Same as TD-H3, but with the following updates: Upgraded firmware,
240 MHz processor vs. 30 MHz on standard TD-H3, 128 MB memory vs. 1
MB on standard, Bluetooth 5.1, BR, EDR, and BLE 4.2 on Plus model
vs. BLE 4.2 only on standard. TD-H3 Plus also has Global Intercom
via App.
All TD-H3 radios can be set for 1 of 3 different modes: Ham, GMRS,
or Normal. Ham only TX on 2m/70cm, GMRS only TX on FRS/GMRS
channels, and Normal can TX/RX on all possible frequencies. This
can be set with a special power-on sequence.
