WhatsPac
WhatsPac is a great new application for packet that has chat channels and private messages. Visit http://whatspac.oarc.uk/ for more information. Note that the project is in alpha so a few things are still being ironed out.
It is possible to route to the main WhatsPac server node MB7NPW from GB7BSK (if direct L4 connection fails, try L2 via GB7WIN → GB7BDH → MB7NPW-9). Have a look a the packet map to get an idea of routes and feel free to drop a message by packet mail or on the OARC discord #whatspac if you need help.
LoRa APRS (Port 4)
The packet node is connected to the MB7UBA LoRa APRS digi/iGate, allowing you to monitor local LoRa APRS traffic from the node. To do this run the command lis 4 and traffic will be displayed live. To end, give the command lis.
Note that while in listen mode (lis) you can in theory send an AX.25 CQ, but this is not really an APRS packet, and so you should avoid this as it will just use up the shared APRS frequency.
Advanced users may send APRS using the unproto command, but this requires a good knowledge of the APRS protocol as you will essentially construct the APRS packet yourself, so only try this if you know what you are doing!
QtSoundModem Settings
If using QtSoundModem as a modem, in the modem settings (Settings → Setup Modems) enable FX25 and IL2P for RX+TX, and tick the CRC box.
AX.25 2.2 with SREJ
It is also possible to connect using AX.25 2.2, which may have some advantages described below.
To do this from a BPQ node, use the “nc” (new connect) command, rather than the more common “c” (or “connect”) command, and force L2 (no NET/ROM) by putting an exclamation mark in front of the callsign. E.g.:
nc 2 !gb7bsk
(The 2 in this example specifies the port, use the “ports” command on a node to work out which one is on the appropriate band).
One advantage of this type of connection is the ability for SREJ, or selective reject, to be used. Normally, several packet may be sent out in order, and if one of them is not received correctly the entire batch is rejected with a REJ message. The whole set of packets then has to be retransmitted. SREJ allows only specific packets to be rejected, so only those individual packet need to be retransmitted.
As of BPQ version 6.0.24.69, netrom L4 connections will use AX.25 2.2 for the underlying L2 connection, with all the SREJ benefits without you having to do anything else.
