Nils Reviews the RX-888: A Sub $200 16-Bit 32 MHz Bandwidth SDR

A lot of affordable Chinese clone SDRs have been coming onto the market
recently, and the RX-888 is one of the most interesting. The RX-888 appears
to be an improved clone of the RX-666 which in turn is a clone derived from
Oscar Steila (IK1XPV)'s BBRF103 original open source design

.

The RX-888 is based on the LTC2208 16-bit ADC chip which is capable of
streaming the entire 1 kHz to 32 MHz frequency range to the PC over USB 3.0
with direct sampling. Frequencies from 32 MHz to 1.8 GHz can also be
received via an R820T2 tuner which is on the board (the same tuner used in
most RTL-SDRs). Due to the bandwidth restrictions of the R820T2 silicon,
the bandwidth above 32 MHz is restricted to 8 - 10 MHz. The main change
when compared to the RX-666 appears to be that there is an LNA which
improves medium wave and small antenna performance which was a problem on
the RX-666. The RX-888 also adds several heat sinks to the enclosure, as
excessive heat generation of the LTC2208 ADC appears to also be an issue.

Recently Nils Shiffhauer (DK80K) wrote up a great review of the RX-888
<https://dk8ok.org/2020/09/04/rx-888-32-mhz-16bit-200-us-pricks-up-your-ears/>.
In the review he covers the specs, shows a few screenshots of some signals
he's received and also provides multiple audio samples of signals received.

The RX-888 is currently available on marketplace sites like Aliexpress and
eBay priced at around US$180. In the past SDRs that could receive the
entire HF band at once were rare, with the only affordable SDR with this
capability being the KiwiSDR. So it is good to see that we may now be
entering a stage of new advancement in affordable SDRs.

One thing to note is that this design can be considered a clone. However
the original design by Oscar is open source and from this post on his blog
<http://www.steila.com/blog/index.php?controller=post&action=view&id_post=32>
he seems happy and accepting of the clones.

We note that we have ordered a unit and will be uploading a review once we
test it.
