7.6 AMTOR MailDrop Operation<br />
The <strong>PK</strong>-<strong>232</strong> now allows AMTOR access to the Packet MailDrop described in<br />
Chapter 5 of this manual. Messages that originate in Packet can now<br />
be accessed remotely in AMTOR and messages that originate from a<br />
remote AMTOR station can be accessed by Packet users of your MailDrop.<br />
Make sure that you understand MailDrop Operation in Chapter 5 and the<br />
basic AMTOR operation described earlier in this chapter before putting<br />
your AMTOR MailDrop on the air.<br />
7.6.1 Special <strong>Operating</strong> Considerations<br />
The AMTOR MailDrop has been designed with a "Watchdog" safety feature<br />
so that it may perform safely without constant attention. If a remote<br />
station is linked with your AMTOR MailDrop and no traffic is passed<br />
for 5 minutes, the link will drop and your transmitter shut off.<br />
At this time however, unattended operation below 30 MHz is not legal<br />
for US amateurs unless they hold a Special Temporary Authorization<br />
(STA) from the FCC for this purpose. This restriction may someday<br />
change, but until then US amateurs must be sure to always have control<br />
of their HF transmitters when any automatic device such as the <strong>PK</strong>-<strong>232</strong><br />
MailDrop is in operation.<br />
With this in mind, we have designed the AMTOR MailDrop so that it can<br />
be enabled or disabled at any time during an ARQ link simply by<br />
turning the command TMAIL (TOR MAIL) ON and OFF. This allows you the<br />
SYSOP to make your MailDrop available to any station you are linked<br />
with at a moment's notice. This could come in handy should you want<br />
to forward a message from an AMTOR station into the Packet network.<br />
See toe CODE 2 command for upper and lower case text in AMTOR.<br />
7.6.2 Settings For AMTOR MailDrop Operation<br />
Before a remote AMTOR user can access your MailDrop, be certain that<br />
MYCALL is set to your Amateur callsign and MYSELCAL is set to your<br />
4-character AMTOR SelCall. To allow CCIR 625 AMTOR access to your<br />
MailDrop, then your 7-character MYIDENT must be entered as well. Once<br />
these commands have been entered, you must then enter the AMTOR mode.<br />
7.6.3 Starting AMTOR MailDrop Operation<br />
Remote access to your AMTOR MailDrop is controlled by the command<br />
TMAIL which is short for TOR MAIL. The TMAIL command controls remote<br />
access to the AMTOR MailDrop in the same way that the MAILDROP command<br />
controls remote Packet access.<br />
Turn the TMAIL command ON (default OFF) to allow remote stations to<br />
access your MailDrop in ARQ AMTOR. Turn TMAIL OFF to have normal ARQ<br />
QSOs with other stations in the AMTOR mode.<br />
7.6.4 Local Logon to the MailDrop<br />
To locally access your MailDrop use the MDCHECK command as described<br />
in chapter 5 of the manual on MailDrop operation.<br />
