Transmitter

The audio quality is very good when speaking about 1" across the front of the radio. Power levels were right at the advertised rating of 10W. The power levels below were taken a calibrated Bird Wattmeter.

TD-H8 Ham	High	Med	Low
VHF	10.5	3.2	0.7
UHF	9.8	4.3	0.7

Receiver

Receiver sensitivity is very good with plenty of loud audio. A press of the side button activates the FM broadcast radio which stays active until activity is detected on the main channel. When the received signal disappears, the FM broadcast station will return after 5 seconds.

A Long Press of the scan key activates the scan mode with a speed of approximately 5 channels per second.

Display

The 1.7" LCD has excellent resolution . The channel name supports up to 8 characters.
Here are display samples.

Programming

The TD-H8 can be programmed in a variety of ways. Of course there is always manual programming, but along with the Factory Software the radio can also be programmed using CHIRP.

If you do not have a computer handy, TIDRADIO also has a recently introduced BL-1 Bluetooth Programmer which has apps for both Android and iOS.

Programming Cable

The required cable uses a UART chip in the USB connector. The proper drivers for this cable should load automatically. The connector is a standard K1 so standard accessories are compatible.
