Chapter 9 AMTOR Operation
When
DAYTIME
has been set, entries in the Heard log are time stamped. With
DAYSTAMP ON
the date is also
shown. An example of the MHEARD display is shown below:
DAYSTAMP ON DAYSTAMP OFF
05-Nov-95 21:42:27 KG6ZL 21:42:27 KG6ZL
05-Nov-95 21:42:24 KB6IUX* 21:42:24 KB6IUX*
Previously, stations heard directly were displayed with an asterisk (“W1AW*”) and digipeated stations were shown
without (“W2SZ”). Digipeating isn’t used as much as it used to be—most stations now use nodes so we’ve stopped
using the asterisk. However, for those few cases in which a station is heard indirectly through a digipeater, that
station’s callsign is displayed with the message, “
via digi
”.
In addition, I- and U-frame packets with PIDs of CF and CD are shown with the indicators “N/R” (for Net/ROM)
and “IP” respectively. AMTOR and PACTOR stations accessing the Maildrop or the gateway are shown in the
MHEARD list with an “AMTOR” or “PACTOR” indicator.
Clear the
MHEARD list with a % , & , N , N O , NONE or OFF as arguments.
MId
n Default: 0 (00 sec.)
Mode: packet, AMTOR, PACTOR Host: Mi
“
n ” 0 - 250 specifies the Morse ID timing in units of 10-second increments.
0 Zero disables this function.
If “
n ” is set to a value between 1 and 250, the DSP will periodically issue a 20 wpm Morse ID. For example, a MID
of
177
would cause a Morse ID to be sent every 1,770 seconds (29.5 minutes). A Morse ID will be transmitted only
if a packet was sent since the last Morse ID. The Morse ID uses TXDELAY , PPERSIST and DCD .
If
MID is set to a value other than 0 , ID will force a Morse ID immediately. If both HID and MID are active, the
Morse ID will be sent first.
MID normally sends a Morse ID using on/off keying of the low tone. If FSK keying of both tones is desired to
prevent stations from transmitting over your Morse ID, see the
UBIT 12
command.
Morse ID now works in AMTOR and PACTOR modes on both ARQ and broadcast transmissions. Because of the
nature of these operating modes, the destination station will go into an error state when your TNC sends a Morse
ID, but should recover data synchronization immediately afterwards.
MMsg ON | OFF Default: OFF
Mode: packet, AMTOR and PACTOR Maildrop Host: MU
OFF
The
MTEXT
message isn’t sent at all.
ON The stored MTEXT message is sent as the first response after an AMTOR or PACTOR link or packet
connect to the Maildrop is established.
MMSG
enables or disables automatic transmission of the
MTEXT
message when your AMTOR, PACTOR or
packet Maildrop links with another station.
