Simple, non-professional radio technology and QRP power!
That is what you will find here. There are some complex designs but many designs are simple radio amateur circuits. They will never be used professionally!
These simple circuits and rigs can give you much fun: home brewing, portable activities during holidays, etc.
Batteries and inverted V dipole antenna's with a fishing rod as the center support are all you need to make many QSO's.

QRP power!
Perhaps that you cannot believe that you can make many QSO's with low QRP transmit power of 1 watt. Indeed, some practice is needed in the beginning so do not give up too soon. Every boring standard QSO becomes an exciting experience with QRP power!

Simple Technology
Simple Technology can give you much fun, is cheap but not perfect...
There are disadvantages like VXO control instead of a VFO, direct conversion receivers that receive both sidebands and simple frequency displays that are not so easy to read. But working with such simple equipment is often more exciting than working with a much better commercial transceiver!

Experience that you can do much with QRP Power and Simple Technology but not everything!
However, Barefoot Technology and Barefoot QRP power is all you need to collect a shoe box with QSL cards and to become an enthousiast radio amateur!

Miguel is very active with home brewing and QRP.
He has a very nice home page that you certainly should visit!
We have almost the same call, only one character difference!
