This will depend on the terrain. If you are trying to communicate over water you could get up to 12 miles in ideal conditions. Over fairly open country side with few trees expect up about 4 miles. In dense forest or in the middle of a city range could be as low as 500 yards.

Yes, this is possible. Most radios can be repaired unless they have had a physical shock which has damaged the PC board or liquid ingress has caused bad corrosion to the components. There are other faults which are not repairable due to the age of the equipment or unavailability of spare parts. If your XTN446 is getting hot around the display area this is usually due to a fault within a non replaceable component.

This will depend on the amount of times you transmit. While the radio is transmitting it is using a large amount of current from the battery. When receiving a message, extra current is used (not nearly as much as when transmitting) and the higher the volume the more the battery is drained. So, a battery could last for thirty six or more hours if the radio was turned on and no meaages were received, or as little as two hours with almost continuous transmission. Of course all of the above depends on the age and condition of the battery.

Hi Jim,
This is a problem caused by a IC failure and also occurs with the XTNi. This can usually be repaired and will cost £29.99 plus return shipping.
