Two days - Tuesday June 27th and Wednesday June 28th.
On June 27th, I went out to the car during lunch and had two QRP QSOs. One was with KI4PP in Ashville, NC and the other was with WB6HGJ in San Diego, CA. Wow! 5 Watts from a Hamstick magmounted on the top of my car all the way across the country!!!
On June 28th, I went out to the car during lunch (same time) and heard nothing. Well, almost nothing. I heard a few QSOs in progress; but nothing compared to the amount of signals I heard yesterday.
Propagation is indeed a funny thing. However, it also makes Amateur Radio the immensely enjoyable avocation that it is; so I'll live with it (like I have a choice!).
