I found this link. Maybe you can check it out as they talk about starting a powerful FM radio station and a low cost alternative. http://www.prometheusradio.org/alt_startfm.shtml

Bluetooth is a technical industry standard that facilitates communication between wireless devices such as mobile phones, PDAs (personal digital assistants) and handheld computers, and wireless enabled laptop or desktop computers and peripherals. A single Bluetooth-enabled wireless device is capable of making phone calls, synchronizing data with desktop computers, sending and receiving faxes, and printing documents. For example, an individual can use a Bluetooth connection to print a document from his PDA. \n\nBluetooth devices use a microchip transceiver that operates on the 2.45GHz frequency and have a range of up to 10 meters (approximately 33 feet).

Hello.  KG2DI here! First, go to www.arrl.org the home page of the American Radio Relay League.  You can find many local radio clubs that offer classes - some take as little as one day - to help you get the entry level license, the Technician Class.  Or you can go buy "Now You're Talking" at Radio Shack for $21.95.  It's a book that'll get you that license if you can't go on the computer or if you aren't close enough to a radio club offering classes.\n\nHey, good luck!  It's not just a fun hobby but a valuable national resource as well.  Hams help out every time there's a natural or man-made disaster that disrupts normal communications.  We manned shelters in New York City after 9/11, we manned shelters and assisted the Red Cross, Salvation Army, FEMA and many other agencies in Louisiana and Mississippi following Hurricane Katrina - in some areas, for weeks!  Glad to see ya got an interest.  Go for it - you don't even need to learn Morse Code to get that entry-level license any more!

Here is a great link that describes the entire breakdown of piconets and modular bluetooth framing. Even has some great pix.\n\nhttp://www.wipo.int/cgi-pct/guest/getbykey5?KEY=01/30031.010426&ELEMENT_SET=DECL

bluetooth is a wireless standard used on may devices, like cell phone headsets and some electronic devices.\nit basically is a short area fm transmitter.

buy two wireless VOIP handsets and mail one to the place you wish to send to.\ninitiate an internet phone call.\nboth pick up handsets and walk away from the wired connection point.\n\nbingo!\n(also works with cellphones, particularly if you buy two pairs of duplexing walkie-talkies and duct tape one of each pair to a cellphone mid-call & walk away with the other)\n\nalternatively, negotiate with your local pirate radio station to borrow one of theirs in exchange for you not turning them over to the feds. the range will only be about ten miles tops, but 1/ that's more than pretty much anything you can buy in the store, 2/ you didn't specify exactly what you meant by "long range", 3/ you could probably reverse-engineer it pretty simply and plug in a higher power amp.\n\nremember that lower frequencies carry further but have progressively worse bandwidths. if a fair bit of noise can be tolerated, AM is also detectable over a longer distance. also remember that this sort of thing tends to require a license, particularly if you're messing with frequencies that may disrupt the business of other licensed users (commercial / national stations, emergency services, taxis, air traffic, maritime, HAM radio) and you could get a serious legal buttspanking if you cause any trouble and/or are discovered.\n\nPS - 1750 metres? isnt that like 171, maybe 172khz? slap in the lower third of the (inter-)national / commercial (only just, nowadays, but still hanging in) long-wave AM band? potentially dodgy that, doesnt the bbc world service, US overseas forces radio, some station like that already use 172khz? bbc radio 4 long-range is certainly on 198khz...

well,\n\nif you meant what technology should you be using, then i recommend using FM or Bluetooth; each have some pros and cons!\n\nFM is cheaper to implemet, but harder to implemet, bluetooth (lets say 2 serial bluetooth adapters) are more expensive but much much easier to implement... specially with digital signals!\n\nif you ccan edit or give more information about what you want maybe i can help you more!

Bluetooth is a wireless technology that enables any electrical device to wirelessly communicate in the 2.5 GHz ISM (license free) frequency band. It allows devices such as mobile phones, headsets, PDA's and portable computers to communicate and send data to each other without the need for wires or cables to link to devices together. It has been specifically designed as a low cost, low power, radio technology, which is particularly suited to the short range Personal Area Network (PAN) application.  (It is the design focus on low cost, low size and low power which distinguishes it from the IEEE 802.11 wireless LAN technology).

which ones? there are quite a few built in system ones then you can also make your own. are you looking for examples?
