Andy & all,

Well of course that's the beauty of packet, it's a time and frequency sharing 
mode so there's no problem with an ongoing QSO or many QSOs at once, you are 
not going to significantly affect channel availability if your FRACK setting is 
appropriate to the Network. A value of 6 is about right for HF. These days 
there are no full server bbs to bbs mail transfers so it's a much more friendly 
experience and there are many QSOs ongoing on Network 105.

MultiPSK and MixW both do HF packet very well but there is an alternative which 
is much easier to "interface" to other services.

AGWPE is a freeware packet engine and provides a tcp/ip bridge.

For instance, you can configure AGWPE to run 300 baud AFSK packet on one 
channel of your sound card and 1200bps AFSK on the other channel. 

You could run HF packet simultaneously with VHF packet. Using John's excellent 
BPQ32 software you can run a full node with multiple ports. 

Have 2 sound cards in your PC? Another 2 channels... one could be ARPS if you 
wanted.

Have a friend running AGWPE? Link your station to his via tcp/ip...

How about a WL2K RMS on your VHF side? I run such an RMS which is available 
thru my HF or VHF port and provides an excellent local WL2K gateway.

The WL2K RMS will also directly interface to AGWPE so there is not even a need 
to run a node if you don't wish to.

The power in packet, whether it's HF or VHF is the "Network" it's connected to.

For those wanting to learn more we have a Network 105 yahoo group and we'd be 
delighted to help you get started. We're also looking for more node stations, 
particularly in the West, central Canada and DX but all are welcome.
