We are seeking to establish a standard for a digital network style system to handle emergency communications. We have established certain standards we are looking to follow. The mode/protocol/package etc. should be based on weak signal HF capability. The mode/protocol/package should be able to handle transferring of data in more than just ascii text format (ie: transfer files such as spreadsheets, etc.) The system must NOT require proprietary hardware such as pactor II/III modems. In other words, standard modems and/or sound card based. Before the flames start, there are already some out there that are being tested that actually meet these requirements, but are still in testing stages. Any suggestions would be greatly appreciated John KE5HAM

John, Who's 'we' in this context? Why not join one of the existing teams - NBEMS is working well.

John, You might consider NBEMS for HF: www.w1hkj.com/NBEMS. We have optimized the DominoEx and MFSK16 modes for high static conditions and also have a verification program called Wrap if you do not want to use flarq. 73 Skip KH6TY NBEMS Development Team John Taylor wrote: We are seeking to establish a standard for a digital network style system to handle emergency communications.

Hi John Why not try ALE400 ARQ mode in Patrick's Multipsk?. It has all qualification you are looking for. 73 de LA5VNA Steinar John Taylor wrote: We are seeking to establish a standard for a digital network style system to handle emergency communications.

Hello John, For transmissions without error, there is a mode which name is ARQ FAE, available at 125 or 50 bauds (ALE400). You can transmit small files, messages, mails, APRS positions at a reasonable speed. There are a lot of possibilities. This mode derives from ALE (DBM) and PAX but it is only available in Multipsk (however the specifications are public). Look at a.. ALE and ALE400 easy with Multipsk(http://f6cte.free.fr/ALE_and_ALE400_easy_with_Multipsk.doc) a.. The ARQ FAE beacon easy with Multipsk (http://f6cte.free.fr/The_ARQ_FAE_beacon_easy_with_Multipsk.doc) You must consider also ALE (141A) which has a lot of possibilities, is available in many pieces of softwares and hardware and has a very good support. Call ID and Prop ID could also be of interest (but I don't know your needs). The_Call_ID_and_Prop_ID_easy_with_Multipsk.doc (MS Word Doc, 425 KB) 73 Patrick
