This Instructable demonstrates how to modify a standard Icom IC-T7H hand-held dual-band radio transceiver to both receive and transmit on a wider range of frequencies.
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
There are 10 screws that need to be removed to gain access to the internal control circuitry.
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.
