Hi Mike,

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. to purchase production boards with a wiki at

pre-production interest is gathered at
