Brick2 SDR is a continuation of the first version of the transceiver Brick SDR ie. Hermes-Lite EU1SW with minor improvements and changes. Developed by special order. Has a main board, on which all elements are located, such as LNA, Step ATT 0-30 dB, including power amplifier and 7 LPF.
The power amplifier is made according to a push-pull scheme on a pair of RD16HHF. The output power on 160-10m 10-15 watts, 6m 8-10 watts.
Can be used up to 4 rigs in one network.
The SW is still under development. There are some functions of controlling externals PA:
- Serial interface for Hardrock-50 TTL 3.3V (need tested).
- Band voltage for Xiegu XPA125B.
- Decimal (BCD) as Yaesu, Elecraft.

Just wondering and you you have probably been asked a lot , will your unit have
an options for pure signal ? If so when would it be available ?
Thanks
Steve
it is available out of the box.
BRICK2 SDR is a cracking little SDR, i would recommend anyone thinking of getting into SDR, get on purchased.
