Scheduled Static: Timeslot 1: 31513, Friday, 2130 – Saturday, 0100 in support of the Nightowl DMR Net. 31515 will T RF over the air during this time period to encourage participation in this net and advance DMR proficiencies and skills.

Program your radio codeplugs to utilize the slots listed for these Talkgroups to avoid the repeater TXing on both TS 1 and TS 2, one Static and one Dynamic for the same TG. This maximizes availability and exploits the advantages of 2 timeslots and DMR’s Time Division Multiplexing (TDMA) capabilities!

Please use Timeslot 2 for Dynamic calls (any IDs not listed as Static)

This maintains Slot 1 available for its Static TGs and avoids interrupting QSOs.

Any other BrandMeister Talk Groups accessed on either Time Slot 1 or 2 are DYNAMIC with an inactivity timeout of 15 minutes after which the slot will revert back to its Static programming. Time Slots are only applicable to local RF access and must be considered when designing your Code Plug for W4HPT Repeater operations.

If you program your radio for analog FM operations on the W4HPT Repeater, you will need a 100.0 tone included. CTCSS tones do not apply to DMR operations. Generally, the repeater is not used in analog FM mode but maintains this capability in the event DMR capabilities are lost.
