Care of your IRF-510 MOSFET's MOSFETs are susceptible to electrostatic discharge damage (ESD). It is important to use proper grounding techniques while handling the amp circuit board and the MOSFETs in particular. While working with MOSFETs you should wear a grounding strap and have an antistatic ma...

This is the most frequent question, and many newbies want a simple answer. There is no simple answer. The distance at which your signal can be heard will vary from listener to listener, depending on their equipment and location. In fact, many elements affect your range: * the transmitter power * the...

Using a series transistor as a class-A modulator works well in some respects eg excellent frequency response, but if you halve the standing voltage to the final to 6 volts and do nothing else, the output power will drop to a quarter. If you re-design the output match to produce the original power le...

IRF510 MOSFET
For a 5-15 watt transmitter, the IRF510 is a pretty good choice. Its Drain-source breakdown voltage is 100V, which gives a reasonable amount of headroom. On mod peaks the supply voltage will be 24V , assuming a 12V power source. The RF voltage on the FET will be something more than 2 times that, say...

Garifuna culture is getting more respect and understanding, as Belize radio stations and clubs play punta rock, a blend of Garifuna lyrics and calypso-style rhythms. Punta is an invention of the 1980s, but its origin goes back to the call-and-response pattern of earlier African music and to the dail...
