The following is a message from SafecomLink:

For decades, HF radio ARQ digital modes such as PACTOR has been governed by two “laws” everyone simply accepted:

❌ ARQ is point-to-point.
❌ Both stations must be on the same band with a viable propagation path.

BUT what if neither of those limitations were actually true anymore?

Imagine:

🔹 A station on 40m having a live ARQ conversation with a station on 20m.
🔹 Operators on completely different bands exchanging data in real time.
🔹 Three, four, or even more stations participating in an error-free ARQ live chat.
🔹 An HF network where propagation barriers become routing opportunities instead of dead ends.

This isn’t a future concept.
It’s already happening!

The SafecomLink Cluster for PACTOR introduces something that has never existed before in HF ARQ data communications: a shared “”connected brain”” that bridges multiple independent nodes into a single intelligent system.

The result is a capability that fundamentally changes how we think about HF data networks.

🔴 Is it a repeater?
🔴 A router?
🔴 A bridge?
🔴 Or something entirely new?

We recently documented the concept, architecture, and real-world use cases in a short case study.

If you’re involved in HF digital communications, emergency communications, Pactor, Winlink, or simply enjoy seeing old limitations challenged, this may be worth 5 minutes of your time.

What would YOU build if HF Radio ARQ digital mode was no longer limited to a single band and a single peer? 🚀
