SIMPLEX

SIMPLEX is a niche tool handy for users whose hobbies include playing around with radio hardware. Simplex is a type of transmission that sends information in a single direction. Just how walkie-talkies work. The program allows for an elevated form of control over simplex or duplex radio repeaters.

Simplex repeaters transmit information in short bursts only. SIMPLEX allows one to add more depth to the process by providing recording and replay commands.

Determine a recording's length, the silence interval, and the best channel for its output. The replay length can also be changed. Type in the number of seconds you find necessary and adjust the sound levels while at that.

One can create a digital file based on a record. Use the Ctrl+W hotkey to export a specific record to a Wave file, also known as WAV.

Simple might be the name of the game, but the application is not limited to that system only. To be more precise, SIMPLEX works with duplex, transponder, and even mixed repeaters. Also, when in duplex mode, the utility emulates a classical duplex repeater, which removes the need for an actual rig.

Use the Mode combo menu to cycle between transmission types. If you want to go more in-depth about how the modes work, the program's documentation should quench any curiosity.

To summarize, SIMPLEX sounds simple, but it's not. Despite its hobbyist nature, amateur radio looks like rocket science for the average Joe, and for that reason, SIMPLEX is reserved for a specific audience. Not to scare away new users or those wishing to experiment with such an application, but prior information is required to make sense of the app.
