MTP850

1W Tetra portable.
This is what you should buy instead of the MTH800.

Everything about this handset is better than its poor cousin. Batteries are quickly swappable with no silly battery doors, the same accessories fit, and the PTT is a 1000 times better to get along with.

For a bit more money, the MTP850s has a "High RF Power" function, offering 3w output power.
