Beech 18 Nav Lights

Anyone else experience this and know what’s going on? When turning on the nav lights, the COM 2 and ADF panel lights go out (as highlighted in screenshot). When turning off the nav lights, they come back on. Anyone know whats up?

I wasnt able to duplicate your issue. I wonder if it will continue after SU11. Are you using the PMS 530 mod or the stock gns 530?

i am using the stock 530 there. but after a little while the issue resolved itself. shrug
