As per support, they were apparently out of stock, but I just got an email with a tracking number a short time ago.
So it's probably 10 - 20 days until I receive it.

 Does the Airspy HF+ Discovery have an internal Amp?
Yes. I got a Airspy HF+ Discovery a few months back.
For MF and HF, it works with a small loop of wire, even with just a dozen turns of wire around a ferrite rod.
So it must have a pretty decent internal RF amplifier.

I'm using it to stream IQ samples to my iPad from a Raspberry Pi server using hfp_tcp (a rtl_tcp "work-alike" for the Airspy HF+).

I received mine, too. I only tried it on broadcast FM so far, and it's definitely better than my RTL-SDR. Of course for an over 7x price it's better be better.

I wanted to see if there is a separate LNA inside, but peeking under the hood is not easy.

If you haven't seen in the front page, the Discovery got reviewed by WRTH here: https://irp-cdn.multiscreensite.com/46d ... review.pdf
and it got an excellent grade, as illustrated by their conclusion:
Overall, we find it remarkable and very commendable that a small and relatively unassuming plastic box should turn out to be a radio receiver with a spectacular combination of performance and versatility. And at its very affordable price point, the ratio of price to performance of the Discovery could fairly be described as stratospheric. It is highly recommended.
I'm glad that I took advantage of their Black Friday special.

And even though the outer case is plastic, most everything is under a metal shield, so a metal box wouldn't have made much of a difference.

I have been doing some antenna-tests with the 'discovery' and it is quite impressive what you can pull from this thing :)

I've had my Discovery for over a week now, and I'm continuing to be amazed at how well it works. The lowest frequency I've received a signal on was a 24 kHz. transmission from NAA, Cutler, Maine. and the highest was a 10 meter CW station. I'm using the Gqrx SDR software in my Mac with OSX El Capitan.

I'm receiving with my broadband delta-loop antenna, which is "too much antenna" for it, so I've a 6 dB., 75 ohm, CATV attenuator in the RG-6 feed line. I've found that ham SSB signals that can hardly be seen in the waterfall are an easy copy. It was money well spent, and a lot cheaper than a communications receiver!
