AetherSDR — Open-Source Linux Client for Flex Radios

Hey Jeremy, great work on AetherSDR — this has been a long time coming for the Linux community.

Noticed you added a CW decoder for giggles in v0.4.13. I've been working on something that might be
worth a look before you go too far down that road. It's called OpenSkimmer — an open source Linux CW
skimmer I've been building with Claude as a co-developer (looks like we had the same idea there).

Quick tour:

- Full 192kHz band coverage via a polyphase filter bank channelizer — monitors every CW signal in the
band simultaneously, not just the active slice
- Three-decoder ensemble: uhsdr_cw (Goertzel, same core SkimSrv uses), libbmorse.so (Bayesian trellis,
AG1LE's decoder), all in C++
- Scores 56/67 on a dense CWT contest pileup benchmark — lightyears ahead of anything else available on
Linux open source
- GPLv3, so the licensing lines up perfectly with AetherSDR

The IQ stream from the Flex via VITA-49 is exactly what the channelizer eats, so integration into
AetherSDR would be fairly natural. What ggmorse gives you is a solid single-slice decoder — what this
adds is full-band skimming, which is a different beast entirely for contest and DX work.

Still actively developing but it's in good shape. Happy to connect and share more if you're interested.
