q signals
Q-signals
  • The use of Q-signals began in the days of the telegraph, where operators developed a way to exchange commonly transmitted information (location, output power, etc.) more efficiently.
  • Q-signals are a kind of “short-hand” hams use to communicate quickly, especially via Morse Code.
  • Most Q-signals can be used as a question or a statement:

“My QTH is Georgia.”

“What is your QTH?”

  • Some common Q-signals are on the next slide…

HPST Technician Course

q signals1
Q-Signals

QRM - Is my transmission being interfered with?/Something is causing interference

QRN - Are you troubled by static/noise?/I am troubled by static/noise.

QRO - Shall I increase transmitter power?/I am running high power.

QRP - Shall I decrease transmitter power?/I am running low power.

QRQ - Shall I send faster?/Please send faster.

QRS - Shall I send slower?/Please send slower

QRT - Shall I stop sending?/I am going off the air.

QRZ - Who is calling me?

QSB - Are my signals fading?/Your signal is fading.

QSL - Can you acknowledge receipt?/I received the message.

QSO - Can you communicate with ____ direct?/I will communicate with ____ directly.

QSY - Shall I change frequency?/I am changing frequency to _______.

QTH - What is your location?/My location is _______.

HPST Technician Course

the rst reporting system
The RST Reporting System

The RST system is a quick way amateurs use to describe a received signal.

Readability 1 = Poor 5 = Good

Signal Strength 1 = Poor 9 = Good

Tone (CW only) 1 = Poor 9 = Good

Signals stronger than S9 are reported as “XX Db over S9”

Note: Do not use the RST system on repeaters.

Strong FM signals are referred to as “full quieting”

HPST Technician Course

finding repeaters
Finding Repeaters
  • To find a repeater:
    • Check the band plan to see what segment is set aside for repeaters
      • Tune through that segment
    • Listen for conversations or repeater ID
      • ID may be in voice or Morse code
      • Good reason to learn the code
    • Scan the repeater band segments (radio should have scan feature)
    • Use a repeater directory (paper or online)

HPST Technician Course

using repeaters
Using Repeaters
  • Find frequency (such as 146.730)
  • Set offset (-600 kHz)
  • Set sub-audible tone (CTCSS)

  • Key and say “<call sign> listening”
  • Observe repeater output signal on your S-meter
    • Squelch tail

HPST Technician Course

repeater id and control
Repeater ID and Control
  • ID
    • Repeater will ID at least every ten minutes
  • Timer
    • Normally 3 minutes, kills transmitter
    • May announce “Time Out”
    • Will reset when carrier goes away
    • Reset during long conversations by unkeying until courtesy tone
  • Linking
    • Some repeaters are linked (audio sharing)
    • Wide area coverage

  • All repeaters are required to have a 3 minute transmit time-out feature. This applies to the autopatch as well.
  • Do not abuse the autopatch.
  • Use judgment calling 911.
  • Use of autopatch may be subject to payment of dues to the repeater owner or club.

HPST Technician Course

open special use private repeaters

repeater coordination
Repeater Coordination
  • Who Decides?
    • Volunteers!
    • Several repeater “coordination groups” throughout the US
    • SERA Southeast Repeater Association for our area
  • Input vs. Output “pairs” of frequencies are coordinated
  • Coordinators determine what freq is best based on location, HAAT, power, etc. to avoid interference with other repeaters
  • The FCC will typically side with a coordinated repeater over a uncoordinated repeater

HPST Technician Course

simplex frequencies
Simplex Frequencies
  • Band plans provide blocks of “simplex” frequencies
  • Direct communication, no repeater required
    • Establish contact on the repeater
    • Check input frequency to see if you can hear the other station
    • If so, move to a simplex frequency
