Description
The Gemini 70-1K 432MHZ Linear Amplifier is a solid state 1000W CW output Linear Amplifier for 430-440Mhz.
ALL MODE OPERATION
Being a Linear Amplifier it is suitable for all modes of operation SSB/CW/RTTY/PSK/FT8 etc.
HIGH DUTY CYCLE
From the same stable as the Gemini 2-1.2K the Gemini 70-1K 432MHZ Linear Amplifier has been designed from the start with high duty cycle usage in mind. The core of the amplifier is dominated by a 7.5Kg aluminium heatsink cooled by three temperature controlled fans making it ideal for dedicated EME / MS / FSK / JT mode users and contesters.
WORLDWIDE MAINS OPERATION
The Integral Power Supply units will accept 100-260V Mains Input so the unit can be used worldwide without any modifications.
QUIET OPERATION
The Gemini 70-1K is quiet in operation. Main cooling fans only run when they need to and are controlled by our own PIC fan controller giving step-less speed control proportional to temperature.
