The output of the IC-9700 on 23 centimeters is only about 10 watts. While this power level might be suitable for local repeater access, it is insuficient for weak signal digital communications. I therefore acquired this Down East Microwave/Q5 Signal 60 watt amplifier to boost the output power a bit. I drive the amplifier with approximately 2 watts from the IC-9700 to achieve the 60 watts output. The 2MLDPA amplifier is powered by my 13.8 volt, 35 amp Astron power supply.
