Just to mention a further alternative, independent from propagation conditions:

iCW - Internet CW.

I know of two Mumble CW servers, one in the U.S.A. and one in Germany.


Access is free.

A group of several OPs may meet in a single "CW room".

Mumble is a low latency VOIP platform, so well suited for full-duplex CW.

You'll need two sound cards, one for the audio input, one for the audio output of Mumble.
You may use the side tone of your transceiver or some kind of code practice oscillator for
the audio input of your CW. I have been using an USB headset (sound card built-in) for the
receiving path; the internal sound card of the PC for the sending path.

Activity on these servers is very low -- so SKEDs are the best (only) way to have a conversation.
SonoBus is an alternative to Mumble.
