I was over and removed the 900 receiver preamp today. This looks like it made some difference for the better on the 927.050 repeater, as I'm able to key it up from my house now. About 7pm we had a network outage, and it was on the service provider side. Tyler, KM4RAE worked on it and got it going by about 12am. I'd like to thank him for his help on this! 73's -- Bryan Fields, W9CR Florida Simulcast Group, Inc.
