To help you get the exact technical guidance you need, tell me:
For most users, the user manual is sufficient for programming and daily use. But if your TH-9800 develops a fault, the service manual is the only reliable path to restoration – short of shipping the radio back to China for repair.
: Inject a precise, low-microvolt RF signal from your generator into the receiver. Adjust the squelch threshold pots until the squelch opens exactly at the factory-specified signal-to-noise ratio. Safety and Best Practices
: Selectable AM reception for VHF frequencies, specifically for Air Band listening.

Provides PCB diagrams showing the exact location and value of every component.
A comprehensive parts list is provided for technicians to identify and replace components:
Over time, the MOSFET finals (often the RD70HVF1 or similar) can degrade. If your radio only puts out 5W instead of 50W, the service manual shows you the bias adjustment pots and the correct voltage points.
The Tyt TH-9800 consists of several key components:
