Circuit of 88-108 MHz FM RF Amplifier With RF 2SC1970 can radiate far enough. At the time of tuning you should use a 50 Ohm dummy load. For the input signal should be installed to regulate the VR level so as not to over-modulation (30-50mW).
Good morning sir, my name is David Linus I'm from Nigeria, I want to really appreciate ur effort for putiin up this circuit diagram on line for people like me I build it and it works perfect, But pls sir I want u to help me and sent me 150watt or 100watt rf amplifier circuit diagram that can be power with this ur1.3watt rf amplifier circuit, and let me no how much it will cost me so that I can pay u,tho is my e-mail: linusdavid50@gmail.com. Thanks for ur understand.
