AUdelay "n"<br />
Default: 2 (20 msec.)<br />
Mode: Baudot, ASCII, FEC, FAX and Packet<br />
Host: AQ<br />
_________________________________ Parameters: _________________________________<br />
"n" - 0 - 120 specifies in units of 10 msec. intervals, the delay between<br />
PTT going active and the start of the transmit AFSK audio tones.<br />
_______________________________________________________________________________<br />
In some applications it may be desirable to create a delay from the time that<br />
the radio PTT line is keyed and the time that audio is produced from the <strong>PK</strong>-<strong>232</strong>.<br />
Most notably, on HF when an amplifier is used, arcing of the amplifier relay<br />
contacts may occur if drive to the amplifier is applied before the contacts have<br />
closed. If arcing occurs, increase AUDELAY slowly until the arcing stops.<br />
In VHF or UHF FM operation, some synthesized transceivers may produce<br />
undesirable spurious emissions, if audio and PTT are applied at the same time.<br />
These emissions may be reduced by setting AUDELAY to roughly 1/2 of TXDELAY.<br />
Please note that AUDELAY must always be less than TXDELAY. It is advisable that<br />
AUDELAY be set lower than TXDELAY by a setting of 10. For example, you have<br />
determined that a TXDELAY of 20 works well for your transceiver. Subtracting 10<br />
from 20 yields 10, which is the recommended setting for AUDELAY. If a setting<br />
of AUDELAY of 10 is too short, then set both TXDELAY and AUDELAY higher.<br />

AUTOBaud ON|OFF<br />
Default: OFF<br />
Mode: Command<br />
Host: Ab<br />
_________________________________ Parameters: _________________________________<br />
ON - Autobaud Routine always present at Power-ON or RESTART.<br />
OFF - Autobaud Routine active at Power-ON only if battery jumper is removed.<br />
_______________________________________________________________________________<br />
When AUTOBAUD is OFF (default), the unit performs the autobaud function only<br />
when powering ON or after a RESET. When AUTOBAUD is ON, the <strong>PK</strong>-<strong>232</strong> performs the<br />
autobaud routine EVERY time it is powered ON, and EVERY time the RESTART command<br />
is entered. The stored parameters (e.g. MYCALL) are saved if the battery jumper<br />
is connected. The unit displays the autobaud message at the same rate as the<br />
last setting of TBAUD. AUTOBAUD ON is helpful when moving the unit from one<br />
computer to another, where the terminal data rates are different.<br />
In the autobaud routine, only one asterisk (*) is needed to set the terminal<br />
speed TBAUD. The autobaud routine detects 110, 300, 600, 1200, 2400, 4800 and<br />
9600 baud, at either 7 bits even parity, or 8 bits no parity.<br />
