I'm not opposed to linking different protocols, but there is value in some of the objections to linking specific networks. If the objections or concerns can be mitigated, then fewer people would resist.
The most often heard objection to linking FM systems to D-Star seems to be that D-Star users don't want all the white noise from a weak FM station digitized and retransmitted on D-Star, and I agree with this objection. Find a way to limit the retransmission of FM signals onto the D-Star network to only good, mostly full-quieting signals and you will probably overcome these objections. Echolink and IRLP were a match because they both use the same mode, FM. Linking one type of digital system to another won't have this specific problem, so I don't see why we couldn't develop this option as long as protocols in each system are satisfied. For example, D-Star sends the callsign of the transmitting station through the network. Make this happen from the non-D-Star system and the D-Star network would probably be satisfied. Otherwise, there will continue to be objections.

As I was the main user, there had to be a better way. I wasn't the only one who thought this, and a few people put their heads together and came up with EchoIRLP, which allowed the same analog endpoint to be used for both networks. With digital, there's no common medium until you get to the end user radio itself, so you either need a multiprotocol radio, or you need infrastructure which can route across networks (and willing network administrators!). At least with digital, it should be possible to transparently carry IDs from end to end, leaving only the need to cross from network to network, and transcoding the audio where necessary. If the gateways can be built out of something like the UDR, then that could push the protocol conversion as close to the edge of the network as possible, which might scale better, as well as minimising issues of "We don't want XXX on our network!". 73 de VK3JED / VK3IRL http://vkradio.com
