I don't think it's nearly fast enough for QSK. What kind of rig
are you using? On my FT-1000D, I brought out the receiver input
to RCA jacks on the back panel so I could insert my MFJ-1025
after the rig TR switching. Many rigs that are designed for use
with a transverter allow the RX line to be broken (TS-940 for
instance) for insertion of items such as the MFJ.
