the command mode before each change) adjust the audio output level of the PTC-IIIusb
until the required output power is reached (e.g. <ESC> FSKA 100 <Return>). It should be
noted that the ALC level of the transceiver must not exceed the prescribed level (exactly
as with PSK). To prevent possible damage to the average TRX, caused by continuous
transmission, we recommend that the FSK output power should never exceed 50% of the
maximum PEP power. In the case of the average amateur transceiver of 100 watts, this
represents the 50 watt level. The internal impedance of the AF output stage of the PTC-
IIIusb is 330 Ohms and resistive.
6.43 HCr
Default setting: 0
Parameter: 0 Auto CHO after an empty line off.
1 Auto CHO after an empty line on.
If HCr is 1, then, in hostmode, a CHANGEOVER is carried out after an empty line
(double <CR> or <Return>).
6.44 Help
Remote
Help without parameters gives a list of all commands.
The PTC contains a short description of every command, so that the manual does not
need to be continually consulted. These descriptive messages can be obtained by using
Help, followed by the required command.
Help bau (or in shortened form h bau.)
From remote, Help results in only those commands that can be remote controlled being
listed.
A thorough description of each command can also be obtained by the remote station,
using Help <CMD>,
Help phase or Help bell.
6.45 LFignore
Default setting: 1
Parameter: 0 no insertion of <LF>.
1 insertion of <LF> after each <CR>.
2 multi-<CR>-supression
LFignore determines whether a <LF> is automatically appended to each <CR> that is
sent to the terminal. For LFignore 0 the characters are passed exactly as the PTC
receives them. For LFignore 1 <LF>'s sent to the PTC are ignored (refer also to
command ADdlf, chapter 6.2, page 45).
LFignore 2 activates in addition the multi-CR suppression with RTTY and
AMTOR/FEC reception. (Multiple <CR> in a row without other characters between are
suppressed except for the first <CR>. In the EOL (End Of Line) sequence in some US-
