Lesson 18: General Class Exam Course G4D

Here is lesson 18!  This lesson covers the G4D questions dealing with speech processors, connectors, and S-meters.  There is some memorization in this lesson, but it is not too bad.  The information you need to focus on is:

- Speech processors increase the average power of your signal, but not the PEP.
- An S-meter reading of 20 dB over S9 is 100 times stronger than a signal at just S9. (I dorked up the question in the video.  Disregard the formula.)
- A Type-N connector is a moisture resistant RF connector that is useful up to 10 GHz.
- A DB-9 connector is a good connector for a data serial port.
- UHF connectors is a family of RF connectors that have nothing to do with UHF.  They are useful up to 150 MHz.

And that's it!  If you have any suggestions, comments or questions, please feel free to leave them in the comments box.  Thanks!
