Both the ANC-4 and the MFJ-1026 have provision for an external input
to handle the TR switching. If your rig provides a switched ground
output, it can be used to the switch the noise canceller in and out
of the line faster than waiting for the internal rf detector to do
the job.
My K2 provides the TR switchg output a few milliseconds before rf
starts coming out the spout, so gives my MFJ-1026 time to switch.
Good luck and 73

Subject: Topband: MFJ-1026 noise canceller
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.
