• "Q" codes:
  QRL - is freq in use?
  QRM - receiving interference from other stations
  QRN - I have static
  QRP - low power transmission
  QRS - send CW slower
  QRV - I’m ready to receive
  QSK - full break-in telegraphy
  QSL - I acknowledge receipt
  QST - calling all stations
  QSY - changing frequency

  KN listening for only certain stations
  C (RST) chirpy or unstable CW signal
  AR end of formal CW message

• List of HF ham frequencies and generally accepted ie. voluntary modes to use: (link to:) ARRL
  
  
  
  
  

• Legal Frequencies and Modes for General Class Licensees:
  
  

  However this chart does not tell the whole story, because it does not list allowed frequencies above 50MHz.

• Calling frequencies:
  • 70cm: 446.000 (FM)
            432.100 (SSB)
  • 2m: 146.520 (FM)
            144.200 (SSB)
  • 151.820 un-official MURS calling freq
  • 6m: 50.125
  • 10m: 28.400
  • 20m: 14.300 USB

• Local frequencies of interest:
  162.400 NOAA weather
  154.830 Wasco county sherrif dispatch
  155.01 City of TD police dispatch
  151.940 most common emergency freq
  156.800 global distress freq (monitored by Coast Guard)

  
  145.975 AO-7 beacon 09/25 – 12/26
  St Vincent: 3.815 LSB & 7.188 LSB

• MURS frequencies: - no license required?
  Channel Frequency Channel name
  1 151.82 MHz MURS 1
  2 151.88 MHz MURS 2
  3 151.94 MHz MURS 3
  4 154.57 MHz Blue Dot

• Nets:
  • Monday 8pm 444.700 Stacker GEAR check-in net

• Local (Col Gorge) Repeaters:
• Propagation:
  • 6-meters:
    Best at sunspot maximum, with solar flux 150 - 200, via F-layer skip
    May - Jly "sporadic-E" can work well (peak at solstice in June) (openings typ last a few hours)
    auroral, meteor-scatter, transequatorial and moonbounce can also be used
  • HF waves must pass through the D layer on their way up to be reflected by E or F layer to come back and give long-distance, over-horizon communication. They pass through the D layer both on the way up and again on the way back down. If the D layer is "active" then it will attenuate the signal passing through and propagation is worse.
• digital modes
• CB radio:
  HF, 26.9650 MHz to 27.4050 MHz (40 channels), power output is 4 watts for AM and FM and 12 watts PEP for SSB.
  Channel 9 is reserved for emergencies, and channel 11 is a calling channel.

• Logging:
  • QRZ
  • Log Book of the World
