Your comments about "Grandma's birthday" indicates that you understand very little concerning traffic handling which has been a part of amateur radio from the very begining and is where the "Relay" in "American Radio Relay League" comes from.. The pupose of the yes maybe boring everyday messages is to keep a cadre of trained message handlers for those times when ham radio is called upon to provide communications during disasters and other emergenices when other modes of communication are down or otherwise unavailable, including the World Wide Web. The National Traffic System exists and has operated for many decades in this fashion. A natural extension of this is NTS Digital which indeed does operate automatic message handling systems primarily using Pactor and operates concurrently with the traditional manual NTS at all levels. However NTS Digital for the most part still uses what has become to be called Winlink Classic where almost all of the forwarding is done via RF. Yes we do scan, but Winlink Classic also has a busy frequency detector built into its scanner function. While not perfect it does result in inhibiting many connections when the frequency is busy. Personally I have seen it work upon detecting CW, RTTY, Pactor 1, PSK31 and some other digital modes and even just plain carrier. NTS Digital operates almost exclusively in the very small existing automatical control subbands. Indeed during RTTY contests when many of the activity moves into these autocontrol subbands our traffic handling ability is severely affected due to the busy detectors in the software. How big is this operation?... For March 2010 the NTS Digital system in Eastern Area which comprises most of the East Coast and the 1, 2, 3, 4, and 8 callsign areas and Eastern Canada handled over 6000 messages via the digital systems. Similar traffic levels are also posted by the other two areas, Central and Pacific covering the rest of the US and Canada Dave WB2FTX Easten Area Digital Coordinator- NTS Digital ARRL --- In [email protected], Andy obrien <k3uka...@...> wrote: A quick fix for this entire mess is to suggest to those running automated traffic stations to use the World Wide Web. The web is faster, less likely to be affected by atmospheric changes, and remove a thorn in the side of many ham radio operators. I have only intercepted messages being relayed by an automated traffic handling station a few times. The traffic was dull and trivial. It was hardly worth the mayhem now being caused by their operation. Some may disagree with me on the point of traffic being trivial. I just cannot find "happy birthday grandma" to be very important. Grandma would get her birthday which is much quicker through the Web.
