    $259 delivered to Brisbane. Just for comparison, the RSP1B is US$152.93 (~AUD$244) delivered from SDRPlay on a website that looks like it was written in notepad. No local support though.

    The key advantages over the RSP1A are that it comes in strong black painted steel case instead of plastic, and (compared to the RSP1A) has significantly improved noise performance below 1MHz (i.e for LF and below), and in the 50-60 MHz region. There are also noticeable noise improvements in the 3.5-5.5MHz and 250-320MHz spectrum. It also has it has improved signal handling at HF frequencies compared to the RSP1A.

      SDRplay provide plenty of support IF you need it. Only other consideration is both the RSP1B and RSP1A only have 1 antenna port, hence why I went with the RSPdx

    • my bad, I remember the price was higher from UK.

    I haven't heard of this, thanks OP. What a nice bit of kit.

    My DSO goes up to 500 MHz, this'd be handy for above that. Looks like a bloke has made a great looking spectrum analyser for it too:

    And he has info on making a tracking generator which would mean you could set up a bit of a VNA, but up to 600 MHz. I've been meaning to get a LibreVNA for my work as I work with higher freqs but this is still great stuff for the price!

    I have an RTL-SDR which I was playing with for a while, but now it's permanently hooked up to an ODROID (RPi alternative) as a flightradar24.com feed.

    • Thanks for the link. I had an AD9850 which is also used in that project. I built a function generator and oscilloscope with AD5932, though that was more than a decade ago.
      One of my friends recently got a LibreVNA, which looks great, and I believe it can go up to 6 GHz. My RTLSDR is hooked to my HA VM, running rtl_433 for 433 MHz temperature sensors.
