July 2026 heatwave to bring-in possible VHF / UHF Tropo? And, -TR???

(1/1)

ThaDood:
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.   
https://www.dxmaps.com/spots/mapg.php?Lan=E&Frec=50&ML=M&Map=W2LN&HF=N&DXC=ING2&GL=S   Then, this site could be useful.    https://www.dxinfocentre.com/tropo.html     Of course, this all may happen after the ARRL June Contests, (VHF & Field Day.). but that's what usually happens. 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!!!!
