Hi all... I've been reading on this forum that there have been some issues with the bluish capacitors for the QCX low pass filters.? I recall that the matter is on Hans' list to investigate, but haven't seen an announcement from him about his conclusions yet.? I ordered an LCR meter (marked LCR-T5, has a red PCB with lever socket and buttons marked OFF and TEST) on ebay to check mine.? I'm now building my QCX (20m version).? The nominally 390 pF capacitors C25 and C26 measure at 368 and 370 pF.? The nominally 180 pF capacitors C27 and C28 measure at 164 and 172 pF.? The meter doesn't show them as being particularly lossy.? I don't know the claimed tolerance for these capacitors, so I don't know if being off by 5-9% is significant, nor do I know whether this inexpensive LCR meter is capable of measuring to 5% accuracy. Is this enough information to decide whether to order alternates?
