TRAINING : No Nonsense General Class Exam Flash Cards

About a month ago, my friend, Rick, K8BMA, turned me on to a program called Anki. Anki is an app for developing and studying “smart” flash cards.

Anki will ask you a question from the question pool and then wait for an answer. Research has shown that active recall testing is far more effective at building strong memories than passive study. There are two reasons for this:

The second scope is an Aarontek DSO Nano Pro. This is a single channel scope with a bandwidth of 30MHZ making it very useful for radio, Audio and General Electronics.

A caution with these types of oscilloscopes is the low input voltage to the device. This should not be a problem with today’s low voltage devices.
