They will certainly arc if the operator is improperly loaded <G>.
However if the amplifier is underloaded, voltage in the output
"tank" will increase. The "limit" for underloading is operating
into an open circuit (T/R relay not closed, etc.). If the bandswitch
is operating close to the limit already (as is the case in some
amplifiers), overdriving an underloaded amplifier can damage the
bandswitch.

Oh, do you mean to say that bandswitches could arc due to improper loading
by the operator? Lou
