QSX is coming soon. https://www.qrp-labs.com/qsx.html

Just google like any other technology. Answers are all out there. I never went to any amateur radio clubs. I paid up to do my exams, bought a radio and just wobbled into the bar like a drunk.

Also you don’t have to talk to someone past exchanging RST etc. If they start going off on one just tune away.

can you explain how QSX is different from the other SDRs being mentioned (ADALM-PLUTO, HackRF One, etc)? Is it just more transmit power than those other SDRs? I feel like i'm missing something.

It is a SDR-based HF transceiver instead of wide-band SDR. SDR is implementation detail and extra feature. Most SDRs are receive only, and the ones that can transmit, like ones you listed, are limited in power.

The other difference is interface. The QSX, and other SDR-based transceivers, work like other regular transceivers. They have USB port for computer control and sound card output. Some newer radios provide I-Q input and output which can be used for more advanced modes. But the bandwidth is limited compared to the SDRs which can monitor an entire band.

So would you recommend the QSX as a good way for a beginner to get to explore all the different bands/modes? Do you think this is a good replacement to - say - a hackRF? Or is the hackRF better for specific use cases like debugging because it has wide bandwidth?

When you're doing RF stuff you're usually really only interested in single signal reception and usability. To learn about the various modes this will be way better than an SDR.

The SDR sure has utility but that comes at a compromise. I've done some professional RF stuff in the past and 99% of the problems are solved with very simple and way more precise gear compared to an SDR.

Have a look at http://websdr.org and have a play around with SDRs and then go look at a video for a Yaesu or Icom "rig" and see the difference in the usability. The QSX is more the Yaesu or Icom end of things.

Well i'm sold, can't wait for the QSX to be released so I can really start using my AE license! Thanks!

Before you do, if you have money available to throw at it, I'd probably go for a commercial rig first that can kick out 100W and start there. Yaesu FT-450D is the sort of thing that's a decent "first rig".

If you can't afford it, go for the QSX! I may replace my commercial rig with one if it's any good.

One's a transceiver. One's an SDR. The first is way more human oriented and focused on utility.
