JP1 Remotes

(1) This device is a DIY (Do-it-yourself) project. I have NEVER seen anybody selling this detector;
(2) It may be a fun project to learn and decypher you fan's RF codes, but you aren't going to find a "universal" RF remote to send them. They simply do not exist. If you're thinking that a UEI remote with an RF extender can somehow be made to transmit one of these RF signals, you are mistaken. The "RF" of these UEI JP1 remotes is simply to encode the IR signal, send it over a greaater distance, and have it unencoded by a matching RF-receiver to IR-transmitter base station. The RF is just a "carrier" if you will for an IR signal.

I figure this thread has been dead for a while, however I have found a nice little RF transmitter/receiver pair that could probably be integrated to a lot of IR remotes to considerably increase range and/or interface to PCs. All that would be needed would be a lowpass filter to demodulate the IR LED's input and possibly a small dc-dc converter for the power supply.

(the transmitter is the smallest of the two boards)

Nobody tried this?

I haven't use those particular modules, but the UHF remote kit from and obsolete satellite TV system.

I literally sawed off the end of the remote from the kit, and set it up so the signal from a typical IR receiver module will gate it. The receiver module (and external box with an antenna), is connected in parallel with the IR receiver of the target device. In one of my satellite TV remotes, I installed the transmitter board.

I am very interested in the IR/RF reader device is there anywhere I can buy one assembled and tested?

Hmm, this thread seems kind of dead, but there is a tool which together with some very simple hardware can scan RF-codes and generate PRONTO-codes in real time on both Windows and Linux on http://wiki.nethome.nu/doku.php/analyzer/start. It uses the microphone input, so it requires no special hardware drivers.
