The LimaSDR hardware is a project of DARC Ostverband Duisburg
The app is only a receiver with a range of 0.5 MHz to 20 MHz (a fixed divisor 8 of the hardware).
For easy tuning, there are three ranges: 80m, 40m and 20m that using scrollbars can be set.
Other frequencies may be entered.
The receiver has a agc and S-meter.
Through the menu the precise xtal frequency of the Si570 can be entered.
The determining of this xtal frequency can be done with the tool of PE0FKO
The hardware must be connected to the audio with a 4-ring plug and the USB through a USB host adapter.
When using this app on a phone the AGC portion falls to of the screen.
