|Oscillator / Transmitter|
Output level can be raised by biasing the audio amplifier's output stage to a higher voltage.
|AM Oscillator for wireless headphone|
|High Frequency Source||Frequency source based on Saronix oscillator.|
|AM Transmitter||Transmission range 500kHz to 1600KHz.|
|Limiting amplifier forms AM modulator|
|Powerful AM Transmitter||Range of transmitter is 2 Km|
|AM/FM Simultaneous transmission||Based on digital IC 4001|
|AM DSB Transmitter for Hams||The effective output of the circuit is three times that of an equivalent AM transmitter.|
This circuit is designed to be used on receivers that use untuned wire antennas, such as inexpensive units and car radios.
|AM Loop Antenna||Uses the resonant properties of an inductor and a capacitor connected in parallel to receive weak AM stations.|
|Medium Wave active antenna||The circuit amplifys the input from a telescopic whip antenna.|
|RF Amplifier for external antenna|
|AM RF amp for internal antenna||AM Booster for clear reception.|
FM receiver with audio amplifier.
|40 meter Direct Conversion Receiver||One can listen to amateur radio QSO signals in CW as well as in SSB mode in the 40-metre band.|
|AM Receiver||Simple receiver with three NPN transistor|
|AM to FM Converter||The circuit helps to listen AM station on a FM radio.|
|AM receiver||Receives the AM signal at 118.250MHz the same frequency as used in aircraft communication.|
|Portable AM Receiver||this receiver covers the medium wave band band from approximately 550 to 1600 KHz|
