The DX Connection QSK-2500 switch has provision for adjusting the
various delays and can handle a wide range of transceivers and
amplifiers. When correctly configured, it will not hot switch when
keyed, protecting the life of the relays. It was reviewed in the
September 2016 issue of QST.

Of course. beginning with the K2, all Elecraft rigs have a delay
built in -- that is, TX begins 8 msec or more after the amp control
line is keyed. On the K3 and later relays, the delay is adjustable. 8
msec is enough for most amps with GOOD relays (vacuum relays), but
not enough for slower relays. Every rig I've used since getting back
on the air in 2003 had that delay built in. Those rigs included
TS850, Omni V, and FT1000MP.

The "secrete" to running QSK with an amplifier is proper sequencing
of whatever keying is used...relays or PINs.
