Re: [aprsisce] Duplicate msgs in Chat?
- Hi Lynn and List,
My opinion on this is to leave it as is.
This because of the dual routing setup at the end user.
But you might to come out for the warning message stated that user will see a duplicate message if they used two path.
Don't know about other's opinion. And that's why we have a mailing list.. :D
- Actually, the dual paths aren't the problem. I only dupe-check the
payload. The issue is that some TNCs out there (few, thankfully) add or
remove trailing spaces at whim. I've requested advice from the aprssig
as well because there are acking-ramifications that go beyond my message
