What would be nice (MK2) is no matching at all but a user output to select appropriate filtering/,matching circuits to cover the band in use. Generally a wide band front end will be totally overwhelmed by local strong signals, no matter how good it is. I know this because for example my Ettus B200 which has similar dynamic range, can't be used without a filter due to a pager site a mile away. Everyone in urban areas is likely to have these problems, even in the US. So filtering is needed for any serious use.
HF only use of this device to me seems pointless given there are so many options out there, e.g. RFspace that have great performance, filtering and support. It is probably better not to use a silicon tuner at all. HF is baseband in effect. Using a direct connection to the ADC/DAC could give coverage down to DC that would avoid spurious responses associated with a direct conversion to 30MHz.
Finally - again in MK2 can we please use SMA connectors and put them on the edge of the board so they can be used directly like everyone else does?
