Two possibilities come to mind immediately: 1) connector problem on control box 2) relay problem in the control box. You didn't mention if the problem tracked the control box preamp being on. If it does then the preamp transistor may have been damaged. The schematic is available at http://www.aytechnologies.com/TechData/FilterPreamp_160-80.pdf . 73 Gary, N7IR _______________________________________________ UR RST IS ... ... ..9 QSB QSB - hw? BK |
