PK-232 MBX Operating Manual - N3UJJ

7.6.4.1 Remote Logon to your AMTOR MailDrop
The AMTOR maildrop user interface is slightly different from the
packet interface due to the differences between the two modes.
When CODE is set to 0 and the ITA#2 alphabet is used in AMTOR, only
UPPER case characters are sent. If you the SYSOP set CODE to 2
enabling the Cyrillic extensions, both upper and lower case characters
can be sent and received. See the CODE command for information and
limitations of this feature.
When a station links with your AMTOR MailDrop, your PK-232 first
identifies your station by sending your callsign and the amount of
free MailDrop memory as shown below:
DE WX7AAA (AEA PK-232M) 17528 FREE.
The PK-232 then sends the user the MTEXT string if the MailDrop
message command (MMSG) is ON. The default text is shown below:
WELCOME TO MY AEA PK-232M MAILDROP.
TYPE H FOR HELP.
Since AMTOR transmissions do not self-identify, your MailDrop will
force the remote user to identify in one of three possible ways.
The first way is automatic:
Your MailDrop will send "STAND BY" and then the WRU request to the
remote user. Always be sure you have entered a proper Auto-Answerback
(AAB) message consisting of "QRA YOURCALL YOUR_MYSELCAL YOUR_MYIDENT"
as described earlier in this chapter.
The second way covers beginning AMTOR users:
AMTOR users who have not entered a proper Auto-AnswerBack response or
for some reason have the WRU feature disabled cannot be automatically
identified by your MailDrop. In this case, your MailDrop will ask the
calling station to identify as follows:
After 10 seconds your MailDrop will ask the calling station to
identify by sending "QRZ? DE "your callsign+?" to the calling station.
The calling station then has 3 minutes to respond with its callsign.
The ID must contain either "QRA" or "DE" and must end with "+?".
An Amateur with the call WX7BBB would send the following:
QRA WX7BBB +?
If no satisfactory ID occurs within 3 minutes from the establishment
of the link, the link is automatically shut down.
The third way covers experienced users:
Experienced AMTOR users may want to save time by simply sending QRA
followed by their callsign immediately after establishing the link.
For example station WX7BBB may simply enter the following immediately
after establishing the ARQ link.
QRA WX7BBB +?
