I want to learn a little to use a regular handy as a data radio. My idea is use 2 regular handy to send small packets of data from apartment A to house B using 2 computers at first. I heard that is called packed radio, am I right? I don't need to send big data, only a few bits and time is not critical, I need to send data in 20 seconds or less and the example would be: 10101010 10101010 (16 bits). House and apartment are 2 blocks apart (less than 200 meters). It would be great if radio could work in ad-hoc (as a network, and repeat if the third radio is out of range - This is for future expansion of the system). I almost forget I live in Argentina, so dollar is really high here, so please don't suggest me equipment too expensive. My budget can go up to a "Handy Baofeng Uv-5r Uhf Vhf" not more than that, as I need 2. I appologyze if my questions are dumb or I am completely wrong, but I couldn't find any newbie tutorial about radios and packet radio. Thanks so much in advance.
