Does anyone know the alphanumeric for the question

[KC7JTY]

I believe there are the words duty cycle in the question and one of the answer selections has something to do with doing close in RDF work?
I'm grasping at straws here.

RDF is probably radio direction finding (without looking at the exact question).

Duty cycle-"Operating parameters of a cell or battery including factors such as charge and discharge rates, depth of discharge, cycle length, and length of time in the standby mode."

"The ratio of "on" time to "off" time for an electronic component or signal. In a power system duty cycle is typically used in reference to the semiconductor switch (in PWM controlled systems) or clock signal."

Haven't looked at the exact question but I hope those are helpful.

32. What effect does duty cycle have when evaluating RF exposure?
A. High duty-cycle emissions permit greater short-term exposure levels
B. The duty cycle is not considered when evaluating RF exposure
C. Low duty-cycle emissions permit greater short-term exposure levels
D. Any duty cycle may be used as long as it is less than 100 percent

17. For which of the following applications might you use a field strength meter?
A. A keying indicator for a RTTY or packet transmitter
B. An overmodulation indicator for a SSB transmitter
C. A modulation monitor for a frequency or phase modulation transmitter
D. Close-in RDF work

I hope that helps #

Why not try grasping at a book instead?

This is the one I was thinking of.
I'll have to find it in the q & a pool.
Thanks
I answered A. is that not correcto?

[KC7JTY]

The part about duty cycle was just to throw everyone off
thanks all

Yep...I blew it. The only answer I got wrong. Would have helped to know what RDF was?

Yeah, its a real pain in the butt to learn about amateur radio activities that you have no intention of using!

I will give you a hint: the R in RDF stands for radio!
