Skywave propagation nuts and bolts including ionization and recombination (Brittanica) How far can two-way radios communicate? Understanding solar indices (ARRL - excellent article) Quick Guide to HF Propagation Using Solar Indices (what it all means) How the Sunspot Cycle affects radio propagation (by Noji) How weather affects radio propagation (it can affect the conditions, but no set answer fits all)
On the other hand, lightning is the single largest contributor to atmospheric noise Furthermore, temperature inversions can result in tropospheric ducting, which typically affect frequencies greater than 90 MHz |
