I'm not living in the UK but even if yes, the target range is so short it cannot disturb anyone.
So I need to build a montage that takes the 1V peak to peak HF signal and by impedance conversion produce a higher amplitude signal.
The input impedance of the system should be 100ohms, the output...
macgyvers2000, of course if the only solution is to buy a 433MHz kit, I will do it, but first I would like to make this self-made transmitter work.
VE1BLL, because of the relatively small amplitude of the carrier when it is ON, the radiated power if 100% efficiency is achieved will be only...
Hi all,
I'm building an RF remote control for a PC and have the following constraints:
-The maximum frequency my scope is able to view is 50MHz, so it sets the maximum frequency of the carrier. In my case it is 43MHz.
-The case is 8*10*3cm => the maximum size for the antenna is 10 cm (I...
Hi all,
I built a 29,5 MHz oscillator for RF carrier generation. When I connect a 5K resistor between ground and the output of the oscillator, amplitude is divided by 2. That means the output impedance is arround 5K.
I also built a 10 cm long antenna made of copper wire. I will use this...
