I have been fighting bad band noise on all of my sBitx's from the DE to my V2 and V3, finally decided and set out to find another solution. I researched the most quite Buck converter that the RC and

Bob, I do have a noise floor on 40 meters, but by other radios are not affected the same as the BitX40. I would like to take the radio out of the shack and operate somewhere portable. unfortunately
