Rejects bulls @WW over 5000 bytes from external BBSes to avoid saturating onward HF links within the network, please keep bulls a sensible length as you never know what links they may need to traverse!
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 QtSoundModem as a modem, you should select “QPSK V26A 2400bps” and a centre frequency of 1500 hz.
And 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.
