Arduino Tuning 433mhz/315mhz Tx Rx Pair Range Extended
TUNING RX TX PAIR: Upload a constantly Transmitting code to arduino using RC-Switch library Tx Code Hook up tx to arduino, power it 5v from arduino. Have a 3 inch min antenna on tx. Remove rx antenna and hook up in another portable battery with arduino having same RX code from the Library. Modify the code to light up 13 no pin led on arduino when any valid signal comes. Now move 3 meters away from Tx, Open up the Rx Loose Wire Coil windings like 2mm each. Take a screwdriver for the Rx fix winding inductor and loosen the screw tiny step at a time. Go far if ur Led Blinks. By moving the inductor screw, you can adjust best settings. NOW AFTER YOU GOT FAREST PLACE IT WORKS, Attach a 3 inch long Antenna Wire to Rx and move far most it works and adjust. THIS IS THE PROCEDURE I FOLLOWED TO TUNE MY PAIR. By using 12v Tx range goes Top Best. BTW The Rc Switch Library worked with 8mhz attiny85 tx + 16mhz 328p Rx from 3 rd floor to ground. Just adju...
