+===== WhatsPac =====
+WhatsPac is a great new application for packet that has chat channels and private messages. Visit http://whatspac.m0ahn.co.uk:88/ for more information. Note that the project is in alpha so a few things are still being ironed out.
+{{:nodes:whatspac.png?400|}}
+It is possible to route to the main WhatsPac server node [[nodes:mb7npw|MB7NPW]] from GB7BSK, although the most stable route includes one AXIP link, the rest is all RF. Have a look a the **[[https://nodes.ukpacketradio.network/packet-network-map.html?rfonly=1|packet map]]** to get an idea of routes and feel free to drop 2E0HKD a message by packet mail or on the OARC discord if you need help with routing.
 ===== QtSoundModem Settings =====
-**NOTE: The new NinoTNC 3600 bps mode does not yet work with QtSoundModem, but compatibility is being worked on! Unfortunately the 2400 bps mode mentioned below will no longer work with the node.**
+If using [[https://www.cantab.net/users/john.wiseman/Documents/QtSoundModem.html|QtSoundModem]] as a modem, you should select "QPSK AX.25 3600bd" and a centre frequency of 1650 hz.

+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.:
@@ Line 51: / Line 58: @@
 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.
-===== LoRA-APRS =====
+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.
-APRS over LoRA is also run under GB7BSK-10. Initially this is a separate system, but there are plans to create some interaction with the packet node so you can interact with one from the other (within some limits, no large transfers over LoRa which would swamp the frequency!)
-This runs on 439.9125 MHz, Bandwidth 125khz, Spreading Factor 12, Coding Rate 4/5 (ie. enter "5" for the coding rate). This is the same frequency for LoRa based APRS across the UK. As a shared frequency, try not to dominate it too much just like standard APRS.
-For those that don't know, APRS over LoRA is exactly what it sounds like: [[https://en.wikipedia.org/wiki/Automatic_Packet_Reporting_System|Automatic Packet Reporting System (APRS)]] packets sent using using [[https://en.wikipedia.org/wiki/LoRa|LoRa]] radio modulation, instead of the more common FM modulation used in standard APRS.
-In fact APRS packets are in the AX.25 format, just like regular packet radio, but it uses the format in a different way and so is not directly compatible at the protocol level with traditional packet radio. It is possible to run a packet node and/or BBS over the LoRa modulation as well, and GB7BSK may experiment with this at some point as well.
-A LoRa-only APRS map can be found at [[https://lora.ham-radio-op.net/]], though packets from LoRa based devices are still found on common APRS sites like [[https://aprs.fi/|aprs.fi]].
