Does anyone know what TG Tanker 95 would use?
They don't. No 800 radio on the plane. Kansas Forestry is trying to get funding to get one for it, but aircraft rated radios are very expensive. They use a couple of VHF channnels to communicate with a spotter on the ground. I believe they are itinerant channels or VTACs.
Start with the National Flight Following frequency for firefighting aircraft
168.65 nfm
Also 168.625 nfm this is National Air Guard frequency.
listen for frequencies given out to the aircraft for air to air and air to ground contacts.
Not sure of the location of an air tanker base, but try
123.975 or 123.925 am
