[digitalradio] Re: Network 105 / Multipsk/ New idea
As many people know, I've been trying varying ideas of a way to post information on-line about who is QRV. Sked pages, HRGnet, Hamspots, etc, etc. In thinking about Network 105, I remembered the old MHEARD packet command and how easy and convenient that was. The fact that 300 baud packet is not as robust as modes like Olivia may actually serve a useful purpose. If you hear a signal on 300 baud packet, chances are you can work it with other modes. If you really want to talk to a particular station and the path is marginal, you could use the network part of Network 105 and go in via a node . 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. Of course , this is just one band, but if the idea takes off...maybe there would be a 30 or 40 frequency for times 20M is dead. With 10M radio selling for $25.00 at hamfests nowadays, I am also intrigued about a 10M network of low powered (25 watts) packet stations that could be quickly utilized. This would allow dedicated full-time packet stations and free up the main rig for other operations. Multipsk installs easily on older computers, so that old laptop of PC laying around your basement could also be part of a dedicated station, or that old TNC you have not used in years (I have two!) Just a few random thoughts from me, but Sholto and Tony's experiments have established that this mode and network while old school could actually be a viable tool in this digital mode age.

Net 105 is a remarkable network and one can only imagine how many messages have been processed since the 1980s'; all on a shared channel with a relatively narrow mode. I've used the network to connect to Sholto when there is no propagation between us. I can log into his packet mailbox and leave him a message thanks to magic of digipeating. Your program does a wonderful job on HF packet.

ARRL Burt Amero VE1AMA (SK) 05/29/2010 Bernard Joseph âBurtâ Amero, VE1AMA of Auburn, Nova Scotia, Canada, passed away Tuesday, May 25, after a long battle with cancer. He was 67. Burt was known worldwide as the founder of âNetwork 105â. Established in 1986, Network 105 is a global packet radio network that is active today on 14.105 MHz. Burt was also quite active in various public service functions through the years. Online condolences can be made through the Middleton Funeral home Web site. -- Our thanks to Tony Bombardiere, K2MO, for providing the information for this story.

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 k3uka...@... wrote: As many people know, I've been trying varying ideas of a way to post information on-line about who is QRV.
