Tuning Pulser Tuning Pecker PKR-1
The CTR Engineering PKR-1 is a more modern version of the Ameritron ATP-100 and ATP-102 Ameritron tuning pulser. This device relieves temperature-related stress and lessens the chance of damaging arcs in amplifiers, tuners, and dummy loads while allowing safe adjustment for maximum linearity.

This device uses a pulse generator chip with adjustable rate and duty cycle. It is battery powered with a long-life garage door remote type 12V battery. The current draw is very low. Battery life will be years with normal use.

PKR-1 controls
The PKR-1 modern replacement for ATP100 and ATP102 Ameritron pulsers has front panel weight (duty cycle) and rate (speed) controls. The pulser should be adjusted for the slowest speed that allows stable meter deflection along with the shortest pulse width or weight (duty cycle) that makes full stable peak power from the radio.
It requires one simple connection to the radio via one supplied cord.
