Preferences

The Preferences page lets you customize Hamtrax to fit your operating style. From profile identity to subscription management, everything is accessible from a single place.

Accessing Preferences

1. Open Settings from the sidebar.
2. Navigate between tabs: Account, Preferences, and Plans.

Account

The Account tab contains your profile identity, security settings, and account actions.

Profile Identity

Setting	Description
Photo	Upload a profile photo (JPG, PNG, or WebP, max 5 MB).
Callsign	Your amateur radio callsign. Validated against QRZ/HamQTH on entry.
Name	Your display name as it appears across the app.
Username	A unique @username others can search for.

Plan

A summary of your current subscription plan. Founders see their founder number and lifetime status. Paid subscribers see their plan tier and renewal date. Free users see a prompt to view available plans.

Security

For email/password accounts, you can verify your email address, change your password, or change your email. OAuth users (Google, Apple) see a notice that credentials are managed by their provider.

Account Actions

Action	Description
Sign out	Sign out of your account on this device.
Delete account	Permanently delete your authentication profile. Contact logs and data are preserved.

Preferences

The Preferences tab contains four accordion sections: Station, Map, Activity, and Integrations.

Station

The Station section includes band plan, frequency display, and location settings.

Band Plan

Your default regulatory agency and license class determine frequency allocations and mode suggestions throughout the app.

Agency	Region
FCC -- United States	IARU Region 2
ISED / RAC -- Canada	IARU Region 2
IARU Region 1 -- Europe & Africa	IARU Region 1
ACMA -- Australia	IARU Region 3

These are auto-detected from your callsign during account setup, but you can change them at any time. Agencies that do not use tiered license classes show "Not applicable" for the license class field.

Frequency Display

Setting	Options
Display format	MHz (e.g., 14.201 MHz) or kHz (e.g., 14201.0 kHz)

Location

Hamtrax uses your location to find nearby parks and stations. You can control how your location is determined:

Mode	How It Works
Callsign	Location is derived from your callsign lookup (QRZ/HamQTH database).
Device	Uses your device's GPS for real-time location. Requires location permission.
Manual	You set coordinates, a grid square, or search by city. Optionally set an expiration (1, 4, 8, or 24 hours) or choose "Never Revert" to keep the manual location indefinitely.

Your grid square is calculated automatically from your coordinates, or you can enter it manually in Manual mode.

info

Callsign-based location is a good default if you operate from a fixed station. Switch to Device mode for portable or mobile operations.

Map

The Map section controls marker sizes and map overlays.

Marker Sizes

Each marker type can be set to Small, Medium, or Large:

Marker	Description
POTA markers	Parks on the Air park markers.
Contact markers	Markers for logged contacts.

Map Controls

Setting	Description
Show map scale	Display a live scale bar in map view.

Activity

Setting	Description
Spot visibility window	Slider (1--30 minutes). Spots older than this are hidden across Discover and the spots tools.
Auto-detect Park to Park	When logging contacts, automatically check Park to Park if the station is spotted at a park.
Suggest respot on frequency change	Show a respot checkbox in the QSO form when your frequency differs from your last spotted frequency.
Show activation edit warning	Display a warning dialog when editing contacts that belong to a POTA activation, reminding you to also update your log on pota.app. Enabled by default; disable to suppress the warning.

Integrations

The Integrations section lets you link external services for spot submission, contact sync, and contest logging. Each integration expands into its own configuration panel.

Service	Description
N1MM Logger+	Contest logging bridge. Requires configuration.
Logbook of The World	ARRL LoTW sync. Requires credentials.
QRZ Logbook	Bidirectional sync with QRZ.com. Requires credentials.
HamQTH Logbook	Real-time sync with HamQTH.com. Requires credentials.
POTA	Parks on the Air. No setup required -- works automatically via the public POTA API.

Each connector displays a status badge: Not Set Up, Credentials Saved, Verified, or Error.

Plans

The Plans tab shows your current subscription plan and allows you to manage your subscription.
