CW-Identification
The CWID of the PSK31 terminal always is activated in the
Audio Only
mode, i.e. the
PTT is active during the whole time and only the tone signal is keyed according to the
rhythm of the CW characters. The special pulse wave shape of the CW character
generates a relatively narrow spectrum, so that the adjacent PSK31 channels are not
disturbed during the CWID. The PTC-IIIusb sends an additional CWID after a PSK31
transmission if the CWID-Parameter (refer to
CWid
0. If the parameter is higher than 1, also before each PSK31 transmission a CW
identification is sent.
