[Amps] KiloVac HC4 Relays

[Roger Parsons]

I have received a private email strongly disagreeing with my conclusions on these relays :-)

I still believe I am correct about the use of tungsten contacts in rf vacuum relays and that, based on manufacturers' information, the HC4 is suitable for use in an amateur linear. 

I should not have put the paragraph about gas filled relays into the message - although at least one of the manufacturers does indeed say that rf can ionise the gas, they are apparently commonly used in some high power rf systems.
