Transferring bits over FM ?

I will try to be brief.

I am just wondering where to post my question about creating small FM
transceiver and receiver (separate) which would send / receive a couple
bits of data.

Which newsgroup can help me?

Thanks

Likely this one would. Doing data on an FM link is actually fairly
simple. If the data rate is low, an existing radio and an FSK signal
is an easy way to go.

How long of a distance?

If you want to make life easy, just buy an RF data link from Sparkfun
Electronics (www.sparkfun.com) for about $14. I have used these.
They work great and are very simple to interface to. I'm assuming, of
course, that you aren't doing this to learn about RF circuit design.

BTW - If you're interested, I have a circuit design that uses 8-bit
shift registers and those RF data links to continuously transfer 8
discrete bits from one end (of the RF link) to the other. It's very
cool - turn on the bit at one end and it comes out the other very
quickly. Let me know. I could email the design to you.

Thanks for the link!
I want to learn, but first I want to try if the concept works.
(RF Link - 2400bps - 418MHz sounds great !)

Oh. If only I could design such things ... :(
I hope one day I will be able to be an electronics hobbyist like yourself.

Thanks for the information

P.S. Which group is better for this kind of interest?
sci.electronics.design or .misc?

Neither.

The most appropriate place is sci.electronics.basics

Read Mark Zenier's guide the sci.electronics.* hierarchy:
ftp://ftp.eskimo.com/u/m/mzenier/seguide9706.txt

INdeed, you should have done some work in the first place before
cross-posting this message.

How many are a "couple" How cast are they going to change?

for just a two or three that won't change often, I'd gate an audio
oscillator per bit, and use a tone detector at the other end.

For more than that, I'd serially send the bits over AFSK.

Thank you for the information (and the link).
I will look more carefully next time.
