I did an earlier prototype version of the SoftRock and paired it up with a NJ QRP DDS board, an Atmel Butterfly and KD1JV's code for the butterfly to get a variable local oscillator on the Soft Rock. Worked quite well. More info can be found at: http://ewjt.com/kd5tfd/sdr1k-notebook/sr40/index.html The version of the board I've got on the web site does not match the current board Tony's distributing -- this was an earlier version of the board.
I'm not sure on the current boards, but the original one I did the detector response was wide enough one could run it with a 96 khz sampling sound card without difficulty. I don't know if Tony's tightened up the detector pass band in the most recent version, sort of suspect he didn't. The intent of the board was to come up an inexpensive piece of hardware that would allow people to see the benefits of SDR and one of the things we wanted to do with it was used it with 96 and 192 khz sampling cards. . I've used it with a modified version of PowerSDR from Flex Radio and also with SDRadio -- works well with both.
