Estimated 6.2 mV/m. Reliable in most conditions. Skywave interference unlikely during daytime.
Radio signals do not travel in a neat circle from the tower. The ground between you and the transmitter matters: saltwater carries AM signals farther than dry rock, and a ridge between you and an FM tower can cut reception completely. This planner models those effects with a terrain roughness factor and day/night propagation switches so you can see realistic differences before you pack the car.
Set your pin near Terra Nova National Park or the Trans-Canada stretch past Badger. VOCM 590 AM holds strong coverage through most of the route during the day (solid green ring extends about 180 km over average ground). At night, the ring widens but you may hear co-channel interference from distant stations. Check the Alternative Stations panel: CBC 740 AM provides a strong backup across central Newfoundland, and OZFM 94.7 FM covers the urban endpoints well but fades to fringe in the interior valleys. Print the report so you have frequencies written down when cell service drops.
Place the pin near Elliston or Port Union. With terrain roughness set to Hilly (level 3), VOWR 800 AM shows fringe coverage because low power and rocky ground limit range. VOCM 590 AM provides strong daytime coverage. Try toggling to Night mode: AM skywave can bring distant stations but also noise. FM reception for OZFM 94.7 may be weak unless you have a rooftop antenna pointing toward St. John's. The terrain slider helps you model the difference between a seaside cabin (flatter, better signal) and one tucked behind a hill (weaker).
Set terrain to Mountainous (level 5) and your pin near Rocky Harbour. The planner shows most FM stations dropping to gap zones because the Long Range Mountains block line-of-sight paths from St. John's and Corner Brook transmitters. AM stations fare somewhat better: CFCB 570 AM from Corner Brook gives fringe coverage along the coast, and CKGA 570 AM from Gander may reach the northern peninsula in Night mode. This route is a classic case where printing alternative frequencies ahead of time saves frustration.
| Class | Max Power | Typical Day Range | Example Stations |
|---|---|---|---|
| AM Class A (clear channel) | 50 kW | 250-400 km | CBC 740, CFCB 570 |
| AM Class B (regional) | 10-50 kW | 100-250 km | VOCM 590, CKGA 570 |
| AM Class C (local) | 1 kW | 30-80 km | VOWR 800 |
| FM Class C1 (high) | 100 kW | 70-120 km | OZFM 94.7 |
| FM Class A (local) | 6 kW | 25-50 km | CHOI 98.3 |
Power class is the single biggest predictor of coverage. A 50 kW AM station on a clear channel can reach across half a province during the day and across a continent at night (with interference risks). A 1 kW local AM serves one town and its outskirts. FM stations rarely exceed 100 km reliable range due to the radio horizon, even at high power.
