W4/VP9KF - CW Links
Completely (!?) accepted definition of QRP (at least by all of the QRP clubs I can find):
CW <5W, SSB <10W (including 'SSB' driven datamodes like FT8, etc.)

Speed Telegraphy (Wikipedia)
It was once feared that 'scrapping the morse test' would 'do in' both
the HF bands and CW. This has proven, on the whole, to not be the case.
However, one thing that has changed is the limiting of CW to smaller
and smaller recommended segments of the bands, instead of the regime
where CW could go anywhere. This is definitely a step backwards.
However, good break-in QSK CW is more at threat because of the next generation of rigs.
The Flex and Anan (Apache Labs) SDR radios have some pretty awful
turnaround times on CW. This
appears to be because of the vast strings sent over the API interface
between external control (PC or 'panel') and the 'radio'. This latency
needs to be addressed in other new rigs before degradation is allowed
to go too far. There should be absolutely no reason why CW at 30wpm+
should tax the interface of either the computer inside the rig or any
that are external, provided the API is thought out properly. Before
it's too late you should e-mail manufacturers and
make sure that CW isn't defeated by digital (SLOW!) modes. The horse
has bolted on some of these; Flex, Apache, while some others may be
saved before they finalise their architecture, notably Elecraft's K4.
Others, such as IC7610, IC7300 and Expert MB-1 are 'out there' but I don't personally know how they perform.
We can now add: SunSDR2 DX, Elad Duo-X, more coming......

Morse Practice (Online)
at callsigns: 44wpm and
approaching my on-air [noisy] rate of 48wpm)
Zoom and Skype are used
for one-on-one tutorials by some groups

Different keying methods
It's pretty hard to find "one key does all".
Simple Oscillators (CPO): Kent
kit, 555 oscillator diagram, K1EL
Code Practice Oscillator kit,
G0TDJ osc. Breadboard Radio Pacific Antenna
Super Simple CPO [this is great - made one of my own with 2N3904. Worked first time. All junk box components, cost $0] Phoenix NT7S circuit
A seriously clean Oscillator: KF7CX circuit (based on Smooth Tone Osc). Also Twin T CPO.
More complex trainers: Morserino,
Morse Tutor/Keyer kit, MFJ
(various, quite expen$ive), Arduino CW Trainer N4TL (simplified)
With USB interface: Mortty nanoKeyer (+Arduino Nano v3.0/FTDI) K3NG
info TinyKeyer K1EL
Open CW Keyer (hamshop.cz) Funtronics K3NG
No USB interface: Ultra PicoKeyer PicoKeyer Plus Logikey 4SQRP OZ1JHM Accu Arduino Tortukeyer N1KSN PIC Phoenix
More: Microham Mtechnologies
Press MFJ QRPworks
Bugs, Sideswipers and Paddles
Quite a few make their own keys (here are some [W6FIF, NA6O, NV1Q & WB2LQF]). Many go on to be on sale.

Interesting? 'Minority' interest clubs dominate - *Straight key and QRP.
*Paid-for clubs are held back - notably CWops. *Speed, size or other limitation.
