Uh-huh... This weekend, the Amateur Radio bands will go nuts with activity for a 24hrs period.
https://www.arrl.org/field-day But, if you should want to avoid this, then the WARC bands, and the 5MHz (60M), Band, is a great escape. One thing about this heatwave going on is for some nice enhancement in the higher VHF and UHF bands, with Tropo Propagation, especially late night and early mornings. I believe that National Simplex 146.520MHz FM is forbidden to use for contesting, but all other Simplex FREQ's should be game. Happy contesting???
