Radio Beacon for Voice and Morse Code, Simplex
Repeater and Repeater Controller.
Voice repeaters need to have an automatic Radio
Beacon to identify them in Voice and Morse code. This way, users are informed of
the location of the repeater, and to whom it belongues, among other useful or
technical informations.
PrimeHERTY may also work as a Simplex Repeater, eg, when it detects incoming
audio, records it, and retransmits it as soon as the incoming audio stops. Using
a monoband radio, one can do an economical and easy to use Simplex Repeater.
If a Full-Duplex radio is available, or two distinct radios, PrimeHERTY may also
control them, behaving like a Repeater Controller. In case of having a
Full-Duplex radio, PrimeHERTY receives its incoming audio, activates PTT, and
returns in real-time the audio being received. Having distinct radios, the
process is exactly the same: one receives, the other transmits.
PrimeHERTY may be connected to any radio system, transmitter or
transceiver, or to any audio system.
Transmition modes, power connection and voice recording may be chosen by the use
of DIP swiches mounted on the PrimeHERTY board.
Voice/audio recording is done whenever it is desired, for there is a microphone
available for that end on the PrimeHERTY board. Audio signal levels may also be
adjusted by the use of potentiometers available.
PrimeHERTY energy may be supplied from three different sources: external power,
internal batteries or solar pannel.
Setup is done with the help of a Computer, running a standard terminal program (eg:
HyperTerminal for Windows, goSerial for MAC or Minicom for LINUX, among others).
One may program the Morse phrase to transmit, as also the delay between
transmissions.
