SSBs wreak havoc with all sorts of electronics
because of the wattage involved, stray currents, and broadcasting on broader frequencies because of bad connections. If you're going to install a choke, start with one on the power supply to the SSB
as that is the primary culprit. Adding chokes to the power supplies of equipment
that is going bonkers when you transmit is also a good idea. I know of people who can't transmit on SSB
when they're using their autopilot
(or vice versa) because the AP will go haywire.
Do you get a "brown out" on the rest of the DC system, with your lights dimming, when you transmit on your SSB? One possibility is that your monitor detects the drop in voltage during transmit and thinks it's being shut off or goes into power saving mode or sleep.
Make sure that all the SSB connections, such as between the tuner and the antenna
, are clean and secure. Also, try and run any other critical wiring
as far from the SSB wiring
as you can. Lastly, dial down your transmit power from 150 watts to 50-75. It won't make much difference to the reception
of your signal unless you're trying to reach out thousands of miles.
