I used to wonder why amplifiers were sometimes called "tortoises" in amateur radio.
"CQ-8, as Ham called it, likely originated in Taiwan. In the 1980s, when Taiwanese ham radio operators began to emerge, their equipment often consisted of a handheld transceiver with strong signal requests," Ham continued. "Then I added an 'XX watt' 'mushroom,' which is a Taiwanese pronunciation of 'turtle.' So why call it a 'mushroom'? The Japanese-made power amplifiers that were imported at the time had large print on the packaging: 'POWER BOOSTER'. Soon, 'POWER BOOSTER' was shortened to 'mushroom.'"
I always found this claim to be strange. I then searched online again and found another explanation.
In amateur radio, a power amplifier is a device that is installed at the output end of a transmitter to amplify its power. It is also known as an amplifier or a linear amplifier, and it is used to increase the transmission power. These amplifiers typically have a stable structure or are surrounded by large heat sinks, making them relatively heavy. This has led some people to associate them with turtles, hence their name.
I also find that this statement seems difficult to accept for some people.
Today, when I searched again and found the following statement, I believe it could be used as additional information. (Source: deepseek)
In the field of amateur radio,The nickname "Turtle" specifically refers to high-power linear power amplifiers.This is a very vivid and historically rich "slang," primarily due to the following reasons:
1. Figurative comparison: Appearance versus action
Bulky exterior: Many large tube amplifiers, both in the early days and today, have a large, heavy, metal chassis or heat sink that resembles a turtle's shell.
Slow "warm-up": Vacuum tube amplifiers (especially high-power ones) require tens of seconds, or even longer, for the vacuum tubes to heat up before they can enter their operational state. This waiting period is humorously described as "the turtle slowly extending its neck."
"Increasing power"Unlike transistors, which can switch on and off instantly, vacuum tubes have a power that gradually increases, which also aligns with the characteristic movements of turtles.
2. Key Features: Stability and Load Capacity
"Weak signal on the back": The function of a power amplifier is to take the relatively small power output from a radio (referred to as the "host") – for example, a few watts to one hundred watts – and amplify it to several hundred or even thousands of watts before transmitting it. This image of "carrying and amplifying," is similar to an turtle carrying a heavy load while moving forward.
"Slow but powerful"It doesn't change the signal content (linear amplification), but simply provides a powerful "push," allowing the signal to travel further. This stable, solid characteristic, which provides fundamental strength, also aligns with the symbolic meaning of the turtle.
3. The evolution of language and culture
The influence of English slang: In English, "big power amplifiers" have long been referred to as "Linear Amplifier"Or simply call "Amplifier", while "kilowatt-class amplifiers" are sometimes colloquially referred to as "Kilowatt Turtle"It's called "turtle shell" because it provides a very robust power supply, similar to the hard shell of a turtle. This term has been adopted into Chinese usage through international communication.
Corresponding to "host": A radio transceiver is sometimes also referred to asKitty (Rig)Because it is agile and emits "weak" signals, the device that amplifies this small signal into something enormous naturally corresponds to a slow but powerful animal – the "turtle." This combination of "cat" and "turtle" is widely known among enthusiasts.
Summary and Extension
So, when the ham says..."Open the turtle", which means"Power amplifier connection"This term is full of self-deprecating humor, wit, and the cultural characteristics of amateur radio enthusiasts and tech geeks.
Important Note:
Although the name is interesting, but"The 'Turtle' is a very serious and high-risk device. It involves extremely high voltages, large currents, and strong radio frequency radiation.。 When using a power amplifier, the following must be observed:
- Ensure that the antenna system (including cables, baluns, and the antenna itself) can handle high power levels.
- Ensure good grounding and heat dissipation.
- Strictly adhere to safety operating procedures.To avoid RF burns or electric shock.
- Legal use: Ensure that your operating license level allows for high power operation, and operate within the specified frequency bands and power limits.。
Therefore, "the turtle" is not only a symbol of strength but also represents significant responsibility and strict safety requirements. It's a powerful companion that can help your signal travel across mountains and rivers, but it must be handled with care.
