Repeater101 Note: There are exceptions to the above so check local repeater listings. Why do Repeaters use an Offset? To use a repeater a user station must use a different transmit frequency than receive frequency. This is a form of duplex, or two frequency operation.It is known as half duplex as you do not receive and transmit at the same time but normally use the push to talk button on your microphone ...

QEXfiles American Radio Relay League The American Radio Relay League (ARRL) is the national association for amateur radio, connecting hams around the U.S. with news, information and resources. PRC 104 HF Receiver Transmitter DC Power Using a BK Precision 1786 lab power supply, on receive the PRC 104 draws 0.16 Amps and on transmit the current varies a lot with voice peaks, maybe 1.6 Amps average, but the peaks might go up to 3 Amps or more. Valve amplifier A valve amplifier or tube amplifier is a type of electronic amplifier that uses vacuum tubes to increase the amplitude or power of a signal.Low to medium power valve amplifiers for frequencies below the microwaves were largely replaced by solid state amplifiers during the 1960s and 1970s. Valve amplifiers can be used for applications such as guitar amplifiers, satellite transponders such as ... o Funcionan las Cosas profisica.cl Fig. 2: Radio "de bolsillo" R 212 AM FM Receiver de bandas 530 1600 kHz en AM y 88 108 MHz en FM.
