Hi Mooneer, Matt and all, We in Australia have both vast areas and valley locations where VHF/UHF and cell-phone systems
are not usable, but comms to HQ is still needed. So, our NSW country ambulances are NOW fitted with HF Digital radios with the TWELP (r) protocol. Here in Australia, we have the ACMA who sets our regulations. We hams negotiate with them via our WIA. Can I ask you amateurs in, whatever country, to ask via your ARRL etc. your FCC etc. to reconsider "HF repeaters", as these regulations stem from the WWII years? That's what I've been asking for the last year but not spelling it out directly. "digital" means, a receiving device CAN determine what is needed to be done with this signal or data stream. This technology was not practical back before available microprocessors. Alan VK2ZIW On Thu, 6 Jan 2022 10:52:49 -0800, Mooneer Salem wrote > Hi Matt, > > I think it might depend on the area.
