[sdiy] Wireless stuff

[David Anderson]

Hi Karl,

A couple of thoughts:

- In many countries, the radio spectrum is pretty tightly regulated. In 
the US, running an unlicensed transmitter is a good way to get a visit 
from the FCC. Depends largely on the frequency.

- quality wireless audio is actually quite a challenge. The wireless 
sets available are expensive because, even at the entry level, it's a 
decidedly non-trivial project.

That said, if you really want to dive in, the ARRL Handbook is a good 
reference.

> Hi list. I was wondering if anyone's done wireless audio and how to cheaply make it? It seems to me it shouldn't be very hard or expensive to do wireless receivers / transmitters for audio - but i'm not really sure where to start as i've never dealt with this kinda stuff before. For simplicity's sake if transmitting audio it seems to me that sending and receiving analog signals would be a hell of a lot easier then doing it digitally. Also, i'm wondering how many separate channels one could do this on - the FM band seems like a bad idea since there's potential collisions with local radio... any clues? I just thought that the wireless receiver/transmitters out there seems really bulky for what they do and also very costly, i get a feeling one should be able to DIY this for not that much money. Dreaming of never buying another snake cable ever again....
