Tools for
the shack.

Tell it which bands you want and how much room you have. It suggests antennas that fit, gives cut lengths and feed-point matching, then tells you how much to trim from your analyzer readings.

Learns which characters and speeds trip you up and drills those harder, working up to realistic contact and contest copy under noise, fading, static crashes and a nearby station. Koch or Farnsworth. Sending practice grades your timing.

Every question in the official Technician, General and Amateur Extra pools. Practice exams in the real format, study by topic, and drills that keep coming back to what you miss.

Which bands are open from your grid square right now, and to where, from live reception reports and space weather, with a world map and an outlook for the next few hours. Defaults to metro Atlanta.

Plug a software-defined radio dongle into your computer and it watches a band for you: records the noise floor over time, flags new or unusual signals, and keeps a week of waterfall history. Needs Chrome or Edge.
