## What is 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.

For subscriptions:
Monthly Pro is a 1-month auto-renewable subscription.
Annual Pro is a 1-year auto-renewable subscription.

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.

### 5/5 — Works well for notes and calculations

*2026-07-15*

I’ve been using this to organize my ham radio station and it helps for getting several calculations including line of site set up for packet

### 1/5 — Not what I expected

*2019-03-08*

I thought I was buying an app to help improve my alignment between Ariel and Antenna, but instead I needed to input information that I didn't understand.

### 5/5 — Great for ham radio

*2018-07-20*

Does exactly what it says it will

### 5/5 — NMSCAS

*2013-10-04*

Great app. Use it for EIRP, power and line of sight Distance.

### 3/5 — Antenna Line of Sight Calculator

*2012-01-10*

Wish it had gain figures for antennas to calc ERP.

## Version history (last 5 releases)

### 8.0 — 2026-07-15

Thank you for using VHF/UHF and for giving your station planning the kind of attention it deserves. This update focuses on making the app cleaner, more practical, and easier to trust during real radio work. The goal is simple: fewer confusing screens, clearer records, better calculator inputs, stronger backup handling, and a Pro experience that explains its value without getting in your way.

Cleaner app structure:
* Reworked so the main destinations are easier to understand.
* Added Station Milestones 

Settings improvements:
* Added a clearer appearance preference with System, Light, and Dark choices.
* System appearance now clearly follows your iPhone setting.
* Updated App Status so it shows useful local record counts, storage status, backup status, update status, and Pro access.

Calculator improvements:
* RF line of sight inputs include units and support feet or meters.
* RF power inputs now use labels and support watts, dBm, and dBW.
* Converter lets you choose the input distance unit and focuses output on practical distance units.
* Map Distance supports stored locations without triggering navigation warnings.
* Calculator inputs now show clearer units where radio operators expect them.

Records and backup cleanup:
* Helpful checklist templates remain available.
* Import validation explains what needs review before replacing local data.
* Backup export remains free.

VHF/UHF should feel like a radio planning tool, not a settings console. The app is still local*first, still built for practical VHF and UHF work, and still careful about reminding you to verify legal limits, terrain, equipment ratings, RF safety, and local coordination before transmitting or installing equipment.
