Re: [digitalradio] Re: Network 105 / Multipsk/ New idea
The idea is not new. Pskmail has all this capability built in natively. Rein PA0R Andy all, If you establish a connection keyboard to keyboard , and do not wish to tie up the frequency, then you could QSY and pick a different mode 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. http://groups.yahoo.com/group/network105/ 73 Sholto --- In digitalradio@yahoogroups.com, obrienaj wrote: As many people know, I've been trying varying ideas of a way to post information on-line about who is QRV.

Tony, It would be interesting to experiment with packet over nvis paths too. The higher signal to noise ratio typical with nvis would really speed throughput. Maybe you could devise a simulation of this Tony? Another idea which keeps nagging at me is using SCS's Robust Packet with their fairly cheap kiss Tracker TNC. Robust packet looks like it either works at 200 or 600 baud with a fairly narrow bandwidth. I can imagine, should the 300 baud limit be abolished (FCC please!) then an nvis network of 600 baud Robust Packet (either SCS or a sound card version) coupled with the flexibility and features of John's BPQ node software might prove an excellent emcom facility. Even plain old FSK HF packet is dramatically enhanced by the parallel decoders working in the SCS Tracker. 73 Sholto --- In digitalradio@yahoogroups.com, Tony d...@... wrote: Patrick, Sholto is the one who twisted my arm to revisit HF Packet.
