    I had a reply from Radio Analog:

    Hi Frank,

    Thank you for your interest and we appreciate your valuable feedback.
    As you see in homapage text, we mentioned that ICOM-7300 is direct sampling receiver. We know that there is no frequency conversion but actually we havent find better term than IF and supposed every amateur know how their rigs works already. Taking your feedback seriously we are going to add a short explanation.

    Keep watching website for updates please.

    Kind regards,
    Radio Analog Team.

    I had another look at the PTRX-7300. I think I get it now. The following features are of interest:

    Dual Receivers Mode: YES
    Simultaneous Operation: YES
    RX/TX Monitoring: YES
    SDR Port to RF tap Point Isolation: High (>60 dB (average), Amplifier Reverse Isolation)

    If you are getting one, please let us know how it performs in actual use.

    For me, this solution is too restrictive.
    Having the band pass filters in line will no doubt help a cheap SDR dongle but this comes at a cost.
    The band pass filters restrict any second RX's usefulness to the band currently selected. With the higher bands, the filter bandwidths are greater but operating on say 80m, the 2nd RX could not be used on a different band.

    Having two receivers on the same band is not something I need.
