English description below

Need simple line-in / line-out audio wireless senders/receivers @ cd-quality. A nice setup would be to use any one of three transmitters and all of 3 receivers simultaneously. There are some good products out there (e.g. AudioPro WF100, Atlantic WA-50-SYS) but they are expensive. Anyone tried the Aurel TX/RX Audio 2.4 ? Even these are expensive at about €60/pair and I want 3 or 4 pairs!

Although wireless communication is nothing special these days, it is not a panacea. Below the ground, tor instance, radio waves will not get you very tar, In such cases, nothing beats copper wire to set up a reliable communication link. The communication system described here is remarkable because it uses only one such wire. Low-cost, and ideal tor a camping site intercom, or a cave explorers' talk line.

Today, Radio or Wireless as we used to call it, has beeome so much part of our lives that is difficult to appreciate the fact that in earlier days it was considered almost a miracle that Music and Voices could come into our hornes 'out of the air' by Wireless Waves.
