This is the All Purpose Voltage Booster specifically build to run a laptop
directly on your 12vdc system aboard. It is build to NOT make any interferences on your SSB radio
Designed and made by Sam Ulbing, N4UAU, ham radio
operator for our laptop
some years ago. We have since then a different system and thus have no use for this great voltage booster. It comes with the instructions on how to build it and it can be modified to accommodate different output voltages ... you could actually make it multi-voltages.
