The Rochester LTR-Net site is deprecated. The CC is gone but one LCN is still on the air with idle pulses and broadcasting "Site=0".
Avon LTR CC is still active with voice channels shared on demand with NXDN. The Macedon and Hopewell LTR-Net sites are still active.
My reception of Avon is intermittent due to co-channel Newark NXDN.
