LA1800 FM Radio  - 3V superheterodyne FM receiver (08/08/08)
Linear FM 30Watt  - ….(circuit design added 08/08)
Linear FM 50Watt with BLY90 - A amplifier of force RF for the FM, is always essential for the amateur that wants it strengthens some small transmitter, that likely already it has manufactured or has been supplied ready. The present circuit can give 50-60W RF force of expense, with control smaller than 15-20W in the region of frequencies of FM, that is to say in the 88-108MHZ. Transistor that we selected for ....(electronic design added 6/07)
Low Pass Filter For FM 88-108 MHz - Filter used for eliminate unwanted harmonic frequency at second and third. Notch filter, Band Pass Filter (BPF), and High Pass Filter (HPF) sometime combined in constructing LPF design. Schematic below for FM Broadcast Lowpass Filter 88-108 MHz….(added 08/08/08)
Low Power FM Transmitter - Useful to retransmit the hi-fi to another FM receiver nearby, or as a wireless mic  (schematic / circuit design added 9/02)
MC145170 PLL FM Transmitter - In order to simplify the transmitter design, we've used the new pll circuit from Motorola :the MC145170. This PLL includes the prescaler and a serial standard bus called SPI. (circuit added 04/05/06)
Micro Spy with FETs - (Tony van Roon's schematic / circuit added 10/02)
Micro Spy with TTL - (Tony van Roon's schematic / circuit added 10/02)
Micro Spy with Usw - (Tony van Roon's schematic / circuit added 10/02)
Micropower FM BroADCasting Circuits - (schematic / circuit design added 9/02)
Minature FM Transmitter - This miniature transmitter is easy to construct and it's transmissions can be picked up on any standard FM radio.  It has a range of up to 1/4-mile (Tony van Roon's 400 meters) or more, depending on the line-of-sight, obstructions by large buildings,etc.  It is great for room monitoring, baby listening, nature research,....(Tony van Roon's electronic design added 02/03/04)
Mini Tracker - Lets you find things, using an FM radio to pick up the beeps….(added 04/07)
Miniature FM Radio Receiver using TDA7088 - The electronic diagram of the monophonic FM receiver made with TDA7088T is shown on Pic.4.12. If built with SMD components it can be placed in a matchbox, altogether with two button-type batteries. The operating principle of this device is given in the ....  (added 11/05)
Miniature FM Spy Mic - This spy mic works from single 1.5 volts AA type battery cell. It is highly sensitive and has a range of 300 meters. You can use any HF transistor with cut-off freq. >300 MHz for Q. Use electret mic.  (added 11/05)
Miniature FM Transmitter - (circuit / schematic added 5/03)
Miniature FM Transmitter #1 - This miniature transmitter is easy to construct and it's transmissions can be picked up on any standard FM radio.  It has a range of up to 1/4-mile (400 meters) or more, depending on the line-of-sight, obstructions by large buildings, etc.  It is great for room monitoring, baby listening, nature research, etc.....(Tony van Roon's circuits added 08/09)
Miniature FM Transmitter #3 - (Tony van Roon's electronic schematic / circuit added 4/02)
