Getting started

FreqSense works from two facts: the country you are in and the gear you are carrying. The spectrum picture, the safe windows and the coordinated channel list all follow from those two choices.

Quick start

1. Open FreqSense from the dashboard. It needs a tablet or laptop.
2. Set Region / Regulatory Framework to the country you are physically in. The spectrum redraws with that region's TV channels, cellular blocks and licence-free ranges.
3. Under Manufacturer / Band Filter, type your brand, pick the Band / Model and press + Pin to spectrum. The band's tuning range appears as an overlay, so you can see whether it even reaches clean spectrum.
4. In Coordinate N Channels, set N (channels) and the Channel spacing, then press Coordinate. The packer fills the table with frequencies that avoid occupied channels and 3rd-order intermod hits.
5. Type the Talent and Role for each row so the sheet reads like a show.
6. Open Saved plans and press + Save current. Plans sync to your account, so the plan you build on the laptop is on the tablet at the venue.

The screen

• Frequency Spectrum — the main drawing. Zoom presets: PMSE (470–694), UHF (470–960) and Full (400–960). Hover for the channel tooltip, click to pin it, or step through channels with the arrow keys. The legend separates Whitespace (safe), Occupied / 5G, 4G / 5G Cellular, Intermod / Protected and Scan trace.
• Regulatory Status — country, authority, status and notes for the selected band. Badges read Free, Required (a licence is needed), Partial, Prohibited or Outside.
• Safe Coordination Windows — a card per clear gap with its width and how many channels fit at your spacing. See Find safe windows and coordinate channels.
• Field Notes — six practical cards, collapsed by default.
• Live SDR and scan import — see Import a scan or connect an SDR.

Core concepts

• Region is a legal choice, not a preference. Band plans, licence status and duplex gaps differ per country. Germany, for example, ends licence-free UHF PMSE at 694 MHz and offers the 823–832 MHz duplex gap as a usable window; the German plan is written up at /rf-cheatsheet/funkfrequenzen-deutschland.
• Windows are the gaps left after occupied channels, guard bands and scan-flagged ranges are subtracted, sorted widest first.
• Intermod products are where your own transmitters mix and land on another channel. The packer avoids 3rd-order hits; higher-order and TX-on-RX hits are flagged for you to judge.

Saved plans, your theme, the colour-blind-safe pattern overlay and the tool language follow your account. If a plan from another device arrives while the page is open, a toast says Account data arrived — reload to see the latest.

Next

• Find safe windows and coordinate channels — windows, packer and intermod in detail.
• Import a scan or connect an SDR — bring the venue's real noise floor into the plan.
• Export to WWB, WSM and paper — hand the plan to WWB, WSM or paper.
