APRS Data

Heatmap of sations hearing and heard by RF at the K9KMS-10 digipeater 23 May, 2026

The following represents station and packet transmissions sent and heard directly by the K9KMS-10 station via RF. Repeated and internet transmissions are excluded in order to determine the efficacy of this Alinco DR-135T/Argent T3-135 Digipeater IGate station. The graphs and images below are updated frequently with data publicly available at APRS.fi.

The distance from which stations are heard is sometimes significantly greater than normal due to the effects of Tropospheric Ducting and Sporadic E propagation occurring over and around the Lake Michigan area. Stations sometimes report from as far as Marquette in Upper Michigan, Detroit, and Chicago. Learn more and see the forecasts at Tropospheric Ducting Forecast, Hepburn Tropo Index.
