Looking for power supply recommendations

George;

There are a lot of options. I have been very satisfied with the three MFJ 4230 power supplies I have, one for each rig. There is no discernible rf noise. I have run the Flex on battery while using the MFJ, and any noise is below the internal noise of the Flex. Mine is mounted beside the 6400 to keep the connections short. The connections are on the rear rather than the front for a clean looking installation. The front panel voltage adjustment allows the output to be adjusted to compensate for wiring losses,so that the the Flex sees the desired voltage during transmit.
