Frequently asked questions
How do I connect the DC power cable to the vehicle battery?
Locate the power input connector near the transceiver, route the supplied DC power cable to the battery, connect the red lead to the positive terminal and the black lead to the negative terminal, then secure the connections.
What antenna impedance should be used with the TH-9800?
Use a 50 Ω impedance antenna with a low‑loss coaxial feed‑line to match the transceiver’s input impedance.
How many memory channels are available on the TH-9800?
The transceiver provides 800 memory channels, each with independent settings.
