SafecomLink Cluster: Multi-Band ARQ Networking for PACTOR
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.
