SCS PTC-IIex, Manual

Page: 63 / 220

6 Commands
Switch CW identification to Audio-Only:
cmd:
CW 1 2
<Return>
For CW identification, one's own callsign (
MYCALL
) is always used.
The CWID amplitude is generally 3 dB lower than the FSKA level!
6.28 CWMoni
Default setting: 1
Parameter: 0 CW monitor tone disabled.
1 CW monitor tone enabled (TX).
2 CW monitor tone enabled (RX /TX).
Defindes the operation of the CW monitor:
With
CWMoni
1, the PTC produces a side tone using the internal buzzer representing the
transmitted CW characters entered at the CW terminal.
CWMoni
2 also produces a tone from the received demodulated CW characters from the
CW terminal.
6.29 CWSpeed
Default setting: 160
Parameter: X 40... 1200, CW speed in LpM.
The
CWSpeed
command enables the CW speed to be set continuously between 40 and
1200 LpM (Letters per minute).
The CW speed applies to the CW ID as well as to the CW terminal.
6.30 CWTerm
Default setting: no
Parameter: X 40... 400, Start receiving speed in LpM.
The CWTerm command activates the CW terminal of the PTC-IIex. The actual speed
depends on the
CWSpeed
parameter. The keying takes place using the PTT line, as with
the
CWID
. The FSK line remains constant on the Mark frequency. The AFSK signal
amplitude is also keyed. The frequency for AFSK is defined by the
Center
command in
the
AUdio
menu (refer to chapter 7.2 , page 91 ).
After activating the CW terminal, characters from the keyboard, that can be translated
into Morse, are transmitted as Morse code by the PTC.
If an argument is entered, the decoder starts in the fix-speed-mode, that means that
automatic speed adaption is disabled. This is recommended for recording
commercial CW
transmissions (weather report etc.), whose speeds are known.
