This is a list of topics I had to commit to memory when studying on HamTestOnline.com for my General Amateur Radio License.

General Class Frequency Privileges:

Overall:

 

Specific General Class Frequencies to Remember for Test:

Specific General Class Frequencies to Memorize

  • Phone and images not permitted on 30 m band.

Crossband Repeater:

  • The FCC regulations limit repeaters in the 10-meter band to the frequency range 29.5-29.7 MHz.

Transmitter Power:

  • No station may transmit with a transmitter power exceeding 1500 watts PEP. 
  • No station may transmit with a transmitter power output exceeding 200 W PEP on the 30-meter band (10.1-10.15 MHz).

Maximum Symbol Rate:

Band Plan:

  • DX Window: Range of frequencies for DXing outside of contiguous states. An example is: 50.1-50.125 MHz
  • 80 m band digital contacts occur in RTTY/Data (3.570-3.60 MHz)
  • 20 m digital contacts RTTY and packet (14.070-14.112 MHZ)
  • 20 m PSK31 contacts below RTTY segment (< 14.070 MHZ)

 

SSB: Upper vs Lower

  • LSB for frequencies below 9 MHz (160, 80 and 40 m)
  • USB for frequencies above 9 MHz (20 m and  shorter including VHF and UHF)

Exceptions

  • USB on all five channels of 60 m
  • LSB is always used for RTTY and AFSK
  • USB is always used for certain digital modes (PSK31, JT65, JT9 or FT8 on AFSK)

Formulas:

  • P = E * I
  • P = E/ R
  • P = I2 * R
  • Evrms = sqrt(P * R)
  • Vrms  = Peak V * .707, where peak is taken from oscillator, if peak to peak divide by 2
  • PEP = (Vrms)2 / R
  • 1/2 Wavelength = 468/Mhz, if 1/4 half numerator
  • Low Dev = Freq. Dev / (Freq / Low Freq)
  • Bandwidth = 2 * (Dmax + Mmax)
  • Db Loss = 10-(Db Loss / 10)
  • Sum Resistors and Inductors in series.
  • Sum reciprocal Resistors and Inductors in parallel.
  • Sum Capacitors in parallel.
  • Sum reciprocal Capacitors in series.
  • Transformer = Np/N= sqrt(Zp/Zs)
