I already have the QS1R so for me would be just adding the QS1E. The
power levels are perfect for the transverter to 1296 that I have. the
HPSDR filter and amplifier boards might be the add on you are looking
for. Some hardware and software integration needed.
HPSDR has been around for quite a while. Web search HPSDR and you find
it. Is a TAPR and others project "High Performance SDR" with boards sold
by TAPR and others. Two versions right now. One is multiple boards that
fit on a motherboard. And a one board integrated transceiver. Same issue
for all of these, i.e. you have to then add in filter boards and power
amplifiers. Designer of the QS1R and QS1E was part of the original
HPSDR team until they parted ways.
http://tapr.org/hpsdr_index.html to purchase production boards
http://openhpsdr.org/ with a wiki at
pre-production interest is gathered at
