The best Morse code straight keys

A straight key is the simplest instrument in radio: a sprung lever and a contact. That simplicity is why a good one lasts a century — and why a bad one teaches you bad timing. Four picks, one honest verdict each.

Best first key

Xiegu VK-5 Mini Straight Key

≈ $70

A compact CNC-aluminium straight key with silver-plated copper contacts and a standard 3.5 mm plug. Xiegu build it to pair with their own radios (G90, X6100, X6200, X5105, G106), but the 3.5 mm jack is universal — it will key anything that takes a straight key, including a PC interface for practice.

Pros

Machined metal base, not plastic
Silver-plated contacts
Standard 3.5 mm jack works with any rig

Cons

Small footprint means a light key — anchor it for heavy sending
Marketed for Xiegu rigs, so check your own connector

Best classic action

Kent KT-1 Hand Key

≈ $175 new

A heavy British-style key on a wooden base with a long lever arm and silky bearings. This is the key people imagine when they imagine Morse. Buy-it-once quality; spares available from Kent for decades.

Pros

Heavy base — never moves
Genuinely lovely action at slow and medium speed
Repairable, serviceable, heirloom-grade

Cons

Price, and US dealers list it as a special order with a long lead time
Long-arm style takes a different wrist technique than navy-style keys

Best American classic

Vibroplex Straight Key

≈ $190–230

The oldest name in keys, still made in the USA. Navy-style short-arm action on a heavy base. If the budget allows and you want one straight key for life with a brand that will outlive us all, this is it.

Pros

Superb fit and finish
Heavy enough to stay put
Holds resale value

Cons

Premium price for a beginner
Overkill if you'll move to paddles within a year

Best character per dollar

Military-surplus key (Czech / J-38 style)

≈ $25–60 used

Cold-war surplus keys — Czech army keys and American J-38s especially — are plentiful, robust, and full of history. Action quality varies key to key, so buy from a seller with photos of the actual unit.

Pros

Real history on your desk
Built to survive a war
Often cheaper than new plastic

Cons

Condition lottery
May need cleaning and contact polishing on arrival

Which key should you learn on?

This is the question most first-time buyers are really asking, and the honest answer starts with an awkward fact: the organised CW courses tell beginners not to start on a straight key.

CW Academy, run by CWops, lists the same equipment for all four of its course levels — a single- or dual-lever paddle, and a keyer with a sidetone or a radio with one built in — and states plainly that straight keys, bugs and cooties are not allowed for these courses.
"Learning Morse Effectively" by Bruce Prior, N7RR, hosted by the ARRL, puts it more bluntly still: skip the straight-key stage entirely. His reasoning is that hams rarely use straight keys today outside Straight Key Night, that the standard way to send by hand is a paddle with an electronic keyer, and that professional telegraphers who spent careers on straight keys often paid for it with repetitive strain injuries.

That is one side. The other is that the Straight Key Century Club — mechanical keys only: straight key, bug or cootie — had 31,424 members as of 17 September 2026, and ARRL's Straight Key Night fills the bands every New Year. A straight key is not a dead end. It is simply a different reason to be on the air.

So the choice follows the goal, not the price:

If your goal is…	Buy	Why
Learning to read Morse	Nothing yet	Copying is a listening skill, and no key helps you learn it. Start free with the Koch trainer, then check yourself on the speed test.
Getting on the air, or joining a CW class	Paddle + keyer	It is what the courses require and what most operators use. See the paddle guide; a radio with a built-in keyer and sidetone covers the keyer half.
SKCC, Straight Key Night, or the feel of the thing	Straight key	Every dit length is yours to get right, which is the appeal and the difficulty. Any key above will do it.
Finding out whether you enjoy sending at all	Cheapest honest key	A surplus key or the Xiegu above costs less than a night out, and plugs into a practice oscillator or a rig's key jack.

One practical warning if you buy a paddle: it does nothing on its own. A paddle needs a keyer to turn your left and right contacts into timed dits and dahs — either inside your radio, or a standalone keyer with a sidetone so you can hear yourself. A straight key has no such requirement, which is part of why it survives as a first purchase.

Our own view, for what it is worth: buy the key that matches the reason you want one. If that reason is "learn CW and get on the air this year", the courses are right and a paddle is the efficient buy. If it is "I have always wanted to send Morse on a proper key", buy the straight key and enjoy it — the timing you build on it is real, and SKCC will have you.

How to choose (60-second version)

Weight beats features. The single biggest difference between a frustrating key and a lovely one is whether it stays put on the desk. Heavy base, or screw/tape it down.
Adjustability matters more than materials. You want adjustable contact gap and spring tension. Tight gap + light spring for speed; wider + heavier while learning.
Straight key or paddle first? It depends on why you want one, and the CW courses have a clear preference — see which key to learn on above.
Don't buy two cheap keys. One cheap key to find out you love sending, then one good key for life, is the efficient path.

Whatever you key with, practice material is free: the random CW generator gives you realistic text and the timing calculator shows exactly how long your dits and dahs should be at any WPM.
