N.L. = Noise Limited
dBpep = dB below PEP output power.
 
Notes:
  1) When receiver values were given for preamp on/off, the preamp on
numbers were used here. (or IPO/AIP off)
 
  2) When values for more than one MF/HF Amateur band are given, the
worst numbers were used.  (example:  general coverage receiver numbers
for 1.0 MHz were not considered, if a rig covers 50MHz, those numbers
were not considered.)
 
  3) Dynamic Range and 3rd order intercept numbers for the TS-450S and
TS-690S do not indicate performance as bad as such numbers would
usually warrant.  Although 3rd order products appeared at the MDS
level at a fairly low level, they did not increase in amplitude with
rising input signal level as rapidly as one would normally expect.
See the QST review for more details.
