MR26 Mods

The MR26 rf receiver from X10 proved to be quite susceptibleto noise in my home automation environment. This produced numerousfalse commands, which only increased with the addition of an externalantenna. What I did here was use a variety of approaches by othersto produce a unit which dramatically reduces the production of erroneous commandsand has a range much greater than its original configuration.Use the images in the left frame to see photos and descriptionsof the process.

• Jeff Lomicka - how to build a Mac adpater cable for the MR26- schematics for serial pins
• Denny Hayes - used Denny's idea to remount the MR26 inside a metal project box
• Thanks to Daniel Petitgrand for the wiring diagrams and suggesting the total isolation of the antenna through copper windings on the rf coil.
