I have a DSS receiver that I run into a modulator and then can use the
Satellite all over the house as if it was cable. The problem is we need to extend the IR from the remote control. We are now using some RF units from RCA and while they worked well for a few years, over time they are drifting off frequency. It seems to me it would make more sense to build some sort of 'device' to send the IR signals over the coax and then pull it out at the receiver end. Anyone have any suggestion or experience with building such an animal? Joel AG4QC |

Joel,
There are a number of products on the market that do everything you want. They wirelessly rebroadcast the output of your set top box to other TV's, and also wirelessly send back the signals from the remote. I can't remember brand names off-hand, but do a search on "video sender" and you should get some good hits. Joe W3JDR "Joel" wrote in message t...

Thanks for the suggestion, but I already have a modulator that sends the
locals and the Satellite to all the TV's in the house. I just need to somehow get the inferred remote control signal back to the receiver. Considering I already have coax run to each TV, it would make sense to us that, piggy backed on the cable. I did a google search and found about what I need if I wanted to buy all the equipment.. Except I would rather build my own. Seems to me I could modulate a low frequency carrier or DC signal and send it back over the coax. "W3JDR" wrote in message ...

Joel,
Any RF signal you put onto the coax could be severely attenuated by any splitters that are in your distrubution network. Attenuation will range from a paltry 3.5 dB from splitter output-to-input, but could be as much as 40dB from output-to-output If you start out with a relatively strong transmitted signal and have a relatively sensitive receiver, I suppose it would work, but beware of higher than expected path losses. DC is probably out of the question because many splitters and other equipment present a DC short-circuit. You should consider a frequency of at least a few Mhz. Joe W3JDR "Joel" wrote in message t...

Anyone have any suggestion or experience with building such an animal? =============== Just for info : To watch TV and switch channels from a remote location in the house other then the location where the digital sat rx and another TV set are located , I have installed a piece of consumer electronics costing equiv US $ 150.- It comprises a 2.4 GHz tx at the digital sat rx site and an identically looking 2.4 GHz rx at the remote location . This link takes cares of picture and sound to be carried to the remote location. In addition ,the enclosure of the above 2.4 GHz rx accomodates a 433 MHz LPD (low power device) link tx receiving its input from an infrared handheld device at the remote location. The enclosure of the 2.4GHz tx accommodates the 433 MHz LPD link rx ,its output being fed to a separate infra red output device which is fitted in such a way that it can be seen by the infrared receptor of the digital sat rx. This facility makes it possible to select any digital sat rx channel from the remote location . The infra red handheld device at the remote location can also control the audio volume of the TV set at the remote location through this TV set's own built-in infra red receptor. Hence there are NO cables (coax or otherwise) required between the 2 sites I imagine this type of kit is also available from outlets in the USA like Ratshack. In Europe (CEPT countries) the 433 MHz LPD band is used for various unlicensed devices including car key fobs. Note : If the above remote TV set is installed in a kitchen equipped with a microwave oven ,the oven when switched on would cause interference to the 2.4GHz picture/audio link (although only the picture will likely be affected).
