Finish 0.8.4
Need compare vs 0.7 versions from eddy555 or last hugen measure quality on ranges
Need update calibration after.
Changes:
- No auto power set for si5351 (power constant set to 3, you can change by command), compare noise level on < 300MHz (as i see should be better)
- Change band 3 generation settings (not drop generation in some range settings), check range 150-300MHz, 450+ MHz
- Optimize AIC3204 i2c data send (more faster)
- Allow si5351 low freq generation 800Hz - 10kHz (please not do all range calibration, made 10k-XXX or 800Hz - 100kHz)
PS As i see on freq > 900MHz noise from SPI bus or power made noise on measure (if try update display at this time - get big amount of noise)
