Ratings and Reviews
Several year user
Been using for five years for repeater maintainence. Quick and easy to use. An amazing range of tests and scales. I couldn’t work without it since I retired my slide rule. The battery wore out(!).
Specialized and useful
This app was exactly what I was looking for. Quick conversion between dB based units. Very useful. Creator very responsive to feedback and requests.
A very useful application.
I find this application to be very useful in my day-to-day work as an RF engineer it's really quite nice.
