APRS app that keeps getting better

All apps have issues and bugs. This one seems to keep improving without causing big changes that would make users hate the change. Excellent program. I hope they continue on the same path of improvement and integration with new things like the new external bluetooth APRS devices on the market. -KX4MQ


Beacon Settings Needs to Be Better

At first glance, the app looks pretty good. Really liked it. After time and considerable usage, not so good. I started using app because radio beacons are unreliable in my area. I needed a more consistent result. This app is not it. The controls for beaconing is fixed set to a min beacon of every 5 minutes as the fasted rate you can get. Any faster is up to the app with no insight to how it chooses to beacon. It could be 30 seconds or it could be 5 minutes. I found it taking 4 to 5 minutes between beacons. At 40 MPH, this means the beacons are as far as 2 to 3 miles off. Not useful for me. I need last known position to be accurate to hundreds of feet while traveling. Not miles. I went back to radio where I control the beacon rate which makes sense for speed and accuracy.

Great, but I have one big issue

I love how easy this app is to use, but my big gripe is that I can’t use this app with vox on my radio. As soon as I launch the app, the radio just starts transmitting, and doesn’t stop. I have tried the PulseModem app, and it works great with vox, I don’t know what the difference is in how the apps handle the audio, but it would be great if something could be changed to make this work, because the layout of this app is easier to use in my opinion.
