Ameritron ATP-102 Deluxe Amplifier Tuning Pulser
Person bought this and decided he didn’t need it.
Ameritron ATP-102 Deluxe Amplifier Tuning Pulsers relieve temperature-related stress on amplifiers, tuners, and dummy loads, while allowing tuning for proper system adjustments. They allow tuning an amplifier with full required drive from the transceiver without over-heating the finals or anything else in the RF line.
They send a series of pulses to the transceiver, allowing the peak power to be high enough to drive the amplifier to full power, but with the average power being low enough not to overheat the finals. Ameritron ATP-102 Deluxe Amplifier Tuning Pulsers work with any solid-state amateur transceiver or transmitter and all other equipment using positive keying line voltages below 50 V open circuit and 100 mA closed key current.
These pulsers use a 555 timer IC driving an FET open-drain switch. Two front panel controls allow for the independent adjustment of both repetition rate (pulse rate) and on-to-off time (duty cycle). Pulse rate is adjustable from about 17 to 40 pulses per second, while duty cycle is adjustable from about 10 to 90 percent. The keying time intervals are typically adjustable from 2-40 mS TX ON time, and a 24 to 60 mS pulse repetition time interval (pause)
