La CB de 27 MHz: cuando comunicar era un acto libre.
Sin servidores, sin algoritmos, sin cobertura perfecta. Solo voz directa. Camioneros, viajeros y ciudadanos compartiendo ayuda en tiempo real. Recuperarla hoy es volver a una comunicación humana y resistente.

Aí que tá, por que 27MHz precisa de uma antena enorme

The white powder is zinc-based anti moss. The rest is antenna for 27MHz (CB band)

Go back in time and use an old-fashioned 27MHz CB radio, not mobile phones.

So then we all (the locals kids) went and got 27MHz CB radios and soon had our own network across Greensborough, Montmorency, Eltham etc) Channel 18, on 27MHz CB 'the Greensborough' channel.

When we got cut off we kids found a way around it. That was the 1980s and 90s. Social media ban? lmfao.

Go back to old school systems. Make it more difficult for the US government to track. Go back to 'made up' callsigns on 27MHz and they won't have a clue who you are, nor where you're transmitting from.

Then use the good old 27MHz CB AM/FM/SSB radio instead rather than cell networks. They can't track anything so easily then. They'll need the FCC and direction finding (DF) and triangulation of radio signals.

Much harder than just tapping into cell towers.

Scutters worst actors in the world. Dodgy servos, issues with 27MHz. Not good.

...up in post-production).

Some scenes - Ectomorph? - shot in the gantry areas of Studio A, Manchester, Oxford Rd, for a sense of 'extensive spaceship with wiring'...

Scutters a pain in the arse: 27MHz R/C with no mind of their own and dodgy servos.

Guess what? My amateur ham radio is a more reliable way of getting urgent police/fire/ambulance than relying on 000 (Australia's 911 for our American followers).

So my ham radio is more reliable than Telstra or Optus in an emergency now.

Probably have more luck on 27MHz CB Ch 9 than calling 000

Qui... Less than busy at the marine rescue radio base this evening. Got plenty of IT admin work and updates to an equipment training manual to do.
Inside the Port Stephens Marine Rescue Ops Room. Three operator stations, each with a touchscreen Radio-over-IP and ops PC, Cisco CP-8851 VoIP phone, a choice of desk pedestal mic or headset. Other equipment includes a Surf Life Saving handheld transceiver, backup VHF DSC Marine radio, backup Marine Rescue Discrete Communications Network (DCN), 27MHZ Marine radio, Rhotheta VHF/EPIRB Radio Direction Finder, Koden 27Mhz Radio Direction Finder, Medical Alert Receiver, NTP PoE Clock, and an old school barometer.
