Chapter 5 Packet Operation
3) Set MONITOR to at least 1 .
4) Go to Converse mode by entering K , then send a few packets by pressing the ( RETURN ) key. You should
see the outgoing packets on your own screen echoed back as they’re digipeated by the other station.
5) Start reducing
TXDELAY
by units of
5
each time, making sure the other station is still digipeating all of
your
UNPROTO
packets.
Eventually you’ll find a value where the other station can no longer copy your packets accurately enough to digipeat
them.When this happens, increase
TXDELAY
in units of one or two until the other station again digipeats all of
your packets again. This will be the optimum setting of TXDELAY for that particular radio .
After
TXDELAY
has been adjusted, you may want to adjust the audio delay (
AUDELAY
), too, using the same
procedure as above. (See
AUDELAY
for more information.)
Packeting Through Voice Repeaters
Although it isn’t common, packet can be used through voice repeaters. When sending packets through a repeater
you may require a longer key-up delay than is normally needed for direct communications.
AXDELAY adds more
key-up delay in your DSP so that the repeater can key-up at the proper time. AXHANG sets the timespan needed for
the repeater to “drop.”
Although it’s seldom needed, the DSP does have an input for squelch information from a transceiver through the
RADIO connectors. This input should be used with the
SQUELCH command.
Packet Formatting and Editing
Some of your DSP’s command parameters affect how your packets are formatted—how your typing appears to the
rest of the world. Other commands let you correct typing errors before your packet is sent, cancel lines, or entire
packets.
(
RETURN ) s and Linefeeds
Most hams use packet radio for sending and receiving messages or just for conversation. The character used to send
a packet is defined with the command
SENDPAC
which defaults to a (
RETURN
) ($0D). You can change the
SENDPAC
character, but you’ll find the (
RETURN
) or (
ENTER
) key to be a natural choice.
Similarly, your DSP will include a (
RETURN ) in the packet you send to the other station since this makes for a
more natural conversation. ACRPACK controls this feature, and most people will never want to change this.
The DSP also has the capability of adding a linefeed character ($0A) automatically to packets that you send to
others. If you encounter a station or two says your packets are overprinting, you may want to turn the
ALFPACK or
ILFPACK ON for them.
Canceling Lines and Packets
Most of the time, the Backspace key—or the Delete key on some machines—is all that’s needed to edit a line before
it’s sent. Occasionally, it may be helpful to cancel a typed line or the entire packet you’re entering with one
keystroke. The
CANLINE
character, (
CTRL-X
) , will cancel the entire line you’re typing; the
CANPAC
character,
(
CTRL-Y
), will delete the entire packet.
Redisplaying Text
If you’ve erased and retyped lots of characters, you may want to see a “fresh” screen (especially if BKONDEL is
OFF .) The REDISPLAY character ( CTRL-R ) will refresh your screen and will display any packets you might
have received while you were typing.
The PASS Character
Sometimes you may want to include a special input character such as a ( RETURN ) in a packet without forcing an
action to happen. For example, to send several blank lines in the same packet, you must include a ( RETURN ) at the
