Maintenance Features

The KLV 350 is a linear amplifier designed for base station use, specifically for users who require high power for long and very long-distance radio connections. Its primary function is to amplify radio frequency (RF) signals, enabling more robust and extended communication.

Function Description:

The KLV 350 operates as a linear amplifier, taking an input RF signal from a transceiver and boosting its power for transmission. It supports various transmission modes, including AM (Amplitude Modulation), FM (Frequency Modulation), SSB (Single Sideband), and CW (Continuous Wave). The amplifier incorporates a fan for forced cooling of the internal tube, allowing for more intensive and prolonged use without overheating.

Key controls and indicators include:

Network Switch (1): A general power switch for turning the unit ON or OFF.
Linear Amplifier Switch (2): Engages or disengages the linear amplifier function (ON/St.By).
Transmission Mode Selection Switch (3): Allows selection of the appropriate mode (AM for AM/FM, SSB for SSB/CW).
Output Power Selector (4): Adjusts the amplification level, offering two power levels. The "HI" (maximum) level is recommended for short connections.
Output Arrangement Variable Capacitor (TUNE) (5): Used for tuning the amplifier to achieve maximum output power.
Output Power Wattmeter (6): Displays the output power in watts.
Modulation and Power Light Indicator (7): Illuminates to indicate power and modulates with the signal.

Important Technical Specifications:

Frequency Range: 26 - 30 MHz
Power Supply: 230 V AC ± 10%
Input Energy Consumption: 2.5 A
Input Power:
- AM - FM: 1 - 10 W
- SSB - CW: 2 - 20 W
Output Power:
- AM - FM: 100 - 200 W
- SSB - CW: 200 - 400 W
Input SWR (ROS ingresso): 1.1 / 1.5
Operation Modes: AM, FM, SSB, CW
Fuse: 3 A (on the net)
Tubes Used: 2 x EL 509 or EL 519

The device is certified to comply with the EC Certificate of Conformity (EMC Directive 89/336/EEC), adhering to European Telecommunications Standards ETS 300 684 and 300 339 (December 1995).

Usage Features:

Installation:

After unpacking, inspect the amplifier for any transport damage.
Connect the transceiver to the SO239 connector labeled "RTX" on the amplifier's rear panel using a 90 cm RG58 extension cable.
Connect the antenna to the "ANT" connector, also on the rear panel.
Ensure the network switch (1) is in the "OFF" position.
Connect the power cable to a suitable outlet, avoiding reducers or adapters.
Position the amplifier to allow easy access to all controls and ensure sufficient free space around it for proper ventilation.

Operation:

Turn on the amplifier using the network switch (1) to "ON."
Allow at least two minutes for the tube to warm up before use.
Select the desired output power level using the selector (4). For short connections, the "HI" (maximum) level is recommended.
Engage the linear amplifier using switch (2) to "ON."
Select the appropriate transmission mode with switch (3): "AM" for AM/FM, "SSB" for SSB/CW.
The Wattmeter (6) will display the output power, and the indicator (7) will illuminate and modulate with the signal.

Tuning (Crucial for optimal performance and tube longevity):

Before making radio connections, the amplifier must be tuned using the TUNE control (5).
Set switch (2) to "ON."
Transmit a signal from your transceiver.
Adjust the TUNE control (5) to achieve maximum power reading on the Wattmeter (6).
During tuning, transmit for no more than 2-3 seconds, with 5-10 second intervals for cooling.
Re-check tuning whenever the channel, frequency, or position of control (4) is changed.

Important Usage Notes:

Always disconnect the network plug before opening the amplifier for any maintenance or repair (e.g., fuse replacement).
For any problems, consult specialized technicians.
To prevent overheating and tube damage, use antennas and cables rated for at least 600 W with an SWR not exceeding 1.5 at maximum power.
Use the amplifier for long-distance connections only. Avoid continuous transmissions longer than 5 minutes without reasonable breaks to allow the tube to cool.

Maintenance Features:

Warranty: The device comes with a 24-month warranty from the date of receipt.
Warranty Exclusions: The warranty does not cover external and aesthetic parts, nor the tubes.
Compliance: The manufacturer emphasizes that the use of linear amplifiers is subject to specific laws in each country. Users are advised to be aware of and comply with these regulations. The manufacturer disclaims any responsibility for incorrect use or non-compliance with applicable rules.
Voiding Warranty: Failure to observe the instructions provided will void the warranty.

The KLV 350 is designed for robust performance in demanding radio communication scenarios, offering high power output and user-friendly controls, provided the tuning and operational guidelines are strictly followed. Its internal cooling system allows for more intensive use compared to amplifiers without forced cooling.
