12V refrigeration
Radio Frequency Interference (RFI) Is not an Adler Barbour
refrigeration problem as Larry indicates it is a boat refrigeration industry problem. It seems that only a very few boaters are concerned with RFI, the others are willing to set the VHF squelch high enough to silence it out. A few system manufacturers have received complaints from ham operators about RF from their refrigerators or other boat's refrigerator's parked nearby. On the few boats that are experiencing a problem the full box copper screen over the condensing unit does seem to satisfy at least three radio operators that answered my resent survey.

Alder Barbour and others make them. David AAAAACCCCCKKKKKK!!!! ADLER BARBOUR!! If you install an Adler-Barbour electronic 12V compressor, be SURE you put it into an RF shielded screen room! We had one on "Claire's Navie" that had this AWFUL pulsing RF noise ON VHF CHANNEL 16!.... Bzzt....Bzzt.....Bzzt,Bzzt,Bzzt.....Bzzt......Bzzt .......Bzzt, Bzzt, Bzzt....repeating the exact sequence of SQUELCH OPENINGS on both VHF radios for your entire watch! Drove us crazy until I turned the damned thing OFF~! Only bothered Channel 16...of all the channels....JUST 16. Larry |
