Well, after 24 hours, I checked the stats again without the logger installed. My reception rate on the ISS was still 98%. But the wind one was even worse! Only 58%. So I can report to everyone here, it’s not the logger.
My guess is I’ve been having an issue with the location of the second console, and just didn’t know until I had something actually logging it. Problem is I could move the console to get better reception. But then the console is in a place in the house where I won’t be able to conveniently read it. I like to read the temp/wind on my way out the door.
So I’m just going to hang onto the logger for now. I’ll just have to flip my current setup over still using the existing serial logger.
