RF Module

[dhouston]

Hello dhouston,
The file you posted (UR19A.PDF) has a nice transmitter schematic.
But, the complete details of L1 are not given.

L1 is a circuit board trace that acts as the antenna. If you're going to build something, build the one in the http://jap.hu/electronic/rf/el9805.pdf link.

Do you have a reciever schematic for this transmitter ???

X-10's RR501 used almost exactly the same circuit as the Ming receiver for which you found a schematic. Or, you can do a Google search on "RR501 Orysh schematic".

The RF1 transmitter and receivers shown on the site cited by ra68gi http://www.modielectronics.com/RFPG_1.htm are the ones made by Wen Shing (or are clones thereof) that I mentioned earlier. You cannot go wrong with them.

OOOPS! The RF modules in both links from ra68gi are from HiMark (Taiwan). X-10 now uses similar HiMark modules in their latest interface (CM15A). As I recall, HiMark has schematics and parts lists on their website.
