Some users note a faint "hiss" or "chuffing" artifact when tuning through frequencies, caused by the Si4735's aggressive internal digital muting during tuning steps.
Retained the same main PCB date but updated the display board and changed the audio amplification. Some units in this era introduced a slight "hiss" at zero volume.
