DC-DC CONVERTER BOX
thingiverse
A simple box with vented lid to convert 10-40V to 7.4V for hanheld V/U radios. I made it as a supplement to https://www.thingiverse.com/thing:5326830. The choosed DC-DC converter https://grobotronics.com/dc-dc-step-down-1.3-35v-3a.html seems noiseless on VHF and UHF bands and keeps the demanded by FT-4X load well enough.
