The BRATS are working hard to maintain and improve the WB3DZO linked repeater system. As a part of this process, we've installed new radios and filters at several of our sites.
One of the features we're looking into is whether a PL tone will help cut down on activations. For now, we've only enabled it on one of our receive sites, so no PL is necessary to reach the repeater from most of Baltimore, but we encourage you to set PL 156.7 to ensure you can hit every receive site.
Although we hope the summer storm season is quiet, we're working hard to make sure our gear is ready!
