I too still suffer from the notorious "pop" when powering on. I would
be interested if this change may help.
The "AF noise burst" that is eliminated by the latest firmware was
caused by the AGC being turned off until about 2 seconds after power-up.
If you had been tuned to a strong station, with the old firmware, you
could hear a couple of seconds of very loud audio. That no longer happens.
The "pop" heard in the speaker when turning on is an inherent property
of the speaker amplifier IC, and cannot be changed in firmware. If we
come up with a way to minimize this, we'll let you know. Meanwhile, you
could plug in your headphones just when turning on power; this cuts off
the speaker amp.
FWIW, the "pop" doesn't bother me at all... the "burst" was extremely
loud, even with no signal, on a noisy band. I'm quite happy with the
fix.
Thanks!
