Easy 2 Meter Transmitter - This project is a simple transmitter using only one crystal and will cover 145.00 to 146.00 MHz. The crystal is a 44.9333 MHz crystal for 145.500 receive, as used in the Trio (Kenwood) 2200, PYE, Motorola, Tait equipment, to name but four. The frequency of the crystal is not critical as almost any other Xtal for the 2-meter band will function (added 8/03)
Filter simplifies software defined radio - 12/03/07 EDN-Design Ideas:  A Linear Technology LTC1992 filter replaces four op amps in the signal chain of a software-defined radio. 
Four Transistor Tracking Transmitter - (Tony van Roon's electronic design added 9/02)
HAM Radio BFO - circuit diagram of beat frequency oscillator using BF494 and how to listen amateur radio communication on ordinary BC receiver. . (added 01/05)
Hear Amateurs on your FM Radio! - (electronic design / schematic added 2/05)

Hear Amateurs on your Shortwave Radio! receive SSB with ease - (design added 6/07)
LED RF Signal Meter - (circuit added 6/07)
Light Sensing RF Transmitter - (Tony van Roon's circuit design added 8/03)
Light Sensitive Alarm Circuit - The circuit detects a sudden shadow falling on the light-sensor and sounds the bleeper when this happens. The circuit will not respond to gradual changes in brightness to avoid false alarms. The bleeper sounds for only a short time to prevent the battery running flat. Normal lighting can be used, but the circuit will work best if a beam of light ….(design added 08/08)
Long Range FM Transmitters - (electronic circuit added 10/05)
Low Distorition RF FM Generation and Detection Using Hyper-Abrupt Tuning Diodes - (circuit added 6/07)
MicroPower FM BroADCasting Circuits - (electronic design added 9/02)
Multiband CW Transmitter - Circuit / schematic (added 02/05)
NanoMount Switches for Microwave Applications - (circuit added 6/07)
