In a few weeks' time (with a following wind) my QDX digital transceiver should arrive. With a 12v supply, there is a danger of the PA being badly over-rated and failing. Most of my gear runs from a 13.8V, so it would be prudent to run the QDX from a lower supply voltage.
My easiest solution is a string of suitably rated diodes in the supply. I have 10 off 3A silicon diodes that should be here next week. I could drop 6V with these if I want, making the QDX run safely from 9.8V.
I'm considering using a "buck converter" with my QDX. Something like:

and I wondered what you think of this technique?

Hi Mike - my main concern is noise. This can be an issue. Although I may have missed it, what current can it deliver? Mine is a linear PSU so no noise!!
