DISCONTINUED Ameritron ATP-100 - Tuning pulser for amplifiers

The Ameritron ATP-100 Amplifier Saver lets you safely tune up your linear amplifier perfectly for full power output and best linearity. It protects your expensive amplifier from overheating, tube damage, power supply stress and arc-over during tune-up. It prevents premature failure and costly component replacements.

Ameritrons innovative pulse tuning technology lets you tune your amplifier at full peak output power for best linearity. It keeps average power to a low safe level to prevent overheating and power supply stress. "Why cant I just tune up at low power to reduce overheating and component stress?" you ask yourself. Well you can. but if you dont re-tune at high power (which causes overheating) you can create severe splatter and abuse your rube grids because of excessive grid current.

If your linear uses tubes that are easily damaged by normal tune-up, the ATP-100 could extend tube life. "Sniff out" RFI or TVI caused by rusty guy-wires, rain gutters, clotheslines and others by generating full peak power without amplifier damage. Also use to evaluate wattmeters and QSK systems. Set and forget internal trim pots let you tailor duty cycle and pulse rate precisely for your rig and amplifier. Plugs into your rigs CW key jack. Simply press Pulse Tune button and tune your amplifier normally for maximum power output.

Locking Pulse Tune and momentary Carrier Tune buttons. Fully shielded all metal case, 3 ¼" x 1 ¼" x 4". Uses 9 volt battery.
