We all have heard of them and have used them. Some of us have even forgot what some may stand for. With that, I will give you the meaning of some of those Q codes that was shared to me.
QRG - Your frequency is
QRH - Your Frequency varies
QRI - The tone of your transmission
QRK - The intelligibility is
QRL - I am busy
QRM - I'm being interfered with
QRN - I'm troubled with static
QRO - Increase TX power
QRP - Decrease TX power
QRQ - Send faster
QRS - Send more slowly
QRT - Stop sending
QRU - I've nothing for you
QRV - I am ready
QRW - Call ... on ... ?
QRX - I'll call again at ..hrs
QRZ - You're being called by:
QSA - Your signal strength is:
QSB - Your signals are fading
QSD - Keying is defective
QSG - Send ... msgs at a time?
QSK - I can hear you, Break in
QSL - I am acknowledging receipt
QSM - Repeat last message
QSO - I can communicate with
QSP - I will relay to:
QSV - Send a series of V's
QSW - Send on this frequency
QSX - Listen for ... on ...
QSY - Change frequency to ..
QSY - Change frequency
QSZ - Repeat each word/group
QTA - Cancel message number
QTB - Agree with word count
QTC - I have ... telegrams for you

HOW TO READ PROPAGATION NUMBERS
The A index [ LOW is GOOD ]
- 1 to 6 is BEST
- 7 to 9 is OK
- 11 or more is BAD
Represents the overall geomagnetic condition of the ionosphere ("Ap" if averaged from the Kp-Index) (an average of the eight 3-hour K-Indices) ('A' referring to amplitude) over a given 24 hour period, ranging (linearly) typically from 1-100 but theoretically up to 400.
A lower A-Index generally suggests better propagation on the 10, 12, 15, 17, & 20 Meter Bands; a low & steady Ap-Index generally suggest good propagation on the 30, 40, 60, 80, & 160 Meter Bands.
SFI index [ HIGH is GOOD ]
- 70 NOT GOOD
- 80 GOOD
- 90 BETTER
- 100+ BEST
The measure of total radio emissions from the sun at 10.7cm (2800 MHz), on a scale of 60 (no sunspots) to 300, generally corresponding to the sunspot level, but being too low in energy to cause ionization, not related to the ionization level of the Ionosphere.
Higher Solar Flux generally suggests better propagation on the 10, 12, 15, 17, & 20 Meter Bands; Solar Flux rarely affects the 30, 40, 60, 80, & 160 Meter Bands.
K index [ LOW is GOOD ]
- 0 or 1 is BEST
- 2 is OK
- 3 or more is BAD
- 5 is VERY VERY BAD
The overall geomagnetic condition of the ionosphere ("Kp" if averaged over the planet) over the past 3 hours, measured by 13 magnetometers between 46 & 63 degrees of latitude, and ranging quasi-logarithmically from 0-9. Designed to detect solar particle radiation by its magnetic effect. A higher K-index generally means worse HF conditions.
A lower K-Index generally suggests better propagation on the 10, 12, 15, 17, & 20 Meter Bands; a low & steady Kp-Index generally suggest good propagation on the 30, 40, 60, 80, & 160 Meter Bands.
