[Elecraft] 4.48 vs 4.51 CW Decode

[W5RDW]

When I first installed 4.51, I had to fiddle around with a few adjustments
for the decode function to work as before, primarily adjusting THR lower. It
seemed 4.48 liked a THR of 7, but now 4.51 seems to like a THR of 3. I have
the AGC THC at 10 or so. Also, I always use the SPOT function to get the
received signal in the proper place to decode. 

It will decode any speed that I have encountered if the sending CW is
computer generated (it gobbles up the high speed W1AW code practice!) or the
CW Op has a very good fist. As the sending CW Op gets more sloppy, the
decode function starts to suffer, as I would imagine most decoders would do.
Some Ops do not leave a space between characters, so no wonder a decoder has
trouble. It loves the contests, where I imagine many are using a keyboard or
memory functions to send calls, exchanges, etc.
