Prob...Yes it should be much more robust than PSK31. Probably not better than Olivia but it is much narrower (200Hz) for the same speed. Not as good as JT65A but it is a keyboard QSO mode you are not limited to sending fixed format information (or 13 characters) and it is faster and decodes in real time, no clock syncing necessary. You could say that it aims to achieve what ROS mode does, but without the excessive use of bandwidth.<br /><br />The TNC is essentially the sound card modem. You get two programs, one a fairly primitive chat application and the TNC with waterfall display and status indicators. The two talk to each other using TCP/IP. It would be possible for HRD, Fldigi and other programs to talk to the TNC in the same way so people could use their own familiar interface. That's what I hope to do with KComm if the mode proves popular enough to be worth persevering with.<br /><br />At the moment we are only using the FEC (Forward Error Correction) mode. But there will also be an ARQ (Automatic Repeat reQuest) mode which will ask for repeats of blocks that were not received correctly so it will keep on going until you get perfect copy just like Pactor does. So I think V4 really has the potential to exceed what is possible with other sound card modes. But it is early days and the value of getting involved now is to help with testing and getting the bugs out of the software.Anonymoushttps://www.blogger.com/profile/11984840704237681015noreply@blogger.comtag:blogger.com,1999:blog-953397841255562532.post-66924547839583795832010-12-09T08:01:48.042+00:002010-12-09T08:01:48.042+00:00Hi Julian, it looks promising.

What you show us till now is also possible with PSK31 or Olivia or any other mode. Anyway, I'll await more postings on your blog. What I understand is that V4 is better as PSK31 but less sensitive as JT65A. Now JT65A does need time to decode a message and V4 probabely decodes realtime, true? <br />73, BasPE4BAS, Bashttps://www.blogger.com/profile/12958141238330445285noreply@blogger.comtag:blogger.com,1999:blog-953397841255562532.post-64038487947068859112010-12-08T23:10:02.872+00:002010-12-08T23:10:02.872+00:00V4 could become the most practical and popular dig...V4 could become the most practical and popular digital mode since PSK31 due to its robustness and reasonable bandwidth along with speedy chat interactions.<br /><br />Keep us posted, Julian.<br /><br />Steve KB3SIISteve Silvermanhttps://www.blogger.com/profile/12286830078028283225noreply@blogger.comtag:blogger.com,1999:blog-953397841255562532.post-21639803463723113202010-12-08T16:50:58.845+00:002010-12-08T16:50:58.845+00:00No. The WINMOR protocol is intended for data trans...No. The WINMOR protocol is intended for data transmissions like WinMail and APRS. This is an offspring of that, designed specifically as a keyboard chat mode. By the look of things you may find it between the top of PSK31 activity and the start of JT65A, though it is not 'channelized' and can be used anywhere a 200Hz wide digital mode can legally be used.Anonymoushttps://www.blogger.com/profile/11984840704237681015noreply@blogger.comtag:blogger.com,1999:blog-953397841255562532.post-62788310514498766342010-12-08T16:40:19.386+00:002010-12-08T16:40:19.386+00:00Sound indeed interesting Julian.

Or something like PSKMail. Hope to read from it soon. 73, BasPE4BAS, Bashttps://www.blogger.com/profile/12958141238330445285noreply@blogger.comtag:blogger.com,1999:blog-953397841255562532.post-82613281424906642482010-12-08T16:35:38.560+00:002010-12-08T16:35:38.560+00:00Hello Julian, sounds interesting.
