A radio plan should survive a bad day.

Direct amateur-radio plan

Voice Alert is deliberately narrow.

The public doctrine retains APRS Voice Alert because the TM-D700A still implements it usefully. It is not treated as a universal feature of newer APRS radios, and 144.390 MHz is never used for an extended voice QSO. Alert, identify, name the QSY, move.

Family GMRS fallback

GMRS Channel 6 with DCS 073 is the family fallback specified in the public doctrine. GMRS is a separate service and is not used in Mexico.

Hotspot frequencies are not simplex voice channels.

433.775 MHz and 145.670 MHz are bridge or hotspot access frequencies in the Team Stone system. They should not be presented as ordinary direct family voice channels.

Keep the services legally distinct.

Amateur radio, GMRS, marine radio, aviation and public-safety monitoring, cellular service, and internet-linked systems each have different authorization and operating rules. The doctrine labels transmit, receive-only, and linked access accordingly.

Antenna handling: Every fixed antenna path provides a DC or static-drain path to ground. All fixed antennas except the 80-meter loop are fully DC grounded through their antenna and/or switched-feed arrangements. The loop is not fully DC grounded; its lightning arrestor and grounded shunt provide its static-drain path. Those arrangements help discharge static, quiet receiver noise, and support the station’s overall lightning-safety system; they are not a claim of lightning immunity. Shared feed lines are treated as one-radio-at-a-time paths unless a purpose-built RF device says otherwise. Portable antennas still require deliberate feed-line, grounding, switching, weatherproofing, and strain-relief discipline.

Public and private layers

Public releases may include principles, publishable frequencies, equipment roles, road and field preparation, and printable references. Private annexes hold credentials, exact contacts, sensitive routines, infrastructure, and family information that should not be indexed.
