Diskmonger, The M Resort is still on the same UHF DMR CC14 encrypted system you spent the time to analyze & map-out several years ago.
The Housekeeping & Maintenance TG on 451.8875 DMR CC9 repeater is a different high-profile system -- only takes about 20 min of listening & some junior detective-work on-line to figure out who it is, so I won't spoil the fun for people who like to challenge themselves a little.
