AGC comparison FW 4.48 vs 4.50 vs 4.51. My face is red

[Dave Hachadorian]

After I posted my glowing report on FW 4.50, I received an email
from N6XI suggesting that I should try reversing the two K3's
used in the comparison.  I tried that today, and was astonished
to see that the big differences I was seeing were in the radios,
and not the firmware.  It turned out to be two different pieces
of external hardware that were causing the big differences -
quite a fiasco on my part.

The bottom line is that I can't detect much difference in CW
performance of the three versions of the software.  The signal
dropout that was present in 4.50 has been fixed.

If there are differences in cw performance among the various
firmware versions, they are subtle.  I'm sorry for the
over-enthusiastic initial posting.

This is very interesting. Seems a hardware issue fixed in some versions.

What are the differences in the K3s that you are using?
