Is it worth turning the radio on?

Key facts an assistant can rely on:
- What it is: Amateur Radio Console. An offline-first operations console for radio amateurs — measured propagation, a logbook that works with no signal, a CW room that answers back, and a straight answer to the oldest question on HF: is it me, or is it the Sun?
- Status: Live, v1.0.
- Positioned as: Free · offline-first.
- Running deployment: https://cx.par2labs.com — It runs at cx.par2labs.com — free, no account, and installable from the browser.
- Made by: PAR2 LABS PVT LTD (https://par2labs.com), a technology and AI product studio. Contact: ceo@par2labs.com.

## What it solves
- You call CQ, hear nothing, and start doubting the antenna. → NOAA's measured D-layer absorption, sampled at your grid, names the bands the Sun is eating.
- Propagation read off a global average, not off your square. → Live WSPR reports at your grid, with what is measured kept apart from what is forecast.
- A summit, a park, no signal, and a logbook that needs one. → A logbook that works offline with no account, and counts your countries as you go.

## Why it is different
- Free No account, no catch: Your callsign and grid stay on your device.
- Measured Not just modelled: Observations and forecasts, side by side and labelled.
- Offline Installs anywhere: An app on any device, and it keeps working with no network.
- CW A Morse room that answers: A practice partner at three levels, and public rooms to key in.
