QTH COMPASS GOOD FOR DIRECTIONAL ANTENNAS

The QTH COMPASS app is a must have app for radio operators who use directional antennas like yagi’s or biquad antennas. The altitude and distance features are an added plus when calculating location height and compass direction. After switching from android to iOS, this is my number one go to app for finding location direction and height and I use it daily.

Cannot re enter remote wrap

Hi. When first using app, I could enter a remote QRA and app gave compass heading and distance ok, but I could not see how to enter a different remote locator. It was just off the edge of my iPhone screen! Not immediately apparent. App needs a tweak?

Response from developer

Hi! Thanks for bringing that up. I‘d like to fix that asap. Which iPhone and iOS version are you using? I“d also appreciate you sending a screenshot to appledev@dellwig.de.

Awesome direction and distance tool

Not just to show your own gridsquare, but any other when you tap on a map or put in their maidenhead grid square. Then you get a compass guide to aim your antenna. Simple and well thought out app.

Nice and helpful app

Really enjoy this app. Great addition to my ham radio apps to get location bearings for beam adjustments. One suggestion would be the ability to select units for altitude reading. In the US we typically use feet instead of meters.

Response from developer

Thank you! You are right about localized measurements. I will change that in version 1.2.1, which will be release very soon!
