Hello All, We have a two site Voted Simulcast consisting of 2 UHF Motorola Quantars, Thunderbolts, and 2 RTCM's. Master site is North, secondary Voter/TX site is West. Recently I have noticed significant choppy audio, mostly absent a PL, being transmitted from the West Site. It appears the repeater is keying/dekeying a couple times a second. On the West RTCM console I see: 02/27/2015 00:23:15.592 Inbound (Eth Rx) packet out of bounds by: -60 02/27/2015 00:23:25.532 Inbound (Eth Rx) packet out of bounds by: -60 02/27/2015 00:23:35.532 Inbound (Eth Rx) packet out of bounds by: -60 Physical link between the sites is over a Ubiquiti 5GHz link, then fiber. IPSEC end to end. Voter Ping output is below. PING (West): Packets tx: 100, rx: 100, oos: 0, Avg.: 13.940 ms PING (West): Worst: 22 ms, Best: 7 ms, 100.0% Packets successfully received (0.0% loss) Standard ping between Voter and West RTCM: 3297 packets transmitted, 3293 received, 0% packet loss, time 3297289ms rtt min/avg/max/mdev = 2.953/4.166/111.124/3.812 ms TX/RX buffers are 250ms. When I restart the West RTCM, the symptoms resolve for a hour or so, then begin to occur again. System was previously functioning normally. Only change has been from ADSL to fiber at the North site. West site was down for 2-3 weeks while the line was switched, so I can't absolutely correlate this issue to the connection change. Pings when the issue is occurring look good (<10ms voter to West RTCM) Any ideas? Thanks, Caleb
