Please log in for more thread options What hacks exist to allow other IR remotes to send RF to things like the base station Radio Shack uses on things like their 8-in-1 remotes (15-2117)? It'd be handy to be able to send signals through this base station and I'd be willing to hack up a remote or two to do it. I ask for several reasons, one is that RS has discontinued this product so it's hard to get spares. The other being it'd be nice to use some other gadets to push the signals (if at all possible). Alternatively I've got an X10 MouseRemote receiver if it's a matter of using something different RF-wise. Is it possible and who's got links? -Bill Kearney | |||||||||||||||||||||||||||||||||||||||||||||||||||||||

Please log in for more thread options all 418MHz signals as IR. The FCC ID number on the remote or base station can be used to verify that it uses 418MHz. If it does, the most recent versions of the Pronto and Marantz remotes and several models of the Home Theater Master remotes can send 418MHz RF. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||

The FCC ID on the remote is AA01502117. I'd search for it on fcc's site but it appears be offline (or too busy to answer). Hope your health is well and thanks again. -Bill Kearney | |||||||||||||||||||||||||||||||||||||||||||||||||||||||

The 4-pin RF transmitter modules shown at http://www.mbx-usa.com/modules.htm need +5V, GND & DATA. The IR signal is usually sufficient although range is less than optimal because the RF transmitter is operating at the IR carrier duty cycle. The transmitter turn on/off time is less than 1 µs and the pulses in a 40kHz IR carrier are ~12.5µs at 50% duty cycle. You can filter the carrier but that will usually reduce the amplitude and you'll need to amplify it to trigger the RF transmitter. The upper portion of the circuit shown at http://www.mbx-usa.com/ocelot2rf.htm will work for this. Most RF receivers will not turn off so fast so they will output the DATA signal w/o the 40kHz pulses. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||

Please log in for more thread options Curious, I also looked up the Hughes remote I have for a DirecTV receiver
( OZ5HNS1026824 ). Apparently it uses 418 Mhz, which is what the Pronto units use as well, isn't it? I wonder what sort of signal it's 'shark fin' antenna puts out? The schematic for which is: https://gullfoss2.fcc.gov/prod/oet/forms/blobs/retrieve.cgi?attachment_id=103912&native_or_pdf=pdf There are 18 (out of over 400) 418MHz devices from X10. With part numbers beginning with B4S. Don't know what they are. So it would seem the devices I've got are all on 430MHz. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||
