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