2 Meter: 144.0-148.0 MHz
70 Centimeter: 420.0-450.0 MHz.
2 Meter: 118.0 - 174.0 MHz
70 Centimeter: 400.0 - 470.0 MHz.
Hopefully this will be the first of many ham radio related Instructables I will post.
This modification should only be made in preparation for emergency situations where communications out of regular ham bands are necessary, at no other time should an amateur radio operator transmit on frequencies outside of ham bands.
Step 1: Step 1, Disassembly
Four above the battery compartment
Two at the top of the battery compartment
And two at the bottom of the battery compartment
Remove these screws and set them aside carefully so they don't get lost or knocked around and then proceed to step two.
Step 2: Opening the Tranciever and Identifying D15
The top "controller unit"
The back-plane "logic unit"
And the battery compartment cover which is just a piece of metal.
Next take a second to locate D15, a 3 pin diode in the lower right of the back-plane logic unit.
After locating the diode and checking out the rest of the awesome circuitry head to step three.
