while everything you are sending is shown in regular characters.
Another feature is worth mentioning here: The frequency of the tone you are hearing when you are
receiving the other station is adjusted through the "Pitch" parameter, as in the other modi. The pitch of the
tone when you are sending can be the same, or a half tone higher or lower then the receiving tone - this is
being set through the Tone Shift parameter, in the same way as in Echo Trainer modus.
One other thing you might want to know: the LoRa CW Transceiver does not work like a CW transceiver on
shortwave, where an unmodulated carrier is being keyed, and the delay between sender and receiver is just
defined by the delay in the path of the electromagnetic waves carrying the signals. LoRa uses a spread
spectrum technology to send data packets - in a way a bit similar to WiFi that you use on your phone or PC.
Therefore all you are keying in is being encoded into data first - esentially the speed and all the dots,
dashes and pauses between characters. As soon as the pause is long enough to be recognized as a pause
between words (as a blank space, as it were), the whole data packet assembled so far is being transmitted
and in due course being played back at the indicated speed by the receiving Morserino-32.
When morse code is packed into a LoRa data packet, dots, dashes and pasues are encoded; it is not so
that the clear text would be sent as ASCII cgaracters. Therefore it is possible to send "illegal" morse code
characters, or characters that might only be used in certain languages. They will be transmitted correctly
(but shown on the display as non-decodable)-
Sending the code word by word means there is a significant delay between sender and receiver, and the
delay depends to a large degree on the length of the words being sent, and on the speed that is being
used. As most words in a typical CW conversation are rather short (7 characters or more already
constitutes a very long word), this is nothing to worry about (unless you are sitting both in the same room
using no headphones - then it will be really confusing). But try sending really long words, say 10 or more
character long, at really low speed (5 WpM), and you will see what I am talking about!
The status line is slightly different from the other modi. First of all, the rotary encoder is always in the
volume setting mode - speed is determined from the decoded Morse code and cannot be set manually.
Pressing the encoder button will end the decoder modus and bring you back to the Start Menu.
On the left of the status display at the top, you will see a black rectangle whenever the key is pressed (or a
750 Hz tone detected - this replaces the indicators for external paddles and for the keyer mode.
The current speed as detected by the decoder is displayed as WpM on the status line. Whenever you leave
the decoder, this speed setting is preserved - so when you switch over to the CW Keyer, it will be set to the
last speed value detected with the decoder. I am not sure if this is a bug or a feature ;-)
This modus does not have many parameters (see the next section); maybe the most important is the ability
to switch the filter bandwidth of the audio decoder between narrow (ca 150 Hz) and wide (ca 600 Hz).
