Ham Radio
(See also: Software-Defined Radio)
Ham Radio is an old hobby that has origins as far back as the late 1800's. It was formalized as a hobby in the early 20th century. It is an over-regulated piece of shit, but what isn't now a days.

For a fee of $15 USD you may take one or all three tests in one sitting at no additional charge. If you fail a test, you may spend an additional $15 USD to retake it. Your license is good for 10 years with a 2 year grace period to retest after expiration. You are no longer required to know Morse code for any of these tests.

Ohm's Law
| Solve For Watts | Amp2 x Ohm | Volt2 / Ohm | Volt x Amp |
| Solve For Volts | Amp x Ohm | √Watt x Ohm | Watt / Amp |
| Solve For Amps | Volt / Ohm | Watt / Volt | √Watt / Ohm |
| Solve For Ohms | Volt2 / Watt | Volt / Amp | Watt / Amp2 |
Speed of Light Is a Constant 299,792,458 Meters Per Second
Wavelength is represented in Meters as λ
Frequency is represented in Mega Hertz as f
Speed of Light c (300MM) / Frequency f (MHz) = Wavelength λ (Meters)
This is the basic formula to find full wavelength in meters for a given frequency.
Antennas
Loop Antennas are full wavelength with one element.
c/f=λ Element Length
Dipoles are half wave with two elements.
c/f/2 = λ/2 Element Lengths
Ground Planes must be at least quarter wave with one vertical and four radial elements.
c/f/4 = λ Vertical Element Length
c/f/4 = λ Radial Element Lengths
3 Element Yagi Yagis are directional antennas consisting of a boom with reflector, driven, and director elements.
c/f = λ*.495 = Reflector Element Length
c/f = λ*.125 = Boom Separation Length
c/f = λ*.473 = Driven Element Length
c/f = λ*.125 = Boom Separation Length
c/f = λ*.440 = Director Element Length

| VLF | LF | MF | HF | VHF | UHF | SHF |
|---|---|---|---|---|---|---|

Feedline
RG6 is common and cheap, but higher resistance at 75 Ohms. You should not use this.
RG58 is cheap, 50 Ohms, and perfectly acceptable for HF.
RG8X is slightly more expensive than RG58, but lower loss.
RG213 is double the price of RG58 and RG8X, but lower attenuation at higher frequencies.
RG8U is almost identical to RG213 in price and attenuation, but has lower loss per 100ft.
LMR400 is exceptional at higher frequencies as well as low. If your software radio can do 1GHz-6GHz, this is what you get.

Notes for response to radiotelegraph Q-codes: Responses to a radiotelegraph Q-code query or a Q-code assertion may vary depending upon the code. For Q-code assertions or queries which only need to be acknowledged as received, the usual practice is to respond with the letter "R" for "Roger" which means "Received correctly". Sending an "R" merely means the code has been correctly received and does not necessarily mean that the receiving operator has taken any other action. For Q-code queries that need to be answered in the affirmative, the usual practice is to respond with the letter "C" (Sounds like the Spanish word "Si"). For Q-code queries that need to be answered in the negative, the usual practice it to respond with the letter "N" for "no". For those Q-code assertions that merely need to be acknowledged as understood, the usual practice is to respond with the prosign SN or VE which means "understood". On telegraph cable networks "KK" was often used at the end of a reply to a Q Code to mean "OK" or "Acknowledged". This practice predates amateur radio as telegraph operators in the late 19th Century are known to have used it.
Radiograms
To ease congestion on the line, the ARRL has made numbered radiograms to summarize direct messages to other users. These also are primarily used on CW transmissions. Other services, including the US Military, and the police, have their own Radiogram systems that are incompatible with this. The ARRL has other forms of radiograms, but the numbered system is the most common. An example of this in practice would be saying CALLSIGN CALL CALLSIGN2 ARRL SIXTY TWO CHRISTMAS. These are what are more commonly known as "Brevity Codes"

Lightning Protection
If your antenna is outdoors, you should take precaution to prevent yourself and your gear from becoming dead. Metal antenna mounts should be grounded using 10 gauge insulated solid core copper wire. Your coax should have a lightning arrestor between the antenna and your equipment. The arrestor should be mounted near the lightning rod it's grounded to. To prevent moisture ingress, the arrestor and coax connectors should be placed in a plastic electrical box. If you have a wire dipole antenna, you should use ceramic insulators at both ends and guy rope to tie between two points.
