In any gadgets with music I prefer using the ones with fm transmitters, because it is always good to hear brand new hit musics not only from the ones you have downloaded but also you will not be bored to hear the same thing again shuffling from your gadgets.

I like this wireless transmission idea! I was thinking, why couldn't you simply use this circuit http://www.grynx.com/projects/simple-skype-voip-analog-adapter/ attatched to the modem and a teminal program. This gives you control over baud rate and you don't need to write any fancy programs.

You could also record the output of this circuit to a cassette and play it back to the computer to have an ultra secure way of storing data! (who uses tapes anymore?, who would even check?)

Just my thoughts...

Anyone wanna explain to the dummy what exactly this does? Transmit data between 2 computers using radio waves?

As VA3TSK mentioned, coupling soundcards to FM transmitters is already very common. I have done it multiple times, although the power and frequency are a little higher than the transmitter mentioned in the article. I have also built a couple tiny-trackers that connect to a GPS on one side and a radio on the other that transmit location of the unit (including my car – kc8ufv-14) on the (US/CA) standard frequency of 144.39MHz

The first thing I thought of was sending NEMA data from my GPS unit (serial out) over GMRS radio’s and then decoding it on a PC. Would make a great tracking system for rocketry or UAV’s

Digital on FRS Family Radio? No, not legal. GMRS is another story…the answer there is Depends…Refer to the FCC rules. I beleive some digital is allowed.

BTW – If you really want to try this and use Linux, there are a dozen or so good sofware packages (generally available for most distros) that are free and do a lot more than just AFSK…RTTY, CW, Hellschriber, etc. Google hamradio software for linux and take your pick.

How about a nice retro radio-teletype or RTTY “rf-modem”? Hook the output up to an old Daisywheel printer, and you are set.

if anybodys interested on the eeepc front, a friends pointed me in the direction of this:

looks pretty good for getting wireless/wired LAN stuff working easily.

Sound cards are now the de-facto way to implement digital modes in Amateur Radio. See for instance http://www.kc2rlm.info/soundcardpacket/ or Google 'PSK31'. Any of these programs could easily be used with a low-power iPod-style transmitter.

Of course it's not really _that_ hard to get your Amateur license these days. See http://www.rac.ca/regulatory/arast.htm or http://www.hello-radio.org/whatis.html

I've used it to send text between two PC's via audio cable. supposedly it can send video with FM transmitters, but I've not gotten it to work yet.

Would also be cool to get something like that to work over on the voice channels of a cell phone.

Neat, now can you hook up a family radio and transmit data? The old ones I have have about a mile range. Is it legal?
