I'd be happy to help with this package. I'm not sure if I can immediately sign up as maintainer -- I'm an ex-DD, and while I've re-applied for project membership, for now I would need someone from debian-hams to sponsor my uploads. I'm interested in doing the work, though.
I've submitted a trivial merge request on Salsa to bring some aspects of the packaging up to date: https://salsa.debian.org/debian-hamradio-team/wwl/-/merge_requests/2/commits -Chris
