1.8 MHz ~ 54 MHz (160m ~ 6m)
Detailed Views and Specifications
HL-2Kfx HF Amplifier

  • Covers all HF bands including 6m

  • Dual Antenna outputs

  • Built in Linear Power Supply
    With Transformer Taps for 100-230v 50/60Hz

  • Fairly Compact but Heavy

  • Dual cooling Fans

  • Amplifier incorporates built in protection circuitry for Over drive, over voltage, over heat and combiner mismatch.
  • Lower cost in replacing finals compared to replacing tubes in tube-type amplifiers.


The HL-2Kfx was the predecessor to the HL-1.5Kfx. It is 1Kw PEP Amp like the 1.5kfx with 6m included but lacked the the auto band changing ability that was added to the 1.5kfx and it used dual PA boards that were combined unlike the single PA board redesign used in the 1.5kfx. For its time the 2kfx was an extremely compact amplifier but was never sold in great quantity and is therefore fairly rare.
