SPE 2K AT

The most technologically advanced in the world
Two powerfull CPUs are used.
Over 35,000 lines of software for performance that cannot be found in any other amplifier.

Fully Automatic
Easy connection with all models "ICOM, YAESU, KENWOOD, TEN-TEC, FlexRadio ELECRAFT" for immediate management of the bands, tuner and antennas.
Same performance with all makes or homemade rigs.
The operator has only to move the “Frequency Tuning Knob” in the transceiver!

Wide frequency coverage
1.8 MHz to 50 MHz including WARC bands.

Fully solid state
Up to 2 KW pep SSB, CW out; 50 MHz included.
MAX / MID (1KW) / LOW (500W) power selected according to the operator SSB/CW power requirement, for digital modes and for linear protection (automatic).
No heating time, immediately ready!
Virtually limitless life of the amplification devices ((6 MOSFETs MRF151G).

Automatic Antenna Tuner built-in
Capable of matching 3:1 SWR on HF, and 2.5:1 SWR on 6 meters.
Capable of programmable switching of 6 antennas (SO239 connectors).
Up to 3 antennas for the same band.
Management of the SteppIR / Ultrabeam antennas (tuneable).
Measure also the SWR of the antenna / cable system.
Bands, Antennas, Tuning conditions are changed in 10 msec.
Bands, Antennas and Tuning conditions are managed also in “STBY“ to support the exciter only.
Max. attenuation 0.8 dB.
Bypass capability.
Remotable (option).

SO2R

Two inputs available.
SO239 connectors.

High power gain (up to 14.5 dB).
In “OPERATE“ the required drive power is automatically set with an ALC connection and in “STANDBY“ the exciter is then automatically reset to full power.

Very clean and low distortion output!
Spurious emissions less than -60 dB ( 50 MHz –65 dB ).
3rd order distortion (two tone test) 36 dB typ.

Input 50 ohm always perfectly matched
SWR less than 1.2:1.

Fully protected
Temperature, Over-Voltage, Over-Current, SWR, Reflected Power, Max RF Tuner Voltage, Over-Drive, Amp. The correct parameters are continuously monitored.
The same protection is realized in two different ways:
· Via hardware circuits (HW) to assure great speed.
· Via the software (SW), to assure great accuracy.
Thanks to the SW, transmit relay changeover is carried out with zero current at the contacts.

Full break-in operation (QSK)

Quiet operation.
Linear management of the speed of the cooling fans of the heatsink.
In the power supply, fans speed is reduced during the reception.
Since, considering the big power developed, a significant amount of heat must be removed, every precaution is used to keep the lowest possible the noise of the fans.

Continuous use
“MAX” mode: SSB / CW unlimited.
Automatically switches to “MID” for a while if, in “MAX”, a continuous signal (RTTY) is transmitted.
“MID” “LOW” modes, RTTY unlimited.

Switching power supply.
Continous input between 190 – 255 Vac, 47-63 Hz.
PFC (Power Factor Correction).

The linear can be switched ON / OFF also switching ON / OFF the exciter.

Fully remotable.

With a large LCD display is possible to have a great deal of information
W pep out, V pa, I pa, W, Power gain, Temperatures, SWR (after and before the ATU), Input setting, CAT setting, Band and other indications including an alarms log.

Easy to operate
Powerful SW gives you a user-friendly unit.

USB port.
For remote control.
For new SW releases download.

Easy transportation
A sturdy carry-bag is supplied for “QSY, FIELD DAY, DX’ PEDITIONS etc.“.

Certifications
CE, FCC.
