Hi, KD9PWC here. I'm setting up my first station. I'd love some advice on how to get up and running here in the frozen Midwest. My ham shack is in a bedroom directly above the electrical service meter/panel. I have purchased a window feedthrough panel for my ground and coax to get outside. Problem. Ground is frozen. I was able to locate the grounding wire running from my service panel to the ground electrode. Question. Can I attach my ground wire to the exposed service panel ground wire, or do I need to keep digging to find the rod and attach it to the rod? Thanks in advance for any help.
