FreqSense

FreqSense plans the wireless frequencies for a show. Pick the region you are standing in and it draws the spectrum: occupied TV channels, cellular blocks, guard bands and the licence-free gaps. Add your channels, and it finds the safe windows, flags intermod products and prints a coordination sheet.

Who it is for

• FOH and monitor engineers coordinating mics and in-ears before the truck leaves.
• Freelance techs who meet a different brand of receiver every week.
• Touring crews crossing borders who need several countries' rules in one place.

What makes it different

• Vendor-neutral. It does not care who made your receivers — and it still imports and exports Shure WWB and Sennheiser WSM plans.
• Eight regulatory regions. DE, UK, US, EU, FR, JP, AU and CA, each with its own band plan and authority table.
• Real scans. Drop in an RF Explorer, WWB or R&S FSH trace, or connect an RF Explorer over WebUSB for a live view.
• Field notes built in. Six cards on antennas, squelch, intermod, batteries, workflow and regulations — also published at /rf-cheatsheet/field-notes.
