Hi Peter et all, I have some experience in DMR & multimode servers
using udp for voice packets in the 'one shot hope for the best result'
connectionless nature of UDP traffic needed to
handle the immense traffic load and also multiple streams together, such
as the DMR openbridge system,
However with this type of text report data I thought tcp may be viable
as Phillip describes, with capable infrastructure to handle it.
Perhaps multiple servers to handle areas based on call ?
I am happy to host one for VK.

Hi Adrian, messages via TCP put a requirement on the local PC to
handle errors which all add complexity and resources to do it. The
messages have to be sent, an answer waited for and if no answer, sent
again until a time out is received, then handle this time out... UDP
on the other hand is a send it and move on to the next thing process
which requires very little overhead and no error handling by the
sender. This is why UDP messaging is so popular as you do not have
to worry about the outcome of a send and generally works on most
networks.
Regards,
Peter, vk5pj
