Now in downloadable MP3: The 2015 General Pool read by Bob Zeida, N1BLF
Notice: There is an error in the audio version of our pool. G7B04 - Which of the following describes the function of a two input NOR gate. The reader gives the answer as: C – output is low when either or both inputs are low. That answer is not even a choice on the possible answers. The question from the FCC question pool is below.
G7B04 (C) Which of the following describes the function of a
two input NOR gate?
A. Output is high when either or both inputs are low
B. Output is high only when both inputs are high
C. Output is low when either or both inputs are high
D. Output is low only when both inputs are high

This lecture covers HF procedures and practices, and includes a discussion of the Frequency Chart and how the bands are laid out. There are also some notes about calling CQ on HF, whether by phone operation or CW (Morse code).
Our second lecture covers digital modes such as RTTY, PSK31, and MFSK16. We tell you some interesting historical facts and listen to what a PSK31 signal sounds like. After that, we go over some of the possible exam questions.
Our third lecture covers some basics in emergency operation, and we discuss ARES and RACES organizations.
Our fourth lecture covers rules & regulations in a marathon one and a half hour session. We go over the frequencies you can use, primary and secondary users, all that stuff about music, money, and secret codes, and third party traffic. And don't even get us started on ITU regions! It's all in there, and you are hereby given permission to pause the audio whenever you want to take a break. Running time: 1 hour 31 minutes.
Our fifth lecture covers some basic electrical principles and formulas.
Our sixth lecture covers some basic electrical principles and formulas, namely waveforms and decibels.
Our seventh lecture covers alternating current concepts PEP and RMS. PEP is Peak Envelope Power, and you need to understand RMS to know how PEP is calculated. What's RMS? Hey, listen and find out.
Our eighth lecture covers different kinds of basic components, such as resistors, capacitors, and inductors and how they behave in series and parallel configurations. Notice! There is a mistake in this lecture when adding resistors in series Rt=R1+R2+R3. The numbers go like this: 10 ohms plus 100 ohms plus 1 ohm equals 111 ohms, but the audio says 101 ohms. It should say 111 ohms.
Our ninth lecture covers the questions from the pool that are related to the discussion about components in series and parallel. We cover some uses for chokes and how to calculate the value of components in various configurations. We also talk about transformers and how to figure out primary and secondary voltages on transformers.
Our tenth lecture covers reactance, impedance, and matching.
Our eleventh lecture introduces us to active components, and we talk about diodes and transistors.
Our twelfth lecture continues active components, and we talk about vacuum tubes.
Our thirteenth lecture continues active components, and we talk about integrated circuits and logic circuits as well as interfaces.
Our fourteenth lecture talks about power supplies and batteries. We learn about different kinds of rectifier circuits.
Our fifteenth lecture talks about alternative power sources. We learn about different kinds of connectors, too.
Our sixteenth lecture talks about some basic test gear. We learn about multimeters and why high impedance input is good for accurate voltage measurements.
Our seventeenth lecture talks about modes of operation. We learn bandwidth and modulation basics for a few common modes that we are likely to use.
Our eighteenth lecture talks about digital modes. We learn the basics for a few common digital modes and why we have to pay attention to transmit duty cycle when using them.
Our nineteenth lecture talks about digital modes. We learn about some basic circuits that are inside our radios!
Our twentieth lecture is about what is inside your transmitter.
Our twenty-first lecture is about what is inside your receiver.
Our twenty- second lecture introduces good grounding practice, mobile installation, and reducing interference.
Our twenty- third lecture introduces basic wire & vertical antennas.
Our twenty- fourth lecture introduces Yagi-Uda directional antennas.
Our twenty- fifth lecture introduces loop antennas.
Our twenty- sixth lecture talks about NVIS, stacking antennas, and the Beverage antenna.
Our twenty- seventh lecture talks about feedlines and matching.
Our twenty-eighth lecture talks about the ionosphere and propagation of radio signals.
Our twenty-ninth lecture talks about solar weather and how it affects HF propagation.
Our thirtieth lecture talks about scatter mode propagation.
Our thirty-first lecture talks about electrical safety.
Our thirty-second lecture talks about RF safety. We learn about working safely around RF energy and how to evaluate our stations.
Our thirty-third and final lecture talks about outdoor safety. We learn about working safely around towers and antennas and we make some final comments about the lecture series.
