Most plugins that use reverse API to PATCH settings updates to remote server only do so when `useReverseAPI` is toggled, but not when the relevant settings are being updated. So lets fix the precondition to use the `m_useReverseAPI` flag instead. |

FunCube Dongle Pro+ input plugin
Introduction
This input sample source plugin gets its samples from a FunCube Dongle (FCD) Pro+ device.
Interface
The top and bottom bars of the device window are described here
1: Common stream parameters
1.1: Frequency
This is the center frequency of reception in kHz.
1.2: Start/Stop
Device start / stop button.
- Blue triangle icon: device is ready and can be started
- Green square icon: device is running and can be stopped
- Magenta (or pink) square icon: an error occurred. In the case the device was accidentally disconnected you may click on the icon, plug back in and start again.
1.4: Stream sample rate
Baseband I/Q sample rate in kS/s. This is the device sample rate (4) divided by the decimation factor (6).
2: Local Oscillator correction
This is the correction to be applied to the local oscillator in ppm.
3: Auto correction options
These buttons control the local DSP auto correction options:
- DC: auto remove DC component
- IQ: auto make I/Q balance. The DC correction must be enabled for this to be effective.
4: Decimated bandpass center frequency position relative to the FCD Pro+ center frequency
- Cen: the decimation operation takes place around the FCD Pro+ center frequency Fs
- Inf: the decimation operation takes place around Fs - Fc.
- Sup: the decimation operation takes place around Fs + Fc.
With SR as the sample rate before decimation Fc is calculated as:
- if decimation n is 4 or lower: Fc = SR/2^(log2(n)-1). The device center frequency is on the side of the baseband. You need a RF filter bandwidth at least twice the baseband.
- if decimation n is 8 or higher: Fc = SR/n. The device center frequency is half the baseband away from the side of the baseband. You need a RF filter bandwidth at least 3 times the baseband.
5: Decimation factor
The I/Q stream from the FCD Pro+ ADC is downsampled by a power of two before being sent to the passband. Possible values are increasing powers of two: 1 (no decimation), 2, 4, 8, 16.
6: Transverter mode open dialog
This button opens a dialog to set the transverter mode frequency translation options. The details about this dialog can be found here
7: LNA toggle
This checkbox is used to toggle the LNA on/off
8: Mix toggle
This checkbox is used to toggle mixer amplifier on/off
9: Bias tee
Use this checkbox to activate the bias tee.
10: If gain
Use this slider to adjust the gain of the IF amplifier.
10: RF filter
This controls the tuner filter (band) used:
11: IF filter
Selects the IF filter bandwidth
