well after a long time i came back ... Nigel i visited your website... and i m seriuosly thinking to take some advices from you.. not only regarding electronics.. but for physical fitness as well
...
Anyway.... i wish to make a remote control based on radio waves... which would work within a circle of 1 Km... i have not selected a frequency yet.. but it would be in the range of 40 - 70 Mhz..... the remote control shall be for controlling of 8 devices (TURN ON - TURN OFF, MOMENATRY ON ).
I hope u would give some good ideas and help me to select the better type of data coding... i thought of DTMF b'caz its simple.
I like Nigel, but that does not mean that no one else could give his/her ideas....![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
