the receiver until a Morse signal is heard. Starting with a low pitched tone, tune the receiver so
that the pitch slowly rises. When the receiver is tuned properly, the PHASE LOCK and DATA LEDs
should blink together in time with the CW tones. If the signal is very noisy, it will be necessary to
set the volume of the receiver to a lower level.
In both RTTY/ASCII and CW operation, some signals may not be copyable. This may be be-
cause of high levels of noise, coding of the message, transmission in a foreign language or other
reasons.
