Re: Bridging AllStarLink to other modes.

Hi Steve,

Couldn't agree more, in the UK our Ham licence actually says for educational purposes, and it's something us Amateurs have always done, including bending commercial systems to our needs be that a retuned ex Police radio to operate 2m or DMR networks.

In the UK on the hubNet, Peter G7RPG has used DVSwitch to link in DMR from BM into AllStar and it works well, and expands the reach to others, a worthwhile thing.

Subject: [DVSwitch] Bridging AllStarLink to other modes.
 I was forwarded a post from Doug WA3DSP concerning interconnection to
other services/modes on the HAMVOIP list. I have seen in the past that
Doug considers himself the guardian of all good audio and AllStarLink.
That is open to discussion. I think this needs to be addressed in the
community. Great audio quality is a hallmark of AllStarLink and no one
wants to compromise that. Another feature that singles out AllStarLink
is flexibility. People have done some amazing things with AllStarLink.
There are nodes and hubs that control what type of traffic pass through
the node or hub. There are quite a few nodes and hubs that welcome
experimentation. Connecting a foreign mode or service to a AllStarLink
node is never a good idea without prior discussion.

  One of the many features of AllStarLink that drew me in over 10 years
ago, was the ability to add features and devices. One very important
fact is that it is open source. Well, at least the official AllStarLink
distribution is. Channel drivers are available for EchoLink, D-Star, TLB
and USRP. If it's not there, it can be added. AllStarLink welcomes
people to add to and modify the open source available in github. If you
have an idea, bring it up, submit a pull request and let's see how it fits.

  People are going to extend the capabilities of AllStarLink, that is a
given. Those extensions may not be to everyone's liking. Under the
banner of DVSwitch, a few of us have been building tools for bridging
between different voice networks. One of those is AllStarLink. It does
not matter if the purpose of the bridge is to expose analog users to the
capabilities of a digital network or to display the capabilities of
AllStarLink to a group of digital voice users that are not aware of a
large network of open source analog nodes. There are quite a few hams
that do not know about AllStarLink. This gives them a taste. I'm pretty
sure every one of the digital voice radios in use support analog. Do we
really want to display a negative attitude to other communities? I can
tell you that not everyone on the digital voice networks want to see a
bridge to analog. They don't want "those noisy analog signals" on their
network. This is not a discussion of which voice mode is better. Nor is
it about how to make digital voice sound better. I tell people building
bridges the same thing, Don't just drop a analog bridge onto a digital
channel without discussion first. One digital network I have seen is
reporting over 10K calls per hour. (That might be a interesting stat to
collect for AllStarLink)

  Bridging networks is not the purpose of AllStarLink and I would rather
not see discussions of various networks on the AllStarLink user list.
There are other places for that. The open source nature of AllStarLink
lends itself to extension. Just be aware what you are doing and who it
will effect.
