Don't know where Dave Little is getting his info, but I can tell you that NTS Digital is very active on Pactor I, Pactor II and some Pactor III... I will mainly comment on Eastern Area NTS Digital which I am directly responsible for, but similar activty exists in both Central and Pacific Areas NTS Digital.... For Eastern Area we typically handle 10,000 to 12,000 messages a month We have 6 24/7 MBO stations, the rest are Digital Relay stations removing and sending NTS via these MBOs... Also liaisions and connections with the Central and Pacific Area MBO hubs. Questions wb2...@optonline.net
73 Dave WB2FTX Eastern Area Digital Coordinator- NTS Digital ----- Original Message ----- From: Rick W To: digitalradio@yahoogroups.com Sent: Thursday, March 05, 2009 10:32 PM Subject: Re: [digitalradio] NTS Digital Hi Dave, I have heard of the use of MT-63 for many years on MARS circuits, but don't think I had heard about the digital SSTV program being used. It makes tremendous sense since they are often involved in sending bulletins to their members. With one to many it is possible to have 100% ARQ with EasyPal although it is after the fact ARQ. A bit cumbersome, but practical for insuring a group receives exactly correct data. Unfortunately U.S. hams can not use mixed phone and text digital in the HF bands unless they are sending fax/image. Since most of the NTS traffic is short text messages, we can not do that in the phone areas, so we have to confine it to the RTTY/data portions. 73, Rick, KV9U David Little wrote: > Rick, > > Army MARS is using MT-63 on mixed mode nets with some regularity. > > We also use Olivia when conditions warrant the slower speed of > transmission. > > Easypal is also being used for picture transmission, as well as text > broadcasts. > > David > KD4NUE > > ------------------------------------------------------------------------------ No virus found in this incoming message.
