SKU: 104

This kit increases output power of the Sienna transceiver to 100W CW/SSB, 25W for AM/FM/Digital modes. The assembly fits in the "option port" which can also be used to house a battery for portable operation. If you have a battery installed, it must be removed in order to install this option. Board provides two thermistor controlled fan outputs which connect to the two existing fans in the Sienna. This option cannot be used standalone - it receives control information from the Sienna and will not work by itself. Orders will not be accepted without proof of purchase of the Sienna.
