HL-1.1Kfx HF Amplifier Features:
Description: The HL-1.1Kfx is a light weight HF amplifier. At the time it was the lightest 600W – 160m-10m HF amplifier on the market, with a total weight of only 22.5 Lbs! This amplifier has been designed for the traveling operator such as, DXpeditions, vacations, field day, camping, and for persons who simply want a light weight amplifier. The unit has a carrying handle and an additional set of mounting feet on the left side of the case, so that the amplifier can sit vertically or horizontally. It can be stored in a carry-on briefcase and can easily fit in an overhead compartment on an airliner. The HL-1.1Kfx incorporates an internal switching power supply that can be plugged into any line voltage source throughout the world, making the amplifier a natural for very remote locations. No adjustments are necessary when switching from different line voltages. The amplifier incorporates four THP 2933 RF Mosfets which are used in the HL-1.5Kfx. The switching power supply, feeds the Mosfets with a slightly lower voltage than the 1.2Kfx, resulting in an output power of 600W Max SSB PEP, 600W CW and 400W RTTY on HF. With the exception of the slightly lower output power and its lighter weight, the features of the HL 1.1Kfx are nearly identical to that of the 1.2Kfx. The amplifiers broadband tuning characteristics require no further tuning once the proper band has been selected. The HL- 1.1Kfx utilizes manual band switching; the operator must select the proper band with every band change. The unique air cooling duct design incorporates an efficient powerful blower fan which supplies cooling to the Aluminum Block heat sink located atop the Power Amplifier module. The fan also supplies cooling to the other internal components of the amplifier. Its quiet operation allows for even the weakest signals to be heard. The amplifier uses a sophisticated circuit containing an advanced 16 bit microprocessor to control the normal functions of the amplifier along with the various high speed protection circuits, which will protect the amplifier from faults such as Overdrive and High SWR. There is a front mounted meter. The meter’s function is selectable via the front mounted meter switch. It can display Power Reflected (Pr), Power Forward (Pf), Idle voltage to the MosFets (Vd), and Transmitting Current of the MosFets (Id). Mount to the right of the meter switch is the manual rotary band switch which the operator would use to select the appropriate band. There are also numerous LED indicators mounted on the front panel, Power On, High Current (Id). Warning lights include Over Drive, Overheat, Over Volt, Internal Fuse Open, and Excessive Reflective Power. Rear controls include ALC adjustment control, Transmitter input, Antenna output, PTT keying line (STBY) RCA jack and an ALC Input RCA jack. The amplifier is QSK capable (50wpm+) using miniature high speed Panasonic relays for T/R switching |
