which is a full wave length although I believe a half wave length would be sufficient. This would be a very easy modification on the company floor and provides a superior product comparable with the competition. The RF connectivity issue was also well known with the CM15A computer interface and again many in this forum ventured in their own modifications. But the company did not catch on. Security systems as well as home automation setups need to be stable with sound response to commands/status. Increasing the RF reception obtains it. Greg Miller
