While using a Verizon 4G-LTE hotspot at the Control site, I got comments that my CW turned into random garbage now and then. A Wifi speed test showed the down speed about 8 Mbps, and the up 0.25 Mbps or worse. Not good. I was able to get a prepaid Comcast service that remained at 20 Mbps down and 1.0 up. Not very impressive numbers, but it has worked perfectly on CW, FT-8, and SSB. (K3, K3/0 mini).
