So I wanted a mini remote to engage my x10 sprinkler setup from the yard but as you all know that ain't gonna happen with a KR22a's paltry range of what, 20 feet.
So I opened it up and found an oval trace that look a like a loop antenna.
I soldered 12" of insulated wirewrap wire to the loop and bringing it outside the remote, ran it around the outside of the remote 2 times then trapped the wire by snapping the cover back on.
I took it outside and it's range was increased but not enough to wander all around the yard and have it work. But!
It's hot enough now to work from the master bedroom and reach the tm751 in the dining room where before it was no way jose.
This allowed me to swipe my wifes KR19a which was leashed to her bedpost and works all over the yard while she uses the tricked out? KR22A.
