    Based on feedback from DXpedition users, Elecraft has significantly
    improved the K3's DSP AGC. The AGC threshold can now be set much
    higher, allowing more "headroom" for tightly-packed signals at similar
    amplitude.

    They've also eliminated the slightly "scalloped" (non-monotonic) AGC
    curve. The resulting AGC curve is very smooth, so signals right at the
    threshold can't be modulated by AGC onset.

    Early testers have reported excellent signal clarity in pile-up
    conditions. The new code (rev 4.50 or later) is expected to be
    released to beta next week.
