v1.5.3 · Build 122 Official ARRL TQSL Engine Inside

TrustedQSL,
reborn for macOS.

Say goodbye to twenty-year-old wxWidgets dialogs and browser tab juggling. True QSL pairs the official ARRL tqsl cryptographic core with a native SwiftUI Operator Desk — uniting LoTW, QRZ.com, and Club Log signing, durable confirmation sync, live WSJT-X UDP capture, and a drop-in CLI bridge.

146 Tests Automated Verification Suite

Native macOS Application Interface

Built for clarity at the operating desk.

Inspect every workspace — from one-click multi-cloud signing and SQLite upload history to live DX Cluster spots and LoTW award progress.

Multi-Cloud Sign & Upload

Select Today’s QSOs, unuploaded contacts, or an ADIF file; verify station location and certificate validity; and sign for ARRL LoTW, QRZ.com, and Club Log.

ARRL TQSL v2.8.6 Core

Core Architecture

Every link between your rig and your confirmations.

Engineered to replace fragmented utilities with one cohesive, auditable macOS workflow.

01 · OFFICIAL CRYPTOGRAPHY

Review-First Multi-Cloud Signing

Embeds the official ARRL TQSL v2.8.6 engine alongside Apple Security.framework PKCS#12 import. Every ADIF contact is validated for station callsign, DXCC, UTC date coverage, and mode before signing to LoTW, QRZ.com, and Club Log.

02 · NEW IN v1.5.2 & v1.5.3

Visible Confirmation Sync & Replay

Independent LoTW and paged QRZ (250-record cursor) confirmation sync with live progress and cancellation. Replays matched confirmation evidence without overwriting local edits or tripping over legacy Unicode scalar-length fields.

Zero Metadata Conflicts
LoTW + QRZ Badges

03 · REAL-TIME INGESTION

UDP 2237 Listener & Log Watchers

Intercepts binary Log QSO (Type 5) and decode packets from WSJT-X and JTDX with zero disk lag, plus automatic file watchers for Lab599 Utility, SDR-Control (iCloud), and MacLoggerDX.

04 · DROP-IN CLI BRIDGE

`/opt/homebrew/bin/tqsl` Replacement

Point MacLoggerDX, RUMlogNG, WSJT-X, Cloudlog, N1MM, or Aether directly at True QSL. Enforces shared ADIF preflight validation and explicit station selection (-l) while returning standard exit codes.

05 · LIVE DX & AUTOMATION

Wait & Pounce + DX Cluster Telnet

Hunt needed DXCC entities and Maidenhead grids on FT8/FT4 with clear audio gap detection and a Halt-TX safety watchdog, or connect to global Telnet DX Clusters with instant ATNO highlighting.

06 · GEOGRAPHY & AWARDS

World Map, Awards & QRZ Rank

Plot contacts on a native MapKit 3D globe with geodesic great-circle paths, solar grayline, and live NOAA SFI/K-index telemetry — and track DXCC, WAS, Triple Play, VUCC, WAZ, and QRZ.com leaderboards.

Introduced in v1.5 · Operator Desk

Ten precision workflows for serious log hygiene.

From auditing your own LoTW server receipt inventory to previewed 1,000-contact bulk edits with guarded undo.

TQ-025 → TQ-034 Implemented

01 · LoTW Receipt Inventory

Compare local logs against your own ARRL LoTW report with separate queued, submitted, received, and QSL states.

02 · Aged QSL Follow-Up

Configurable worklist of unconfirmed contacts by age and receipt state; QRZ confirmation never masks missing LoTW.

03 · Paused Correction Queue

Field-by-field comparison and destination-specific review; never implicitly replaces or deletes remote QRZ records.

04 · Station & Date Profiles

Separate callsign, UTC date range, and Keychain namespaces with overlap prevention and combined read-only browsing.

05 · Certificate Reminders

Configurable UTC expiration thresholds, missing-key/pending alerts, historical coverage checks, and ARRL renewal guidance.

06 · Explicit Award Evidence

Track reported award credits and operator document references while keeping worked, QSL, and credit states distinct.

07 · Guarded Bulk Editor

Preview up to 1,000 contact edits with mandatory reason, durable checkpoint, atomic commit, and restart-safe undo.

08 · Scheduled .tqbackup

Opt-in versioned profile backups while open, with checksum verification and unfinished-upload quarantine on restore.

09 · AND / OR Smart Folders

Profile-owned saved queries across any retained ADIF field, with full Unicode and Gregorian UTC date precision.

10 · Per-Contact Audit Trail

Immutable submission snapshots, import decisions, edit checkpoints, and per-contact JSON history export.

Why Upgrade?

True QSL vs. Legacy TrustedQSL.

Same official ARRL cryptographic core underneath — generations ahead at the desk.

Capability	True QSL v1.5.3	Legacy ARRL TrustedQSL	Manual Browser Uploads
User interface & framework	Native Swift, SwiftUI & AppKit	Legacy C++ wxWidgets	Separate web portals
ARRL LoTW cryptographic engine	Official ARRL TQSL v2.8.6 embedded	Official ARRL TQSL v2.8.x	Requires external TQSL first
Multi-cloud upload queue	LoTW + QRZ.com + Club Log (durable)	LoTW only	Manual file upload per site
Pre-signing QSO inspector & editor	19,800+ QSO logbook + Import Review	Blind signing only	None prior to upload
Confirmation sync & evidence replay	Independent LoTW + paged QRZ merge	None	Manual ADIF download/import
Live WSJT-X / JTDX & Lab599 integration	UDP Port 2237 + Auto file watchers	None	None
Drop-in `/opt/homebrew/bin/tqsl` CLI	Included with preflight validation	Manual path setup	Not applicable

Engineering Transparency

Verified behavior & operating boundaries.

Documented test coverage and safety rules for your certificates and logbook.

146 Automated Tests Passing

Validated with swift test across 146 unit and regression suites — covering 10,000-contact inventory audits, Unicode scalar/byte ADIF boundaries, multi-page QRZ cursors, historical-fingerprint evidence replay, and guarded bulk-edit undo.

Read-Only Inventory & Paused Corrections

LoTW receipt checks and confirmation sync are strictly download/merge operations and never upload contacts or submit paid award applications. Correction jobs start paused; confirmed QRZ match-field changes require website review rather than implicit replacement.

Keychain Secrets & .tqbackup Archives

LoTW, QRZ, and Club Log credentials stay in macOS Keychain and are redacted from logs. Verified .tqbackup archives include private keys and are unencrypted so you can recover your station identity — store backup files securely.
