Your name or email address: My older 2KL I bought inand it is still on its original finals—which proves that moderation is a key ingredient. Normal air mail, 4 – 6 weeks, No tracking. The controller also switches taps on the inductor, and switches in fixed capacitors as needed for the sata frequency ranges. A power attenuator in the primary circuit of the input transformer or splitter stabilises the input load impedance and sets the 2s2c652 stage power gain as required by radio regulations.

Amp only works from 20 meters and up. The RF matching transformers used in solid-state PA stages are wound on rectangular “binocular” 2-hole ferrite cores. The PA stage is always push-pull; this minimises even-harmonic generation.


With the ALC correctly adjusted as per the amplifier manufacturer’s instructions, the exciter’s drive power control should be set just at the point where the amplifier delivers nominal power output, and no higher. At the amplifier’s rated output, 2scc2652 ALC voltage is typically -4V.

Solid-state amateur HF linear amplifiers generally fall into two power classes: The ALC voltage is usually negative-going; the higher the voltage, the lower the exciter output drive power. Normal air mail, weeks, No tracking.

The auto-tuner must be disengaged when using an external tuner. Bifilar or trifilar windings made with miniature coaxial cable are used. If you want to know the exact Adta, Pls contact us before you bid. Normal air mail, 3 – 6 weeks, No tracking. At a minimum, these should include the following:.

Principle of amplification

But here also there is a problem in the cross-over region that creates a distortion at the time of alternation is changing. Rest of the World. Crossover distortion is significant 2sc26522 low drive levels. The PSU should incorporate an adequate forced-air cooling system. Let us start here, at the heart of the amplifier. The most cost-effective designs employ multiple devices rated at W to W output each.

There is two 2kls listed on Ebay.

If we datw to amplify this signal to higher values because the station if far away, we want that our amplified signal be strictly identical in shape to the original, only its intensity must have increased.


The auto-tuner is not intended to match highly reactive loads, such as non-resonant antennas; a suitable external tuner can be connected to the amplifier output for this purpose.

Icom Ic 2kl Amplifier

In some amplifier designs, an additional attenuator is switched in to reduce unwanted RF output during the auto-tuner tuning cycle. N8YXSep 2, The PSU incorporates inrush-current limiting. The combiner output is fed to a bank of bandswitched low-pass filters LPF.

Scott at Mts is putting in icom parts in the LPF board. With a higher amplifier power gain, the lower drive requirement goes along with better exciter linearity. I emailed him asking if they ran as with per Icom specs.

Many solid-state amplifiers offer dual RF input, keying and ALC interfaces, allowing the operator to switch between two exciters. Extending this principle further, a tube amplifier, with its peak plate-voltage excursion of thousands vs.
