2-13
For long continuous operation in RTTY/FM modes, it is recommended
you reduce the RF drive levels by 20% to 30% lower output than CW/SSB
modes.
2-14 To prevent damage to the precision electronic components, avoid
extreme physical shock to the amplifier. If factory service is required, the
amplifier
MUST
be shipped using the original box and packaging materials.
3. Features
3-1
Our solid-state broadband design engineers worked to make the
HL-2.5KFX, the lightest and most compact 1.5 kW HF amplifier in the industry.
This world-class compact 1.5 kW HF amplifier is the easiest to handle and
operate.
3-2
The amplifier is equipped with a newly developed band decoder. The
amplifier’s decoder changes bands automatically as the data signal is received
from the associated HF transceiver’s frequency bands.
3-3
The amplifier’s main PA section includes 2 high power MOS FET
ARF1500’s by Microsemi, resulting in 1.5 kW PEP (SSB max.). The amplifier’s
broadband characteristics require no further tuning once the operating band is
selected.
3-4
The amplifier allows operation in full break-in CW mode due to the use of
the amplifier’s high- speed antenna relays (made by Panasonic/Matsushita).
3-5
With the unique duct structure design and the powerful blower fan, the
aluminum heat sink block for RF PA module (and other components), are
effectively cooled. The fan’s quiet operation allows for even the weakest DX
signals to be heard.
3-6
The amp utilizes an advanced 16 bit MPU (microprocessor) to run the
various high speed protection circuits such as overdrive, high antenna SWR, DC
overvoltage, band miss-set etc.
