Thanks Robin.  I'd already mentioned this.

But there *WAS* a product (not in the NI catalog) many years ago that Ettus was building on an order-by-order basis that was   a 4-channel (or was it 8?) RX-only device, using a YiG-based synthesizer.  I think it was likely before your time at Ettus/NI.

In my guise as a radio astronomer and manager of a radio-astronomy observatory, I'd love a many-channels, brutally-coherent, RX-only
  device.  But the market is small....

Hi Marcus,

Thanks for promptly replying. Has E330 ever been offered for purchase? If so, has it been discontinued?

Best,
Temir

    Hi there,

    I recently came across a presentation by Matt Ettus at grcon16
    <https://youtu.be/kEAkIfWViQo?t=1254>, where he introduces
    E330 as a receive-only alternative for E-series USRPs. I
    checked Ettus store as well as googled for some info about
    E330 but could not find anything useful. Has it ever been
    offered as a product by Ettus or NI?

    As a general question, most of my applications are
    receive-only in nature (spectrum monitoring etc.) and usually
    Tx channels of the USRPs end up redundant. Is it possible to
    purchase rx-only devices?

    Best regards,
    Temir
