DESCRIPTION This ZIP file contains information about building a small radio transmitter, which has a PCB 1.75 x 2.5 (45mm x 68 mm) and has a range of about 30 yards or so. The documentation with the circuit says the freq range is 100-108 MHz, but I h Posted at 10-05-12 by Sky views(51)
Diagram of the coil of enameled wire in 3.2mm by 1.0mm drill around 6-8 on the circle, can cover 88-108MHz, 7 laps around the 100MHz. The distance is not very far, 50 meters (open area)! Although not too far, but for beginners it is very helpful! Posted at 10-03-11 by Admin views(303)
