[MAMS] relay driver

[Zack Widup]

Hi Danny,

How does it latch? I have a HP33311C relay in my 24 GHz transverter. It is
configured by supplying 24 volts to one pin and grounding one of two other
pins. When one pin is grounded, it latches one way and then when the other
pin is grounded it latches the other way. You just have to make sure you
unground the one pin before grounding the other pin. Easy to make it work,
as all I have to do is use another smaller relay to switch it back and
forth between transmit and receive. My transverter for that band is full of
relays anyway and I had a spare set of double-throw contacts available on
one.
