| The availability of reasonably high-power microwave amplifiers has made
switching in transverters more troublesome. At milliwatt power levels
sequenced switching was not essential, and even at powers up to one watt,
many operators get by without any sequencing. However, at higher power
levels, like the 40-watt amplifiers for 3456 MHz which recently became
available as surplus, the possibility of damaging a coaxial relay by “hotswitching”
(with RF power applied) becomes significant. Even at 10 GHz,
with amplifier outputs of 3 watts and more becoming common, we are
pushing the hot-switch (switching with RF power already applied) capability
of small SMA relays. The DB6NT1 10 GHz transverter MK2 instructions
state: “Urgently the use of a sequence controlers is recommended.”
New Version Option: Output Power LED
