10Ghz transceiver...PTT and coax relay control

Getting closer to taking this transverter out for a field test. Today I wired up a relay driver for the latching SMA coax relay I'm using. I based it off of this design: https://3fs.net.au/microwave/latching... There's a 12v relay I'm using to switch between TX and RX. When not engaged, it sends 12v to the RX side of the relay driver. When the PTT is depressed, the sequencer will engage the 12v relay, which then sends 12v to the TX side of the relay driver. The Mk5 W1GHZ sequencer I'm using also has a "Safe" mode which detects RF and immediately sends all RF to attenuator / ground to protect the circuitry. Once PTT is received later, the TX side of the coax relay is energized, we wait a small delay then allow the RF to continue on to transverter
