- Page 2 1. Introduction Thank you for purchasing the HL-2.5KFX. This compact and lightweight desktop HF linear power amplifier has a maximum input power of 2.9 kW. Our solid-state broadband power amp technology makes it the smallest and lightest in the industry.
- Page 3 inserted at both ends of the remote control cable, ALC cable, coaxial jumper cable, and antenna cables, as needed. Also, a common mode AC line filter (near the AC outlet), and in-line low pass filters on the antenna coaxial cable, (as necessary), are recommended.
- Page 4 MUST be shipped using the original box and packaging materials. 3. Features 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.

Instruction Manual x 1 Optional Items Auto Antenna Tuner (HC-1.5KAT) 5. AC Line Voltage The amplifier is designed to work with AC 240 V (200- 250 V). The correct AC plug (not included in the package), must be obtained locally due to the AC plug variations worldwide. The AC voltage has been factory preset for 240 V use (or as requested by the customer at the time of order). -

8. Operation ***CAUTION: Under the Manual Band Set operation, always be sure to check if BAND Switch position matches that of your radio before keying PTT or the CW paddle. Also when you have changed the BAND, do not make the full power CW (carrier) drive but reduced level power to see if the BAND is set correctly and the amplified RF power comes out properly. - Page 15 How to Operate 8-2-1 Connect AC cord and coax cables as illustrated in Section 7 Connection. Connect the cable from “SEND” to ACC or the remote terminals of transceiver, where it is marked “SEND” or “TX GND”. These terminal pins are shorted to ground when the transceiver is in TX/ON AIR mode.

8-2-5 You can now increase the drive level to nearly 80-90W to achieve maximum carrier output power of 1.4 kW (CW, RTTY) from the amplifier. If you change to SSB mode, peak voice power will reach approximately 1.5 kW. For high duty cycle transmissions like RTTY, SSTV, or FM modes, it is recommended you reduce the drive power by 20-30 % compared with SSB/CW. - Page 17 always need to connect ALC to the transceiver, if you set the mic gain properly and do not overdrive the amplifier. Depending upon the manufacturer of the transceiver, the suitable ALC voltage differs. ICOM may need 0~-4 V, and Yaesu may need 0~-5 V range..

- Page 21 11-2 Safety Circuits In addition to the protection circuits above, there are other safety circuits (inter-locked circuits) built in th e amplifier. They directly shut down AC power line for the primary of the power transformer, and if shut down, AC power lamp (green), LCD display and cooling fan will all go off.
