Hi Henk, PA3GUO

Compare please the quality of modulation only for 23 cm SSB
versus 2 meters and 70 cm SSB and not FM

You will note a big difference because the 23 cm on TS-2000X
is not linear

If you have no difference in SSB quality in your TS2000X probably
Kenwood already modified the bias voltage of the module M57762
in your transceiver.

By the way as far I know there are two possible simple mods to cure
the problem one is from VK4WS and the other one from RA3AQ
