What It Won’t Do
- Collect data from weather stations. Check out WeeWX for this.
- Act as a dedicated IGate or Digipeater. Better solutions exist for this.
At the moment, QTH is in beta testing, and is only available to volunteers in the beta test program. Please email me at email@example.com if you are interested in helping out as a beta tester.
Once released, I will be going with a “freemium” pricing model. QTH will be free to receive APRS traffic. The transmit functions will 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. My current thinking is that the price will be somewhere around the $30 mark.
