PK-232 MBX – OPERATING MANUAL PACKET-RADIO
4/91 4-7 42
Remember that in the first example we saw the two stations Connect. Now that they are
connected, they may exchange data packets.
The following packet is a Beacon packet from KD7NM. Since we see the packet is ad-
dressed to "MAIL" we know KD7NM is probably a Packet Bulletin Board System (PBBS).
KD7NM*>MAIL:
Mail for: K6RFK N7ML
The data section of this packet says "Mail for: K6RFK N7ML". This Beacon lets people
know that K6RFK and N7ML have mail waiting on the KD7NM PBBS without having to con-
nect.
The following Beacon packet is intended as identification for a NET/ROM level-3 Packet
networking switch.
N7HWD-8*>ID:
NET/ROM 1.3 (SEA)
In this case, the Packet Switch is using the callsign N7HWD-8, but also uses the alias SEA
as a callsign. There are many types of Packet Switches now in use, but NET/ROM is one
of the most popular. We will briefly discuss using a NET/ROM switch later in this chapter
since most switches operate in much the same way.
The packet below was sent by the network switch SEA to N7ML.
SEA*>N7ML:
SEA:N7HWD-8> Connected to #SEA:N7HWD-7
The packet above from SEA contains the data "SEA:N7HWD-8> Connected to
#SEA:N7HWD-7". This message tells N7ML that he is now connected to another port on
the SEA Node named #SEA. Again, we will talk more about how and why N7ML might
want to do this later in the chapter.
The following packet is again from K6RFK to N7GMF and is being digipeated through
N7ALW. This packet indicates that K6RFK is finished talking to N7GMF and wants to Dis-
connect. Again we see that we are not hearing K6RFK, rather we are hearing N7ALW as
indicated by the asterisk (*) after his call.
K6RFK>N7ALW*>N7GMF [D]
The following packet is an acknowledgment (or simply called an ACK) that lets K6RFK
know that N7GMF has acknowledged the Disconnect request sent above. K6RFK and
N7GMF are no longer Connected.
N7GMF>N7ALW*>K6RFK (UA)
4.3.3 What Happens When You Connect
If you are working with a friend who is familiar with Packet, you may want to skip to sec-
tion 4.4. If you are on your own, the following three sections will help you learn what to
expect on VHF/UHF packet.
