Any opinions on the MFJ-1026 noise canceller?  Fast enough TR switching for
QSK?  TR switching relay noise?

I tried a JPS ANC-04 and didn't like it, primarily due to the fixed (via
resistor) TR delay time.

Thanks.

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.
