So, one question is, assuming it's in there somewhere, how do I find it?
After that you need to install whatever SDR software you want to use. We recommend CubicSDR and the AppImage you could try is on our Downloads page (https://www.sdrplay.com/downloads)

Sorry to seem like such a dweeb, but there is no antenna under that red plastic cover. I presume that might be the problem but I find no instructions anywhere about what kind of antenna to connect and where to get it.
under the red cover is the antenna socket which, in radio terminology, is a 50 Ohm impedance input. This means that an antenna is needed.
You can either connect an antenna directly to this antenna socket, or indirectly by having a length of coaxial cable( see https://en.wikipedia.org/wiki/Coaxial_cable which allows you to connect the antenna some distance from where the RSP unit is located. Lower frequencies will also be prone to noise and wire antennas for them, need to be physically much bigger than can comfortable be accomodated indoors.
The reason you might want to add a length of coaxial cable is that if you are deep indoors he signals will be significantly weaker than having the antenna outdoors/ higher up in the open.
The simplest, optimum, non directional antenna you can have is a quarter wavelength of conductive wire - here's a calculator which converts frequency to length of wire (metric versions are also available) http://www.csgnetwork.com/antennageneri ... ncalc.html
So for 162.4 MHz, a length of wire 2.34 feet (71cm) is ideal. In practice exact measurements don't matter too much, which is why a telescopic whip antenna will work quite well from 50 MHz to several 100 MHz.
So if you're already getting strong signals on another indoor receiver, the simplest thing to do is to connect a length of wire to the centre connection of an SMA plug and screw it onto the antenna socket. Many people use an adapter to a chunky SO239 socket which then allows them to insert a bent over wire or banana plug directly into the centre. See this old video, 1 minute 30 seconds in, which shows connecting to the centre of the SMA socket https://youtu.be/TJSctUv5lUc

Good luck, Jon

Is there something simple I need to check, or is it just broken? I looked at the list of rigs and there is no RSP1A choice. Hoping for something simple, not looking forward to returning the device for replacement. And thanks for all your help so far.
I have installed SDRplay_RSP_API-Linux-2.11.1.run in Linux Mint, everything seems ok. I installed CubicSDR-0.2.3-x86_64.AppImage on your advice and everything looks ok. I have installed a known working antenna that gives me good voice with full quieting on an adjacent HT. When transferred to the RSP1A in gives no reception using NBFM and the local weather frequency (the one giving good voice on the HT). I have three USB cables, all previously know to be working, tried all of them, no effect.
OK, in desperation I went over to Win7 and installed SDRuno as per your video. Everything looks ok on the install but it reports that it cannot find the RSP1A and suggests I check the USB cables, drivers etc.
It appears at this point that the RSP1A arrived in non-working order. I'm still hopeful that there's some small thing I can click to make it right. If not, can you tell me how to go about getting a replacement?
I have no idea why you can't open a ticket. Please send an email to email@example.com listing your issues and we will open a support ticket for you once we have your email address. All RSPs are fully production tested so it would be unusual for yours to be non-functional.
