? The HC-1 or RJ-1A will switch in under 2mS when used with a speed-up
circuit. This is fast enough to not hotswitch with even a 5mS
transceiver. The K41 series relays are slower.
- Note - the speed-up circuit I use requires 100 - 150 volts DC. For
those amplifiers that do not have a built-in 110vdc relay supply, it is a
simple matter to add a 150vdc supply with one inrush limiter, one diode,
and one filter-C. See Figure 7 on my Web site for details.
