N4GN:" . . .comparing these three waveforms, I would expect the Field to be 
much improved over both the original MP and the Mark-V.  In other words, it 
looks to me like Yaesu has tried to address this issue in the latest 
version, and the Field could be expected at least to have LESS of a key 
click problem than the two earlier versions.  Maybe they even SOLVED the key 
click problem with the Field."

Recently, ARRL started including keying sideband plots in their expanded 
test results.  It is interesting to compare the Mark-V Field (p15 of 
http://www.arrl.org/members-only/prodrev/pdf/lab/mark-v-field.pdf) with the 
756Pro2 (p13 of 
http://www.arrl.org/members-only/prodrev/pdf/lab/IC756pro2.pdf).  The Icom 
is down nearly 60dB at +/- 1Khz and the Yaesu is only down 35dB at +/- 1 
1khz, even with its improvements over the original MP.
