December 2025 Update TL;DR The $15 GPS dongle is generating severe RF noise. I was tracking down some QRM (man-made interference) in my sBitx radio that was especially bad on 10m, but still present on 15 and 20 meters. After returning from a portable activation, I noticed that the noise was gone. Then I noticed that I had not plugged in the GPS dongle. Plugged in the dongle, QRM was back. Unplugged it, QRM gone! Searching online, I found this discussion about cheap VK-162-based GPS dongles from Amazon creating QRM. I have tested 3 of the VK-162's...with u-blox drivers on both Win10 and Win11.
