I have two scanners that receive a number of SA LTR sites just fine. However, Airwaves Northeast (Queens Crown) is listed as LTR in the database and I have confirmed the LCN and frequency entries. However, neither scanner ever stops on any transmissions. I know there is activity on at least one frequency (464.975 in this case) as I can hear clear audio listening on SDR# or just holding my scanner on the physical frequency in the list for that site. I tried using the SDS100 LCN finder and it sees activity on that frequency (as evidenced by an RSSI) but it doesn't show an LCN's found. The The audio is strong and clear and I am hearing voice conversations every few seconds. Any ideas? Last update on RR was 2018...could they have changed to a system I can't monitor?
