PTT & FAN Cable for SunSDR2 PRO/QRP

This cable connects to the EXT CTRL jack on the SunSDR2 PRO or SunSDR2 QRP and to an external amplifier or other device to let you control Transmit/Receive switching automatically from the transceiver.

The cable also have a 2.1/5.0 mm power plug for connection of an optional fan which is placed on top of the SunSDR2 PRO or QRP for cooling.

The PTT output is fitted with a CPC1035N optocoupler that separates the SunSDR2 PRO or QRP from the external device for added protection against physical damage and RFI.

Remember to activate the “AMP” button in ExpertSDR2 to activate PPT output.
