[Elecraft] Vacuum Relays and 30 WPM QSK

[Jim Brown]

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.
