Page 4: Features & Specs
FEATURES & SPECIFICATIONS FEATURES • Low harmonic content (below -43dBc on HF & -65dBc on VHF bands) thanks to an efficient Chebyshev filter. Fast and effective protection systems maintain the amplifier’s safety from operational damage. • • Compact linear amplifier design with (600 Watts) all mode. •... -
Page 5: Quick Start Guide
QUICK START GUIDE 1. Connect the Amplifier to a (48-53 VDC 25-A Source) 2. Connect the output of the Amplifier to a 50-ohm load or to the corresponding antenna. Connect the RF-IN of the amplifier to the RF-OUT of the transceiver. Never connect a Soft-Key 3. -
Page 6: Main Screen
MAIN SCREEN 1. FWD Power Meter: Indicates the output power in operation mode with high accuracy. Note: measurement sometimes will not match with an external instrument due to loss from coax cables loss or other devices connected to the transmission line. This loss can be up to 0.2 dBm. 2. - Page 7 10. OPR/STB: Disables/Enables the amp. The transceiver signal goes directly to the selected antenna when the button is in standby. Standby pass-through power max 100 Watts. 11. Tune Call: Internal Tuner will be ready to receive a 10-30 watts continuous carrier to start the auto adjustment.

SETTING SCREEN Main screen / Setup button Sound: Enables or disables the alarm sound. Note: The protections are not disabled. Input 10W: Select ON for the lowest input attenuator for 5-10 Watts drive, ideal for QRP Radios. Select OFF for higher power radios (40 watts MAX). For Safety, when rebooted the selection (Input 10w) will default to OFF. -
Page 9: Rear Panel
REAR PANEL 1. DC Power Input: DC input to feed the Amplifier, the optimum source is 52 VDC 25 Amps. Note that polarity reversal can cause severe damage to the amplifier. 2. SO239 RF Input: Do not exceed an input level of more than 40 Watts. 3. - Page 10 INTERNAL TUNER Internal Tuner Specifications: • Range: 3.5 to 54 Mhz • 600 Watts All modes • Matching Range 3:1 • Tuned 1.3:1 • Inductance 3.33 uH / Capacitance 310 pF • Minimum Tuner Lebel 10 Watts Good Practice. An antenna tuner allows for efficient power transfer by matching the impedance of the transmission line with that of the antenna.
