A radio preset gives the transmitter the character of a class of real equipment: how clean the signal is, how much power is available, how hard the amplifier compresses, how much hum and phase noise are present. Selecting a preset overwrites the power field and all [[Advanced Transmitter Settings]]; individual values can be edited afterwards.

Presets are simulation starting points that represent classes of equipment, not measured laboratory profiles of specific radios.

== Preset list ==
{| class="wikitable"
! Preset !! Power (W) !! Character
|-
| Generic HF transceiver || 100 || Neutral modern transceiver, the default starting point.
|-
| Clean lab exciter || 10 || Near-ideal signal source: no compression, very low noise, excellent carrier and sideband suppression. Useful as a reference.
|-
| Icom IC-7300 class HF rig || 100 || Clean modern SDR-based 100 W transceiver.
|-
| Icom IC-705 class QRP SDR || 10 || Clean low-power portable SDR.
|-
| Icom IC-7610 class base SDR || 100 || High-end base station, very clean output.
|-
| Yaesu FTDX10 class HF SDR || 100 || Modern hybrid SDR transceiver.
|-
| Elecraft KX2/KX3 class QRP || 10 || High-quality low-power portable.
|-
| Yaesu FT-817/818 class QRP || 5 || Older portable design: modest headroom, more compression and hum.
|-
| Kenwood TS-590 class HF rig || 100 || Clean conventional 100 W transceiver.
|-
| Xiegu G90 class portable HF || 20 || Budget portable: audible compression and a rougher signal.
|-
| (tr)uSDX / uSDX QRP Class-E || 5 || Minimalist kit radio: heavy compression, significant distortion and drift artifacts.
|-
| Rugged HF manpack || 20 || Military-style manpack: robust but not clean.
|-
| Vintage tube SSB || 100 || Tube-era transmitter: soft compression, hum, slow keying.
|-
| Collins KWM-2 class tube SSB || 100 || Classic tube SSB station.
|-
| Vintage AM boatanchor || 50 || Full-carrier AM transmitter with strong hum and character. High modulation index.
|-
| Overdriven export AM/SSB || 25 || Deliberately dirty CB-style export radio: overmodulation, splatter, poor suppression.
|-
| Budget VHF/UHF handheld FM || 5 || Inexpensive FM handheld.
|-
| Homebrew Class-E AM || 10 || Home-built high-efficiency AM rig, full modulation.
|-
| Overdriven driver / poor ALC || 25 || Worst-case example: extreme drive, minimal headroom, heavy distortion and noise.

== Choosing a preset ==
* For intelligibility tests and clean comparisons, use '''Clean lab exciter'''.
* For realistic amateur operation, pick a preset in the class of radio being simulated; the 100 W transceiver presets behave similarly with small differences in compression and noise.
* The dirty presets ('''Overdriven export AM/SSB''', '''Overdriven driver / poor ALC''', '''(tr)uSDX''') are useful for practising recognition of poor signals on a receiver.

Low-headroom, high-drive presets heat the amplifier faster at a given power, see [[Power Amplifier Behaviour]].
