When using custom frequency, a spacing selector appears allowing
choice between 25 kHz (standard) and 8.33 kHz (European) channel
spacing. The frequency step adjusts accordingly.

Build and install RTL-SDR Blog fork drivers during setup to provide
proper support for RTL-SDR Blog V4 devices (R828D tuner). These
drivers are backward compatible with V3 and other RTL-SDR devices.
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Problems fixed:
1. Added start_new_session=True to dump1090 Popen - creates proper process
group for clean shutdown
2. Use os.killpg() to kill entire process group when stopping ADS-B -
ensures child processes are terminated and device is released
3. Track active device index in adsb_active_device for debugging
4. Add device info to /adsb/status endpoint
5. Add logging when starting/stopping ADS-B with device info
These changes ensure the RTL-SDR device is properly released when ADS-B
stops, allowing another process (e.g., airband) to use a different device.

Backend changes (routes/aprs.py):
- Remove -q h flag from direwolf to enable audio level output
- Add parse_audio_level() to extract levels from direwolf output

- Numeric level display (0-100)
- "BURST" indicator for levels >70
- Status text (weak/moderate/strong signal)

Major improvements to APRS decoding reliability:
Process piping fixes (prevent deadlocks):
- rtl_fm stderr -> DEVNULL (was blocking on unbuffered stderr)
- decoder stderr -> STDOUT (merged, single stream to read)
- decoder uses text=True, bufsize=1 for line-buffered reading
- Proper EOF detection in stream thread
rtl_fm command improvements:
- Use -M nfm (narrowband FM) for APRS
- Add -E dc (DC blocking filter) for cleaner audio
- Add -A fast (fast AGC) for packet bursts
- Sample rate 22050 Hz matches direwolf -r 22050
Parsing robustness:
- Strip direwolf bracket prefixes like "[0.4] " before parsing
- Handle multimon-ng "AFSK1200:" prefix
- Better error handling for early process exit
New /aprs/spectrum endpoint:
- Runs rtl_power to scan around APRS frequency
- Returns peak detection, noise floor, signal analysis
- Provides advice for antenna/signal debugging
- Supports region selection and custom frequency
Also added UK to region list (same freq as Europe: 144.800 MHz)

Direwolf requires a config file to run. Create a minimal receive-only
config at startup that configures stdin input with AFSK1200 modem.

Changed -q d to -q h flag. The -q d option was suppressing APRS packet
descriptions (the decoded output we need), while -q h only suppresses
the audio level heard line.
