The SoftRock Lite II kit now includes the components to build it for one of the following bands: 160m, 80m, 40m, 30m or 20m. This replaces prior Lite II kits that were set to a specific band when ordered. The SoftRock Lite II provides a simple to build SDR receiver with a fixed center frequency to be used with a sound card that can sample at 96 kHz, providing band coverage from 48 KHz below the center frequency to 48 KHz above the center frequency.

The SoftRock RX Ensemble II Receiver Kit includes the components for building the kit for LF, 180kHz through 3.0 MHz, operation or for HF, 1.8 MHz through 30 MHz operation. A second 74AC74 position provided on the circuit board gives an additional division by 4 on the Si570 clock signal for LF operation. For HF operation the second 74AC74 is not mounted on the board and an HF jumper is installed to route the Si570 clock signal directly to the 74AC74 that is used for quadrature clock generation.

The SoftRock RXTX Ensemble Transceiver Kit provides a 1 watt SDR transceiver that can be built for one of the following four band groups: 160m, 80m/40m, 30m/20m/17m or 15m/12m/10m. Components are included for all four options and can be assembled at the builders choice. The kit combines the functionality of the prior SoftRock v6.3 RXTX+Xtall Transceiver Kit, the USB I2C Interface Kit and the PA Filter Kit on a single circuit board with connectors along one edge for easy access.
