[Elecraft] XV144 and linear amplifier

[Don Wilhelm]

Samir,

The only valid reason I know of to use a sequencer is to protect 
preamplifiers and other devices that could be damaged by the onset of 
RF.  Another common reason is to allow time for a slow amplifier relay 
to switch so you do not cause arcing at the amplifier contacts - I do 
not consider that a valid reason becuase the real solution is to replace 
the map relay with a faster one.

So, you may not need a sequencer, but consider the amplifier relay speed 
in making your decision.

73,
