Does anyone know the frequency/tone combinations for the [relatively] new fireground channels (A through D)? I believe all four use 868.9875, but I don't know which PL/DPL.
They should be rebanded, try 853.9875. If there are others missing that are not licensed, try 853.9375, 853.8500, 953.9625, 853.9750 as well. All these channels are available to any PS 800MHz licensee.
