Check back this page for Spring Branch Radio changes.
We only need enough information to get radios distributed to
participants, plus a commitment
to participate and pass the radio on to another coverage area
resident or back to a Coordinator if you move.
(On the air or Nextdoor.com)
Initial repeater operation is simplex, parrot or talk-back repeater. Repeater records voice message or announcement and plays it back immediately. Duplex repeater is desired but, with inexpensive radios the simplex repeater has better efficiency and will provide for Neighborhoods Project emergency communications.
Little magnetic mount antennas (to steel like refrigerator, filing cabinet or even a steel pie plate), help a lot in fringe areas. Work well with 15 channel UHF standard radios with removable antenna, Let us know, free.
