1899 kHz Midday Propagation Test

This blog documents the results of mid-day North American 160 meter propagation. Daily test started in 2017. The daily blog has documented the activity since December 1218. Most of the regular activity has been by stations in Florida, Georgia, South Carolina, North Carolina, Michigan, Minnesota, Iowa, and Mississippi. All stations are welcome to participate.
