I have ever used has a Stby setting. It would make absolutely no sense not to have one. It can take three minutes on some radars for it to warm up so you can Tx. If you need your radar
fast and it is completely off...well then, your going to have to wait. So consider the downside of putting in a separate breaker for the magnetrons heating
element on the radar....you may just need to get a relative motion line in a hurry as you see the lights of that 26 knot
containership coming over the horizon.
