Based on transmitter data such as location and transmission power, which can be obtained, for example, from older WRTH, receiver positions can be defined using a map. At these receiver locations, the conditions of ground and sky waves can be simulated according to simplified models ITU-R P.368-10 / ITU-R P.1147-2, varying by year and time of day. The resulting data can be used in time-lapse or real-time to control the artificial carriers of the AMWaveSynth modulator, providing an even more realistic representation of the transmitted signal at specific times of day.

WRTH 1975 scenario on LW and MW

The radiosignals transmitted by the AMWaveSynth creates the impression of an active twilight zone and a day and night scene of the synthetically created radio wave bands.

The current status is displayed directly in the simulation window. Additionally, a threshold value for the radio's reception sensitivity can be specified to further filter the actually receivable stations.

Simulation, afternoon of October 15th, 18:52 , foreign radio stations can now also be received via skywave on radios powered by the AMWaveSynth.

Custom transmitter definitions can be stored as a CSV file in the tx_sites folder. Each line represents a transmitter site, consisting of the transmitters location, country code, frequency in kHz, transmission power in kW, and call/name of radiostation. Upon startup, the program searches this folder for new transmitter definitions and resolves the location data to GPS coordinates using ArcGIS. These coordinates are automatically cached in an SQL database for immediate availability upon the next program start. Transmitter and receiver locations are displayed using a TkinterMapView.

Since the AMWaveSynth also allows the firing of sferics at RF level, it is possible to define a thunderstorm area/storm cell on the map with heading, ground speed and intensity. The intensity of the simulated disturbances is influenced by the distance of the storm cell from the receiver's location. Since the storm moves across the map during its lifetime, this affects the listening experience on the radio.

We plan to further expand these features in later versions if needed and desired.

Upcoming features:

• Whether traveling through Europe, visiting distant exotic lands, or driving along the legendary Route 66 — from now on, the radio landscape will drift past your radio just as it did back when you were actually on that route. see: https://github.com/radiolab81/AMWaveSynthPropagationSimulator/tree/main/plugins/MovableRXLocationPlayer
