High voltage regulated power supply for RF amplifiers. This is an enhancement of the article by VE6AXW in July/Aug 1999 QEX. I have redrawn the schematic for clarity, added EMI filtering, included a programmable power on timer, and generated a printed circuit board layout. Works for most voltage values.

“In the pioneering sprit of amateur radio and open source hardware and software, I’ve assembled a collection of information and engineering plans for a variety of amateur radio projects. These projects cover a wide range of disciplines.” – KD7LMO

From the GNU radio web site

“GNU Radio is a collection of software that when combined with minimal hardware, allows the construction of radios where the actual waveforms transmitted and received are defined by software.

GNU Radio

What this means is that it turns the digital modulation schemes used in today’s high performance wireless devices into software problems.”

APRS TINY TRACKER USING PIC16F84A

Amateur radio projects that I built for myself and have PCBs & kits made available to other radio amateurs interested in building similar projects.

This PIC based LCD Temperature measurement project was planned to measure two Temperatures Simultaneously. It can be effectively used to measure your room temperature and may be used for measuring RF Amplifier Temp.

The American QRP Club

The American QRP Club was formed in June 2003, and later incorporated, as a organization of ham radio operating enthusiasts interested in low power operation – these types of hams are called QRPers. The AmQRP Club is not affiliated with any geographic area and its membership does not meet monthly as do many regional radio clubs. Instead, the AmQRP provides online information, instruction, goods and services to the general QRP population for educational and enjoyment purposes.
