Ameritron ATP-102 Amplifier Tuning Pulser II

Ameritron ATP-102 Amplifier Tuning Pulser II

Deluxe Amplifier Saver

This is the deluxe version of ATP-100. The ATP-102 has, in addition to the features listed below, Duty Cycle and Pulse Rate controls on front panel for easy performance testing of wattmeters, QSK systems and other equipment.

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

RBI-1 Amplifier Relay Buffer Interface

RBI-1 Amplifier Relay Buffer Interface

Put this little box between your radio's amplifier keying output and your amplifier "relay" input to completely isolate your radio from your amplifier.

Draws 0.3 ma from your radio keying circuit.


Will key ANY amplifier T/R relay up to 200 VAC at up to 3 amps!


Ground on "input" will provide closure on "output" connector.


RCA jacks in and out, 3 feet of wire for 12 vdc (total draw from your 9-15 VDC power supply is only 40 ma!)

High quality relay box to interface between any radio and will key any amplifier.
Many newer radios can only provide for a small amount of current on the external amplifier keying output.

When connecting your Radio and Amplifier, there may be switching voltage, polarity, and current incompatibility  that can cause damage to your radio or amplifier if connected without a switching interface between them. Even if your internal radio switching looks like it might be usable, it is wise to have an extra degree of isolation between your amplifier and radio with our relay buffer interface.
