It depends on a number of factors. Here in the Colonies, our beloved
version of OFCOM has defined three types of unlicensed radiators:
Incidental, Unintentional, and Intentional. Incidental are those that
make RF as part of their operation but don't need to and it serves no
purpose in their
Wayne was looking for 1mW output. How does that equate in regard to the regs?

If they're unlicensed, they will be intentional radiators subject to
47CFR15 Subpart C [15.201 et seq] which imposes field strength limits
that vary with frequency. 15.201(b) may also require certification.
Depending on choice of frequency, 150 mW may be way too high since in
the 1.7 - 30 MHz
Thanks, Dave.
I've had many responses to this request. Excellent response from a community
that not only wants to help kids, they also want more CW ops on the air :)

1) Wouldn't it be better to use one of the ISM bands? Then licensing is not
a problem. I'd feel uncomfortable giving radios that operate in the ham
bands to people without a license. There are bands 6.765-6.795MHz,
13.553
You could use most of the circuitry of the SMK-1 40m QRP rig to do exactly what
you describe Wayne (leave off the PA!). The SMK-1 has Full break-in, no clicks
or chirps, and a half-decent receiver in it. Feel free to use the design as you
see fit.

Y'all wanna talk Super LP CW with a kit builder, contact Floyd Hoskins,
N5FH. He's seen, fixed, built, et al. many different designs.

Hi all,
Someone recently told me that he'd benefitted throughout his life from learning
Morse code as a teen. Ham radio helped him cope. He's gone on to promote Morse
because it can help kids with certain cognitive or social issues. Such problems
are exacerbated by social media, these days. We
