FROGTRONICS

 

THIS IS THE PLACE IF:

  you are crazy about RF

  you want to build RF transmitters and  simple test gear

  you need some ideas when designing your own projects

You will find here a large collection of transmitters, large and small which I have collected for many years from various public sources. Some of these are also of my own design. There are also a lot of very good sites on the net to satisfy your appetite!

Unless otherwise stated, the transmitters presented work in the frequency range of about 80MHz to 110MHz which is the radio broadcast FM frequencies. The use of RF transmitters is very often restricted and it is your responsibility to check the rules and regulations which apply in your respective country. I will not be held responsible as to the use or miss-use of these projects.

Enjoy!
