7月26日的VHF / UHF Radio Field Planner应用程序分析

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.

Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ 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.
