Conventional Part 90 UHF business repeater system, 12.5 kHz narrowband FM. - text: | AUTHORIZATION STATUS: FCC ULS shows WNKX791 EXPIRED 2024-06-22 and CANCELLED 2024-08-24 (granted 2014-04-11, service code IG, eligibility rule 90.35). No successor Chicago Botanic Garden license was found in the 2026-09-26 l_LMpriv or l_LMcomm dumps. The system is still listed as active in RadioReference, so the hardware is presumed on the air under a renewal or relicense not yet reflected in the bulk data. Frequencies are retained here as monitoring reference, not as evidence of current authorization. - text: | SOURCE CORRECTION 1: the RadioReference free-text header gives the call sign as WNKY791. That call sign returns zero records in FCC ULS. The tabular listing's WNKX791 is correct and is used throughout this file. - text: | SOURCE CORRECTION 2: RadioReference lists the input for 464.1000 (CBG Garden 7) as 468.1000, a non-standard +4.0 MHz split. FCC ULS shows 464.1000 paired with 469.1000 on WNKX791, and 468.1000 does not appear anywhere on the license. This file uses 469.1000 (+5.0 MHz). - text: | 464.0625/469.0625 and 464.5250/469.5250 are authorized on WNKX791 but carry no published tone or usage. 464.5250/469.5250 appears in the FCC license only - it is not in the RadioReference listing. - text: | 457.1125, 457.2875, 457.4125, 457.6875 and 457.8625 are low-power mobile/on-site itinerant frequencies on the license. RadioReference notes NFM/NXDN operation on these; no NXDN RAN has been observed, so mode is left as FM with a note. - text: | DPL codes come from RadioReference and are published as a single code per channel; they are recorded as matching TX/RX DCS with normal polarity, which is the usual Part 90 configuration but has not been independently verified off-air. organizations: - id: org_chicago_botanic_garden name: "Chicago Botanic Garden" locations: - id: loc_cbg_glencoe name: "Chicago Botanic Garden, 1000 Lake Cook Rd, Glencoe, IL" lat: 42.145306 lon: -87.783667 stations: - id: stn_cbg_wnkx791 call_sign: "WNKX791" organization_id: org_chicago_botanic_garden location_id: loc_cbg_glencoe service: "business_itinerant_part90" antennas: - id: ant_cbg_wnkx791 station_id: stn_cbg_wnkx791 name: "Chicago Botanic Garden base antenna" height_agl_m: 13.7 authorizations: - id: auth_fcc_wnkx791 authority: "FCC" service: "business_itinerant_part90" class: "IG" identifier: "WNKX791" notes: "Industrial/Business Pool, conventional.
