VHF / UHF Radio Field Planner

Thank you for using VHF/UHF. This app is built for operators who want a cleaner way to plan VHF and UHF paths, organize station records, check antennas and power, prepare field kits, and keep useful notes close at hand. It is practical, local*first, and focused on the details that matter before you transmit, travel, set up a station, or troubleshoot a contact.

VHF/UHF brings radio calculators, station records, checklists, reference tools, and local backups into one workspace for amateur radio, GMRS, scanner monitoring, field operations, and repeater planning.

Plan radio paths:
* Estimate RF line-of-sight distance from antenna height.
* Compare map distance, bearing, and reciprocal bearing between locations.
* Check terrain, obstruction, path loss, and Fresnel clearance.
* Convert common distance units used in radio planning.
* Work with miles, kilometers, feet, meters, watts, dBm, and dBW where they make sense.

Use practical RF calculators:
* RF power, gain, feedline loss, output, EIRP, and dBm.
* Line-of-sight and radio horizon estimates.
* Terrain ray trace for a single obstruction.
* Map distance for station*to*station planning.
* Converter workspace for field planning units.
* Morse converter and additional radio utilities.

Build a local station notebook:
* Save radios, antennas, locations, computers, connections, transmit profiles, and receiver profiles.
* Track contacts, notes, sessions, checklists, QSL status, and station follow*up.
* Link radios, antennas, and locations so your records reflect how your station is actually used.
* Search saved records, tags, grid squares, notes, and local reference content.

Stay ready in the field:
* Use helpful checklist templates for repeater programming, field kits, antenna work, mobile checks, portable operation, and session follow*up.
* Track station milestones and levels from the More tab.
* See which station setup steps are complete and what to do next.
* Keep backup readiness visible without turning the app into a spreadsheet.

Keep your data under your control:
* No account is required for calculators, local records, checklists, search, or export.
* Records stay on your device unless you export or share them.
* Free backup export is included.
* Pro unlocks backup import, restore validation, advanced planning, and unlimited station records.

VHF/UHF is useful for:
* Ham radio operators planning 2m, 70cm, simplex, repeater, and portable contacts.
* GMRS users comparing locations, antennas, and field setups.
* Scanner listeners organizing receiver profiles and notes.
* Emergency communicators preparing radios, power, antennas, and checklists.
* Field Day, POTA, SOTA, event, club, mobile, and home station planning.

Why operators keep it nearby:
* Fast checks for everyday radio questions without opening a pile of separate notes.
* A station record system that fits radios, antennas, locations, computers, receivers, and transmit profiles.
* Practical reminders for power, feedline loss, line of sight, map distance, and backup readiness.
* Local search that helps you find the contact, note, radio, location, or checklist you saved earlier.
* Field friendly organization for the operator who wants less clutter before the next net, trip, activation, or install.

VHF/UHF does not replace official rules, local coordination, equipment manuals, RF exposure review, or sound operating judgment. It gives you a focused workspace for planning, recording, checking, and backing up your radio work so you can spend less time hunting through scattered notes and more time operating with confidence.
