New Dragonfly wide band SDR with 32 MHz bandwidth

Many thanks to SWLing Post contributor, Franco (K4VZ), who writes:

Last night I came across a new SDR receiver from China called ‘RX-666’. On paper its specs are interesting: 16bit ADC, max sample rate 32MHz (in theory one could sample the whole LW+MW+SW bands at the same time), USB 3 interface, and tunable from 1kHz to 1.8GHz.

Its design seems to be a “derivative” of Oscar Steila’s (IK1XPV) BBRF103 SDR – see this post from Oscar – it looks like they upgraded the ADC, made use of a better voltage regulator, and moved to a 4-layer PCB (the original was a 2-layer PCB).

Unfortunately (for Linux people like me) they only have proprietary drivers running on Windows.

Besides the AliExpress store, I saw it is also available on eBay – the AliExpress vendor has two versions, a cheaper one with a ‘standard crystal’, and a more expensive one with an ‘upgraded crystal’; I messaged them earlier to find out what is the difference between the two, but I haven’t heard back yet.

I thought some of those readers of the Post who are interested in capturing large parts of the radio spectrum to decode later might want to look into this SDR receiver.

Thanks for the info on this SDR, Franco. I was not familiar with it. A 16 bit wide band SDR with a 32 MHz working bandwidth is most impressive–I’m sure FM DXers will be following this closely. I’m glad they’re using a USB 3.0 port but am very curious if it can even handle the amount of data should a user initiate a really wide spectrum recording. Perhaps recordings have capped bandwidths?

As a side note, someone should tell the manufacturer that their model number “RX-666” is…well…a culturally sensitive number!

Post Readers: Please comment if you’re familiar with this SDR.

QSO Today Virtual Ham Expo 2020

Many thanks to SWLing Post contributor, Franco Venturi (K4VZ), who writes:

I just found out that the podcast ‘QSO today’ has organized a ‘Virtual Ham Expo’ (https://www.qsotodayhamexpo.com/).

The current list of speakers and their topics looks interesting (click here to read), and I thought you and other readers of the SWLing Post might be interested as well.

Thank you so much for the tip, Franco. I’ve been meaning to post an announcement about this online event.  It seems to have attracted a lot of vendors and at least early bird registration for the show is free. Vendors do pay fees to host virtual booths at the events.

There are a number of great presentations in the line-up, so I would highly encourage readers to check out the presentation schedule and register for the expo.
