Re: What do people do for building or sourcing custom inline fused power cables? #parts #power #supply #12v
Don't remove the powerpoles from that lead, add Powerpole connectors to your battery, and everything else that needs or uses low voltage power.? Pairs of connectors can be assembled handed and so

Re: QMX+ with 100 amp/hour lithium iron battery
The suggestion on adding a low value (100-1000 pF) capacitor in parallel with the 20-1000 uF bypass capacitors if the best answer. It has to do with the frequency response of the capacitors and their

Hi Bruce and other tone on the band friends, I have made no progress other than to speculate that replacing the 74CBT3251 'front end' chip might be an option.? Since the tones disappeared when IC402
