I've been trying to figure out the METROPOLITAN ENTERTAINMENT CONVENTION AUTHORITY callsign WPYN377. According to my 436HP the system is a CAP color 10. I have for frequencies down as LCN 1 452.250, LCN 2 462.225, LCN 3 464.8125, LCN 4 464.9625 According to the FCC website, 452.850 is another frequency which I don't have programmed. I don't know the correct LCN for all of them because the LCN finder is not very useful on the 436HP. I can't pick up the system with my RTL-SDR / DSD+ from home because I live in Bellevue and too many tall buildings in downtown Omaha. I've picked up TGID's by sitting in my car parked along the riverfront. TGID 10 show office , 34 sounds like the Dock/Guard shack, 20 maybe housekeeping? 38 janitorial of food? 11 security? 12 maintenance? 28 security at gates, 29 Electricians? 22 Medical? also other TGID's 95, 23, 25, 13, 35, 19, 26, 15, 18, 42, 27, 41, 16. Can anyone else figure out the correct LCN?
