I don't think you will get much more noise as the DC/DC converter is only supplying power to the Power amplifier.
I did not use it myself as I am not finished with the other tweaks I want to implement.
If it will not work for me is not a big issue as I plan to stay QRP only.
I might try something later today, or tomorrow, using the same converter I have posted above. Set he converter at 13V and use a 3Ah LiPO pack that is built with 3 cells, so when fully charged only has 12.2V.
If it works I'll let the group know.
