Not sure what qst .. I think 1983 they tested the FT-102. I will have to dig out all my old issues. Their are other rigs that have low IMD ...the Kenwood TS-930 , 940, 950SDX... FT-1000D , FT-767 , 1000MPmk5 they all had high voltage finals (28v) or higher...Just about any solid state radio with high voltage finals had no problems getting down to the -35 mark or better...... 73's John
