During several months of observing the Eastern/Central RV Service Net and providing remote station access to W4BXI, the ability of net participants to communicate was analyzed.
The results of our study are presented in this document (PDF), which is focused on the 40 m band propagation during the time frame of the morning net on 7191 kHz. Marginal radio propagation at the current low point in the Solar Cycle makes it difficult for net participants to hear each other.
Our presentation combines observations of signal levels, net participant reports, ionospheric "soundings" and propagation modeling.
