Everything you need to get on the air

Curated tools for ham operators — work out what your station can reach, find the repeaters and nets near you, and cut an antenna to length. No account needed.

New · Station Capability Bench

Tick what you own. See how far it reaches.

Every activity in amateur radio is a chain — a radio, an antenna, sometimes a computer, and a licence that permits it. Tick your gear and the chain either completes or it doesn't, on a live map centred on your own town.

  • 29 activities scored against your actual station — ready now, one step away, or blocked, and it tells you which of the two it is.
  • Every repeater in range, with listen and transmit frequencies and tone — exportable straight to a CHIRP codeplug.
  • Eight countries of licence classes, so the answer changes with your privileges rather than assuming everyone is VU.

No account needed. Your station is saved in your own browser, and you can share a link to the exact configuration.

Illustrative. The bench computes these from the gear you tick, your grid square and your licence class — distances are typical working ranges, not records.

Don't have a callsign yet? Here is the whole exam.

A complete course for the Indian ASOC (Restricted) examination — the licence that makes you a VU3. It starts at what a volt is and ends at the exact wording of the rules you will be tested on. Written to hand a new operator, up front, what most of us picked up years later.

  • 36 lessons covering every clause of the published syllabus, written for someone with no electronics background
  • 470 practice questions, every one with the reasoning — and a note wherever an answer is commonly misremembered
  • Timed mock exams marked the way WPC marks them: 40% in each section and 50% overall, or you have not passed

Everything is free and nothing is uploaded. Your progress lives in your own browser.

Built against the published WPC syllabus and the Telecommunications (Amateur Services) Rules, 2024, which replaced the 1978 Rules in October 2024. Where the syllabus still names the older Rules, both are taught.
