What it does¶
A small control panel for the FUNcube Dongle Pro and Pro+: it sets the tuning frequency, the LNA and mixer gains, the filter selections and the IQ correction, all of which the dongle exposes over USB HID rather than through its audio interface.
Why you would want it¶
The FUNcube presents itself as a sound card, so audio software can read its samples but has no way to tune it. This is the other half. Without something like it the dongle sits wherever it was last set.
Before it will work¶
A FUNcube Dongle, and permission to open its HID device -- a udev rule, since HID access is not granted to ordinary users by default.
How it installs¶
- apt:
qthid-fcd-controller
Known problems¶
Pro and Pro+ have different frequency coverage and different gain controls, and a control that does nothing usually means the wrong model assumption rather than a fault. This catalog also carries gr-funcube for the GNU Radio path; the two do not conflict but only one should be holding the device at a time.
Keeping it current¶
- probe: apt policy
- strategy: apt_upgrade
