14 MHz SSB 10mW Transceiver -  ....
144MHz 5W  power Amplifier -  (electronic circuit added 05/06/07)
144MHz receiver with IC MC3362 Motorola -  (electronic circuit added 05/06/07)
144MHz TX/ RX  control -  (electronic circuit added 05/06/07)
144MHz VCO with FM & audio compression -  (electronic circuit added 05/06/07)
23cm Wide-Band FM data transceiver for high-speed packet-radio -  (circuit added 04/05/06)
2N2222 40 Meter CW/DSB Tranceiver -  In spring of 1998, NorCal sponsored a contest to design and build a project using no ICs and 22 or fewer 2N2222s as the active semiconductor devices. I thought this was a really intriguing idea, so I set about to design my version....(electronic schematic / circuit added 4/02)
3.3V converter delivers 3W from Li-ion battery -  11/05/98 EDN-Design Ideas....Lithium-ion batteries are rapidly gaining popularity in portable applications because of their superior energy density, low self-discharge….Several circuits here, scroll to find this one.... [Design Idea by David Salerno, Unitrode Corp, Merrimack, NH]
3.3V Lithium Cell Supply Requires One Inductor -  08/05/99 EDN-Design Ideas....Because of  growing popularity of lithium-ion (Li-ion]batteries and 3.3V power supplies, portable-equipment designers must often create a 3.3V supply that a single Li-ion cell can power.... [Design Idea by Matt Schindler and Jay Scolio, Maxim Integrated Products, Sunnyvale, CA]

30M PSK31 Transceiver -  ....
49MHz Walkie Talkie -  Lots of people are requesting walkie-talkie and RF remote control schematics, so here is some. Building se circuits needs special equipment and expertise in RF circuits. If you are going to experiment with se circuits, please note that I did not build.... [Peter Jakab, Electrical Engineer, Engineer of Informatics]
5 Watt 80 Meter QRP CW Transceiver -  A great deal of interest has been generated by my previous design articles, so I decided to go to work on a full blown transceiver design. After several months of work, the ROSE-80 transceiver was born.  This transceiver is similar to other designs but contains some unique differences.  This design boasts the following features....)schematic added 8/03)
7MHz SSB Transceiver -  Circuit diagram and brief description of 7MHz SSB Transceiver for Hams. The circuit is designed around two numbers of MC1496. It can push around 80 Watts with IRF840 in  final. You can down load HTML version or  printer friendly word document. (added 6/06)
80 Meter, 5 Watt CW Transceiver -  A great deal of interest has been generated by my previous design articles, so I decided to go to work on a full blown transceiver design. After several months of work, the ROSE-80 transceiver was born.  This transceiver is similar to other designs but contains some unique differences.  This design boasts the following features....
