The meter lamps on my Omni VI dim noticeably when either the VOX or SPLIT LEDS are lighted. It is doubtful that this is due to a power supply lead voltage dropping from the increased load of the LEDs, for two reasons. The amount of current the LEDs use is probabaly less than 20 mA each, and the controlled voltage source for the meter lamps is on a completely different board, the Low Level Driver Board. So the amplitude or duty cycle of the "digit driving pulses" coming from the LED Display Drive Board must be changing when the SPLIT or VOX LEDs are turned on. This doesn't seem right.

Anyone else with an Omni VI notice this, or know what the cause is?
