I have used this rig on digital, SSB, CW and have been amazed how great it performs. This rig has exceeded my expectations of one in this price range. Soon after its arrival it went up north with me for a long vacation. My location up north is a perfect environment to test a radio such as the SG-2020. The location is rather primitive and devoid of hydro power.
Operation is dead loss from a storage battery.
Overall I was quite pleased with its operation. It is a very easy radio to use. On CW, the SG-2020 is very nice to use and I had no problem with it at all. Some near by signals were quite strong and I was able to separate them from the desired station quite easily. The little radio is quite impressive, and I did have quite a bit of fun with it.
