[Elecraft] MCU 4.51

[Arie Kleingeld PA3A]

Took the FW4.51 for a spin at PI4D in the CQ-M on 20m in SSB and CW 
yesterday afternoon.

AGC THR on 12, SLP on 10.

Smooth operation, NB performed OK for the key clicks from a nearby freq.
(NB is DSP 2-3 and IF MED3)

Was it better than FW4.48? Not sure, but I like it that the threshold 
can be moved upward a bit, it was always on 8 before.
I did not encounter big pile-ups.
When I had two stations of the same strength on exact the same freq it 
was still hard copy to pick only one out.
