[CQ-Contest] MFJ 1708 alternative

[John Geiger]

The MFJ 1708 unit allows you to attach a SDR receiver or other receiver to
your antenna and transceiver, allowing for dual receive and/or a spectrum
scope:

Is anyone aware of a similar product made by another company?  Dual receive
can be very handy in contesting and DXing.  I wouldn't be doing SO2R, just
listening with another receiver to another band or a different part in the
same band.
