It's a capacitor that the Astron designer left out as a cost cutting measure. Go to the Astron page at repeater-builder, then to the introductory article. It's all explained there. >BTW: >I've never been able to find a good clear copy of the astron schematic. They >are always "fuzzy" whae you blow them up where you can print it off. We offer for download what we are given. Some schematics are better than others. A lot of folks don't know that the scanning programs that offer "compression" on JPGs do it by throwing away detail. ZIPping the file shrinks it for emailing without loss of detail. We'd rather have the large file ZIPped and emailed to us and let us shrink it as we make a PDF out of it. >William Brown >KG4AQH Mike WA6ILQ
