QTH.app version 0.8.5 released

In amateur radio, the “QTHQ-code means “What is your position?” when used as a question or “My position is…” when used as a statement. The Automatic Packet Reporting System® is a common avenue that amateur radio operators communicate their positions, among other useful information.

QTH.app is an APRS® client application exclusively for the macOS platform. It connects to the APRS network  via radio or Internet to help operators receive, transmit, and visualize information being shared over APRS.

PRICING

QTH.app follows a “freemium” pricing model. QTH.app is free to receive APRS traffic. The transmit functions require a software license. This serves a couple purposes: It allows verification that the person transmitting holds a valid amateur radio callsign and it puts a few dollars in my pocket.

If you would like to purchase a license, please visit the store: QTH.app License
