How do you control the sweep? My control changes seem to have no effect.
Okay, I kept at it. Seems like the sweep controls have to be set a few times before they take effect.
Also, I suggest a “Sweep” button next to the preset buttons. I really don’t get the concept behind the way that sweep works, currently.
This is very nice. Wish I had this oscillator when I was troubleshooting ground to air radios; 1KHz tone :)
Hi José,
Thanks for the comment. I’m the designer behind the app. Would you mind explaining what “troubleshooting ground to air radios” is? Thanks!!

Hello Brian,
I’m a communications maintainer in the military. One of the pieces of equipment I used to work on were the radios used by air traffic controllers to communicate with airplanes.
One of the preventive maintenance test you do to the radios is verifying the receiver section of the radio and a 1KHz tone at 30% modulation is used as a test tone.
I’m sure I would have found a way to use your app if test equipment was not available.
Thanks for the reply!
