What is this Triple Knickle?

On a technical level, the Triple Knickle is what we who use it in the Central Valley call the FM simplex frequency 147.555. Operating simplex has a number of advantages, chief among them, simplicity.

On a social level the Triple Knickle is an organizing concept. Because the reach of simplex is extremely local, having a frequency like 147.555 as a common talk frequency gives operators in your area a place to go where they are likely to meet up with fellow enthusiasts. If you expand that concept across multiple areas now you have a home frequency to meet new amateur radio operators as you travel.

Ultimately the Triple Knickle is about meeting new people, sharing information and having a good time.
