The Xeigu G-90 HF Transceiver radio is very popular for a few reasons. It is a great little HF radio that is under $600 and it is very portable as a smaller footprint HF rig. With a max output of 20 watts this radio is great if you are on a budget. Do not underestimate the power of this radio at only 20 watts. One of my ham buddies has used this for over 6 months straight and logged over 4000 contacts both local and DX doing POTA AND FT8.
At the time of this writing the Xeigu G-90 is running $449.95.

You will, of course, want to consult with your operating manual for a more detailed explanation of the functions of the G90, however this page will at least allow you to familiarize yourself with some of the features. If you are looking into getting a G90 as an HF rig for your shack, this will also help you out a bit and determine if you want one. I highly recommend that you find someone with a G90 and ask to play with it a bit and have them show you around the radio. They are easy to use and fun to work with at home or out in the field.
