Bonus Question -- 1923


1. b -- Know this ratio by heart!
2. a -- A USB signal's carrier, displayed by the transceiver, is just the lower edge of the signal!
3. d -- Official Observers are the backbone of Amateur Radio's self-policing history.
4. a -- Most coaxial cables with a polyethylene center insulator have this velocity factor.
5. a -- The lower the resistive loss for the circuit's components, the sharper the frequency response becomes.
6. b -- 3rd order products are the most troublesome because they are strong and close to the frequency of the signals creating the intermodulation
7. d -- Silver indicates 10 percent value tolerance, gold 5 percent and no band 20 percent.
8. b -- DX stations often transmit on a single frequency, while listening one or more kHz away to help speed things along (answer c isn't too bad, either...).
9. c -- Baluns (balanced-to-unbalanced transformers) are often used to drive these loads.
10. a -- This is also the product of wavelength in meters and frequency in MHz.
11. d -- Amateurs are limited to 50 W ERP (Effective Radiated Power) on 60 meters
