سهل التجميع والعمل، على الرغم من أنه ليس بسرعة 70 ميلا هرتز، يمكنك ضبطه قليلا عن طريق نشر L1 والمدى 10 أمتار فقط أو نحو ذلك. لقد حفرت فتحة في الغطاء من أجل الهوائي.
Another neat little project board to play with for learning about electronics and radios. Quick and simple to build and a core of other projects and experiements. Two minor points to note: 1) The default frequency is about 80 MHz, not 70 MHz (I have built five of these so far and measured them with the GOOIT GY-560 50 MHz to 2,4 GHz Frequency counter.) 2) In the circuit diagram uses the wrong symbol for the inductor, L1. The symbol used is for a variable, iron cored inductor. Please see the attached picture. Still, 5/5 for this kit :)
I will be enjoying to make kit with my gound sun. I will recieve and talk useing my mobilephone.
Worked first time. Very easy to build and with good clear instructions, ideal for a beginner to electronic and radios. I bought three: One to build as is an the other two to experiment with.
Llegó rapido y economico, ideal para iniciación a la electronica.
With my 45 years of experience in electronics I tried this and sorry to say that it does not work
