I've been reading up on HERMES and it looks like an interesting backcountry / maritime relay system even for places like the US. Can you just get two units, pair them together, and establish a bridge? I'd love to integrate that with NNCP for getting email in the woods without the expense or power draw of a Starlink terminal. And if you're still looking for a GitHub replacement, I recommend SourceHut.

But not in the US. In HERMES the plan here is to have it with NNCP in the future. If you want to test such setup in the US, I think it would not be difficult, but be aware the hams in the US don't like to hear the word encryption, so I feel better get another type of licensing model to operate in woods / places without telecom coverage / telecom blackouts. I would not know the precise service, but in ITU frequency chart they are named fixed/portable/mobile wireless services, and there pretty a lot of bands allocated for those in HF. Even the most affordable amateur radio transceivers will operate outside ham bands (usually just a small modification), or, of course, professional rigs will operate by default in all HF bands, We use the sBitx radio for our deployments, which are wideband, affordable, can run all email setup, modem, nncp in the raspberry pi inside, and can cover most the HF band as whole (we got licenses in Brazil, for example, in the 5 MHz and upper 7 MHz). Btw, I created a further optimized nncp branch with less overhead, after the last email of Sergey which pointed to other places where padding is done (tks Sergey!), but this is not ready for upstreaming, as it breaks compatibility with v3 protocol (adds a v4 but keeps compatibility with v3, as of now): https://github.com/Rhizomatica/nncp/commits/pktv4-variable-path/ Thanks for the repo at https://git.sr.ht/~tidux/nncpnet ! Very useful when I start migrating the email services!

Great! Merged into develop branch. If you have got other additional commits and documentation update, if HFmodem is ready to be publicly released then let me know. -- Sergey Matveev (http://www.stargrave.org/) LibrePGP: 12AD 3268 9C66 0D42 6967 FD75 CB82 0563 2107 AD8A [-- Attachment #2: signature.asc --] [-- Type: application/pgp-signature, Size: 265 bytes --] ^ permalink raw reply [flat|nested] 7+ messages in thread

Hi Sergey! I let you know, definitely, thanks for your support! At this point it is fully functional. We of course need and will carry more over-the-air tests to make sure everything is working as expected and also explore other features like nncp-bundle in broadcast context to see if all works well.

At 87 BPS, transmitting 65 KB of padding takes over 12 minutes. A per-node configuration option to skip this padding would make connection establishment practical over HF. ?
