Exactly what I was looking for

This app is exactly what I need: to be able to do wspr beacon antenna testing using my phone and portable rig. Easy set up and operation. I run it and hold the rig mic up to the phone. Nice product.

Works well but ...

This app works well on iPad mini but could use a few improvements.

1. Draw map using short paths. For example, QSO from my QTH in Arizona to Japan shows long path through Europe.

2. Provide a way to set the length of history time for showing reports.

Great support

I have even very pleased with this app driving my KX3. It is very easy to set up when you want to make a quick WSPR test. I had a question regarding one of the setup parameters and received a quick email response with a clear explanation.

Good software, thanks!
