Passing contemplation, but with near triple digits predicted the week to the Eastern USA, just before the 4th Of July holiday weekend, could bring us some neat late night & early morning Tropo for DX'ing VHF & UHF bands. DX Maps is good, for those posting what they work.

So, happy VHF / UHF DX'ing? Might as well look at one bright-side of this heatwave. Might as well include the rest of DX Infocenter. https://www.dxinfocentre.com/index.html
BTW, nice tutorial on Tropo Propagation Modes. https://www.dxinfocentre.com/propagation/tr-modes.htm That one on -TR, TROPOSPHERIC SUB-REFRACTION , I didn't really know that as a happening, but I have experienced it on distant FM / TV stations, and 6GHz point to point Microwave links. The links would be affected, I'd get called-out, but would find nothing wrong with the equipment. Then, like magic, signal is back to normal. Good INFO!!!!
