With this fist day of summer heatwave, starting in WV, Friday 6/20/2025, we may go to around 100 degrees this weekend and into next week. So, could that mean some nice VHF / UHF Tropo Propagation? Hope so... https://www.dxinfocentre.com/tropo.html Especially, late night and very early morning. Our 162MHz Weather Stations make for some nice tax $$$$ bought VHF beacons. Oh yeah... Need an OTA Antenna for UHF HDTV DX reception? Build one. https://archive.org/details/pren2mdvuhfindoortvantennaandtestpdf/6342862%2C%20Pamphlet%2011-2014%2C%20hi%20res/

When, I woke-up for a bathroom break at 3AM, I checked the WX FREQ's on the indoor scanner's antennas. And, the Ashland, KY station marched in at full quieting, 162.550MHz. Normally, I can't even pick that up indoors, and it's very weak on the outside Discone. So a good opening to the West.

Another stretch of mid-90's in the Eastern USA / Canada could be another chance to chase VHF / UHF DX this 4th Of July holiday weekend. Kind of cool, when you could get out to +80 miles on MURS, GMRS, and those HAM Simplex 2M, 222MHz, 440MHz, 902MHz, and even 1294.500MHz, FREQ's. If you have SSB / CW / FT8 HAM Bands capabilities, send out CQ-CQ when you notice those Weather 162MHZ FREQ's being heard further. You'll just never know.

With this weekend, 9/13 - 9/14/2025, with temperatures getting to near 90 degrees in the days, and 50's, or lower, at night, might prompt conditions for Tropo Propagation again in the North East USA and Southern / Eastern Provinces of Canada. (Might...) https://www.dxinfocentre.com/propagation/tr-modes.htm With the ARRL VHF Sweepstakes this weekend, that could be a VHF High Band and UHF helper. Use those 162MHz Weather Stations as propagational beacons. (Hey, our taxes paid for them.) Not a HAM, then you still have VHF MURS Band, and then GMRS in UHF. I would love to see the conditions of late September 2004, where VHF High Band and UHF FREQ's acted like the 40M Band in the daytime. Folks in Rochester, NY were watching TV stations from Beckley, WV. I'd love to see that happen again. FM Broadcast Band DX'ing seems more difficult today, with all of these FM Translators on-air littering up that band.
