Radio-Amateur

[Vedran1]

Hello!

I want to know as much as possible about amateur radios, packet radio, antennas and more (tutorials, shematics, articles).... What is needed to start with radio communications (except license i know how to get that)?

It wold be great that most Electronics-Lab members in Europe has radios so they can contact that way

Thanks in advance for your answers!


Bye ;D

... i would also want to know about mobile radio stations like long distance walkie-talkies (for about 3km or something like that).

Thanks! ;D

try this simple FM transmitter that could transmit at a max distance of 50m with only 3v supply

Thanks Keile, but i already have one similar to that one...
I would like something of higher range so i can communicate with my friend who is 3km air distance far from my home.
If you can find something like that it would be cool!

Thanks! ;D

i have a transmitter called the big ear and its microphone is in a speaker horn and this enables it to pick up sounds even talking from a good distance and it transmits what it hears realy good sometimes nice and clear, to a radio headset so you can listen in on people and burgulars etc etc

 

[Vedran1]

steven have you got shematics for "big ear"?
