Where Does DDUtil (3.0) get supply voltage info

DDUtil generally shows 13,8V on the Flex 6300 as it should. During TX (PSK31 for example) the voltage drops to a range of 12.6 and sometimes as low as 11.8.

I have a 32 Amp switching power supply with nothing else running so I am wondering why the drop under load? Is it because the 6300 DDUtil is sampling at too slow or fast rate?

The radio's internal voltage is streamed in a collection of meters sent from the radio many times a second over the VITA-49 protocol.  These meters are made available as part of the FlexLib .NET interface (part of the SmartSDR API) on various objects.  For example, all meters related to a lice receiver are on that slice object.
