Chapter 7 Maildrop Operation
Note : If you want a message to be deleted from your Maildrop after it’s been reverse-forwarded, leave
KILONFWD ON
; if you want to keep the message after its been forwarded, leave
KILONFWD OFF
.
With
KILONFWD OFF , after the message has been forwarded the message’s flag will change from “F” to “Y” to
show that it has been read and sent.
Mode Specific Commands
Not all the modes share the same command structure and appearance when using the Maildrop. You’ve read about
how to operate your Maildrop using packet. What follows is how to use the Maildrop in the other two Maildrop
modes, AMTOR and PACTOR.
AMTOR MailDrop
The AMTOR Maildrop user interface is slightly different from the packet interface due to the differences between
the two modes.
With
CODE 0 and the ITA#2 alphabet used in AMTOR, only upper-case characters are sent. If you set CODE to 2
(enabling the Cyrillic extensions), both uppercase and lowercase characters can be sent and received. See
CODE
for information and limitations of this feature.
When a station links with your AMTOR Maildrop, your Maildrop first identifies you by sending your callsign and
the amount of free Maildrop memory as shown in the example below:
DE WF7A ( AEA DSP232 ) 17528 FREE.
The Maildrop then sends the user the
MTEXT string if MMSG is ON . The default text is shown below:
WELCOME TO MY AEA DSP232 MAILDROP.
TYPE H FOR HELP.
Since AMTOR transmissions don’t self-identify (like in packet), your Maildrop will force the user to identify in one
of three possible ways: automatically, by request, and user input.
Automatic:
Your Maildrop will send “STAND BY”, then the WRU request to the user. Be sure you’ve entered
an AAB message consisting of “QRA (
MYCALL
) (
MYSELCALL
) (
MYIDENT
).
Request:
AMTOR users who haven’t entered an AAB response can’t 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
“(
MYCALL ) +?” to the calling station. The calling station then has three minutes to respond with its
callsign. The ID must contain either “QRA” or “DE” and must end with “+?”. So, if KG6ZL was
calling he’d send the following:
QRA KG6ZL +?
If no satisfactory ID occurs within three minutes from the establishment of the link, the link will be
automatically terminated.
User Input
Experienced AMTOR users may want to save time by simply sending QRA followed by their
callsign immediately after establishing the link. For example, KB6IUX may simply enter the
following entry immediately after establishing an ARQ link with you:
QRA ?
User Prompts
The command prompt that the Maildrop sends the user in AMTOR is slightly different from the one used in the
packet mode:
WF7A DE KB6IUX GA+?
