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?
===============
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).
