Featured in the March/April 2022 issue of ARRL's QEX Magazine. BUY IONOS

The Amateur Radio Safety Foundation introduces the IONOS Channel Simulator, an audio-processing radio path simulator that models common HF and VHF/UHF propagation channels. It is intended to accelerate modem and protocol design, analysis, optimization and comparison, but has other uses as well. BUY IONOS

New Experimental HF Propagation Map

Lee Inman of the Winlink Team has mined the server databases for useful propagation data and developed a new map showing recent HF connection paths on a worldwide basis. You can view the new map here.

Stations that do not report gridsquare positions (especially gateways) can not shown. If you aren't seeing your QSO's check your software settings. BPQ gateway programs generally do not report positions for sessions. The controls in the upper left of the map should be self-explanitory, but if not let us know. Mouse over a path line and see details of the QSO.

Please send us a comment if you like the map, and make any suggestions you feel would make it more useful to you.
