The September 11, 2019, at 18:30 hrs. The location will be the Trinity County Office of Education conference room, 201 Memorial, Weaverville, CA. We are going to test a new frequency for the Hayfork Bally (146.73 MHz) repeater, as we have been having ongoing interference from the Chico repeater. For this activity we will be tuning the 146.88 MHZ repeater’s duplexer. Then we can use that duplexer on the Hayfork Bally repeater to test a new frequency.
