SGARN Basics and Philosophy
« on: March 14, 2014, 09:54:46 PM »

The Second Generation Amateur Radio Network is an effort to start afresh, avoiding various pitfalls that the original AR network, the Packet network fell into.

SGARN has an e-group where discussion takes place, notifications originate, and operating schedules are occasionally posted:

The illustration below shows the landscape upon which the SGARN network must be built. Many of the mistakes made in designing the old network stemmed from an imperfect understanding of this information, so the image is worthy of some study if we are to avoid making those same mistakes again.

SGARN Structure, Policy

Perhaps the most persistent mistake made with the first network was that a stated desire for more content was seldom if ever answered by suggesting a move to a higher frequency band. Instead there was one bogus scheme after another to defy the laws of physics, as they apply to amateur radio, and worst of all were those who would offer the "assistance" of non-ham links.

SGARN has adopted the "go higher in frequency" response, the only one that offers a good result.

All other responses are obsolete, counterproductive.

Here are listed modules for the Second Generation Amateur Radio Net, listed by band designation: HF, VHF, UHF, SHF

Part of our task is to integrate these into a single, coherent network. Note that the content, the information distributed and exchanged on the different bands follows a definite hierarchy, related to the effective bandwidth available on each band.

SGARN Bandplan:

----------------------------- HF

Multicast bulletin network ( self organized )

Bulletins originating from organizations: ARRL, AMSAT etc.

----------------------------- VHF

Advanced Digital Network User Access ( BPQ32/FLDIGI KISS with advanced digital modes )

Multicast information distribution

HF content - plus Personal messaging, Bulletins originated by individual amateurs

----------------------------- UHF

Advanced Digital Network User Access ( BPQ32/FLDIGI KISS with advanced digital modes )

Advanced Digital Network Backbone Links ( BPQ32/FLDIGI KISS with advanced digital modes )

HF, VHF content - plus images, some binary files.

----------------------------- SHF

Advanced Digital Network Backbone Links ( BPQ32/FLDIGI KISS with advanced digital modes )

HF, VHF, UHF content - plus Amateur TCPIP - HSMM

================= Policy / Philosophy =================

No proprietary software or firmware.

No non-ham links or connections at any point.

As you go higher in frequency, start with what is distributed on lower frequencies - and build from there.

Avoid emulation, strive to innovate.

SGARN is all ham radio, and only ham radio. All transport and distribution of  data on the SGARN network shall be via amateur radio means (Pure RF) only. Stations that attempt to transport or link SGARN data over non-ham connections of any kind will be disavowed by SGARN, and their data will not be propagated over the network.

The internet can and should be a good source of information for SGARN, but should under no circumstance be utilized to transport SGARN network data, or to link one section of SGARN network to another.

As unpleasant as it is to shun a fellow amateur, it is much more unpleasant to allow them to undercut what we are doing, and damage the hobby's reputation through willful or thoughtless misbehavior. By setting and maintaining a standard of operation, we can assure SGARN's success and good reputation in the long term.
