Features of the TL-922
The Kenwood TL-922 is an amateur radio power amplifier designed for use with shortwave radio
equipment.
Here are some interesting details.
Output power: The TL-922 can provide a maximum output power of up to 1500 watts in SSB (Single
Sideband)
mode and 1200 watts in CW (continuous telegraphy) mode. This allows for higher transmission power,
which
can help improve signal quality and transmission distance.
Frequency Coverage: This amplifier covers a wide range of amateur radio frequencies, typically 1.8
to 30
MHz. This allows it to be used on multiple radio bands and makes it compatible with a variety of
amateur
radio equipment.
Vacuum Tubes: The TL-922 uses an amplification setup based on vacuum tubes (electronic tubes).
Specifically, it uses a combination of two 3-500Z tubes in a Class AB2 linear amplifier
configuration.
These vacuum tubes are known for their durability and ability to handle high power outputs.
Protection and safety: The amplifier includes built-in protections to prevent damage in the event of
a
bad connection or improper operating conditions. It also has a cooling fan to maintain a suitable
temperature during prolonged operation.
Additional Features: The TL-922 has output power adjustment controls, a built-in power meter to
monitor
output, as well as an SSB/CW mode operation switch. It also has antenna and input/output connectors
for
easy connection to radio equipment.
