Would it qualify as CW if I whistled into my microphone and keyed and unkeyed to make dashes and dots? It would be so much easier than buying a bug.

(this is a joke, if I posted this in CW I am sure that I would be skinned alive)

And you wouldn't have to worry over comments about your "fist".  There WOULD be concern if your "lip" wasn't in good shape.  Your lung capacity would have to be pretty good!

I couldn't call it "CW" in any case... Wink

Why not? Continuous Whistle still abbreviates to "CW".

I think it's actually illegal below 50.1 MHz because it's MCW Grin  But wait, maybe it's just phone in a different language...

If you do it in the CW/digital sub-bands, you can't make the case that it's legal phone.  But you can at least try if you're operating in the phone subband.

Is this a type of Morse communication that you're ONLY allowed to use in the phone subbands on HF, not in the CW/digi ones?

I wonder if an OT (old timer) could get the dentures drilled with a flute hole between the two front teeth so breathing would just make a constant tone.

(BTW, getting close to being an OT myself so this is also a self-depreciating remark).

All kidding aside you can get a breath activated key.

Actually some mics can be used to send real cw by using the up/down keys. However that would be tough sending it that way. I know a guy who once sent cw using a mc-43 kenwood mic by using the p.t.t. switch on the mic. He did it just fine,but I felt sorry for that mic!................. Cheesy

I can actually see where that would be useful for amateur ops who have disabilities.

There was a "paddle" version in QST some time back for use with an electronic keyer.  Used some tubing, a tee, and a pair of switches, one activated by pressure and one activated by suction for dots and dashes.

Heh.. this thread blows...  Grin (humor)

I dont know about your rig(s) but when mine is in CW mode the mike doesent do much of anything  Wink

Here comes the boring HAM part of me...

Nope it aint Continuous Wave. It is just someone whistling into there mike modulating a 'phone' envelope.

It may be morse code but it aint CW  Cheesy

If you can whistle a single tone into a perfect SSB transmitter, it IS actually CW.   You would get a single radio frequency output.

But practically speaking, I think it's just impossible to get a modulated-CW signal using an audio oscillator and SSB transmitter that's as clean as a direct-to-RF CW signal.  Perhaps that's why we're not allowed to use MCW on the HF bands: shouldn't matter so much when signals are usually/always weak like on VHF and microwaves.

I'm glad to see we are finailly getting some serious discussion on this forum. 
Of course if you have a fast VOX you can just insert a bit of carrier and turn the transmit audio down and just dit  ditty dit dit into the mike and have near perfect CW or maybe put
a Pink Floyd CD on and see the other op could read that.
The possibilities are endless!!!!

Who makes the fastest VOX for full break-in QSK whistling? Ten-Tec, "The SSB Company"?

Ain't CW..... pulse modulated SSB..... and the "CW" would be 3Khz wide!
