A Morse code key is a hand-held switch. That's it. So why do prices run from about $25 for a used army-surplus key to over $300 for a new bug? Because every key is also a physical interface you'll spend hundreds of hours holding, and the right one depends on what you want to do with it.
This is a vendor-neutral first-time buyer's guide. Some links on our gear pages are affiliate links (see the disclosure), but this guide names products only where we have checked them, and every price below was read from a seller in September–October 2026.
Step 1: Decide what you want the key for
The honest first question isn't your speed. It's your goal:
| Your goal | What to buy first |
|---|---|
| Learning to read Morse | Nothing yet. Copying is a listening skill; start with the Koch trainer. |
| Getting on the air, or joining a CW class | A paddle, plus a keyer (many HF radios have one built in). |
| Straight Key Night, SKCC, or the feel of hand-sent Morse | A straight key. |
That middle row surprises people who expect to "start on a straight key". The organised courses say otherwise: CW Academy requires a single- or dual-lever paddle and a keyer with sidetone for all four of its course levels and does not allow straight keys, bugs or cooties. Bruce Prior, N7RR, in Learning Morse Effectively (hosted by the ARRL), advises skipping the straight-key stage entirely. The full reasoning, and the case for a straight key, is in which key should you learn on.
Step 2: Pick a key family
Straight key
One lever, pressed down to send a tone and released to stop. Every dot and dash is timed entirely by your hand, which is both the appeal and the difficulty. It is the key of Straight Key Night and of the Straight Key Century Club.
Best for: hand-sent CW for its own sake, and anyone who simply wants one on the desk. Not accepted in CW Academy classes.
Single-lever paddle
A paddle has two contacts; a keyer, usually built into the radio, turns them into perfectly timed dots (one side) and dashes (the other). A single-lever paddle moves left or right but never both at once, so each element is a separate movement.
Best for: a first paddle if you want the simplest motion.
Iambic (dual-lever) paddle
Two independent levers you can squeeze together; the keyer then alternates dots and dashes, which saves movements on letters like C (-·-·) and Q (--·-). Keyers offer two squeeze modes, A and B, which differ in how they finish an element after you release.
Best for: most operators sooner or later. A mistimed squeeze inserts an extra element, so expect a short adjustment period.
Bug (semi-automatic key)
A mechanical key patented in 1904 by Horace G. Martin and first sold by the Vibroplex company in 1905. A weighted lever vibrates to make a run of dots; dashes are made by hand. The Vibroplex shape is the classic.
Best for: style and history. Catch: a steep learning curve, and the dot speed is set mechanically by the weight's position.
Sideswiper / cootie
A single lever swept side to side rather than pressed down; every element is made by hand. SKCC counts it as one of the three mechanical key types alongside the straight key and the bug.
Best for: personality. Not a first key.
Step 3: Set a budget by tier
| Tier | Price range | Examples (price checked at a seller) |
|---|---|---|
| Starter | about $30–80 | Used J-38 military-surplus straight key (most sell for $30–70 on eBay); Xiegu VK-5 straight key (about $76); Putikeeg mini dual paddle (about $46). |
| Mid | about $165–230 | Kent TP1 twin paddle (about $165) and KT-1 hand key (about $175); Bencher BY-1 paddle (about $170–190); Vibroplex straight key (about $190–230); Bencher BY-2 paddle (about $230). |
| Premium | about $300 and up | Vibroplex Original Deluxe bug (about $310), and hand-made paddles from specialist makers. |
Don't skip ahead. A premium key won't make a beginner faster; the bottleneck is the operator's rhythm, not the hardware. Buy the cheaper key, learn on it, and upgrade when the gear is genuinely the limit. Current prices and links for each of these are on the straight key and paddle guides.
Step 4: Inspect the build
What separates a $50 key from a $200 one:
- A key that stays put. A light key slides on the desk and wrecks your rhythm. Heavy bases solve it; for a light key, a non-slip pad, putty or a steel plate does the same job.
- Adjustable spring tension. How firmly the lever returns. Lighter feels more responsive; heavier is more forgiving.
- Adjustable contact gap. How far the lever travels. A wide gap is slower; a narrow one is faster but easier to chatter.
- Serviceable contacts. Contacts wear and tarnish over the years. Keys whose contacts can be cleaned or replaced last for decades.
- Metal construction. A metal frame keeps its adjustments; a flexing plastic one drifts.
Step 5: Confirm the cable and connector
Modern keys usually come with a 3.5 mm or 1/4-inch (6.35 mm) plug. Older transmitters may use binding posts or other connectors. Check your radio's KEY input before ordering: the wrong plug means an adapter and one more thing to fail.
Step 6: Buy from a reputable source
- The maker. Vibroplex, Kent and Begali sell direct.
- Established ham retailers. In the US, DX Engineering, Ham Radio Outlet and GigaParts; in the UK, Waters & Stanton. They hold real stock and take returns.
- The used market. ARRL eClassifieds and the QRZ.com swapmeet (a free account is needed) for keys from other amateurs; eBay for military surplus, where you should buy from a seller with photos of the actual key.
Avoid listings with no model number, no maker's name, or photos that look like a different key. The price is always too good to be true.
Step 7: Try before you commit to a style
If you can, try someone else's key. Hamfests often have keys on demo tables, and most CW operators at a club meeting will happily let a visitor send on theirs. A paddle that is perfect in one hand can feel wrong in another, and paddle preference is personal.
Step 8: Upgrade only when the gear is the limit
The honest test: can the key send cleaner Morse than I can? If it can, you don't need a new key; you need more practice. A good mid-tier key lasts many years, and premium keys make most sense once you know exactly what feel you prefer.
What to skip on a first key
- "Adjustable everything" gimmicks. Spring tension and contact gap are what matter; more adjustments just add drift.
- A paddle with its own keyer if your radio already has one. Check your radio's manual first; many HF transceivers have one built in.
- Decorative novelty keys. Fun gifts, poor primary keys.
The one-line summary
Learn to copy first; then buy the key that matches your goal. For classes and getting on the air, that is a paddle; for Straight Key Night and SKCC, a straight key.
When you're ready to send, the keyer trainer scores your timing against a target speed, the translator plays any text at your target speed for comparison, and the speed test measures how fast you copy.
