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 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.
