The N7IBC UHF/70cm repeater is a low level open repeater, located at McCall, Idaho (e.g. 100 miles due north of Boise) and can be linked to the KC7MCC CIARC repeater via the 33cm Link Backbone under DTMF command by a control-operator. The N7IBC repeater provides coverage along the highway 55 cooridor, from Little Donner to north of McCall, and into portions of Adams County.

Why Hytera Was Chosen: A number of people have asked why Hytera was chosen over Motorola. Since Motorola customer programming software is a subscription service, there would be an on-going charge simply to be able to maintain programming of the repeater. No such subscription charge exists with Hytera. Pirating software is not an option, legally or ethically. Motorola may very well be a viable choice for other repeater owners / operators if the subscription fee is not objectionable to them, or if they have a business relationship with Motorola that negates the cost of the subscription. Given a very balanced comparison of Motorola and Hytera repeater specifications, and Hytera's more favorable retail pricing when compared to Motorola, Hytera simply made the most economic sense.
For those wishing to add the N7IBC UHF/70cm DMR Repeater to their DMR code-plug, the following programming parameters should be employed:

If you are constructing a code-plug that supports the KC7MCC, N7IBC and W7CIA DMR repeaters, it is recommended interleaving channels for each of the repeaters as contiguous channels of a like talk-group to promote driving safety. For example, if the TS1 NET for the KC7MCC DMR repeater is adjacent to the channel for the N7IBC DMR repeater, and then the W7CIA DMR repeater, you will not need to change zones when mobile operation requires you to move from one repeater to the next. You will only need to change channels.
Dynamic talk-groups (i.e. push-to-talk talk-groups), residing on time-slot 1, are available to stations directly using the N7IBC DMR repeater with DMR Tier II equipment, or by stations using analog repeaters that are on the CIARC 33cm link back-bone (when enabled). While stations on DMR will have the ability to activate a specfic dynamic talk-group, users from the CIARC link back-bone do not have the ability to select a talk-group and can only use the talk-group that is currently activated.
Calls initiated from other repeaters that are on the BrandMeister network, and appearing as a dynamic talk-group on time-slot 1, will be heard on the CIARC repeater network whenever the 33cm link is enabled. Any traffic on the CIARC repeater network will be heard on the active dynamic talk-group on time-slot 1. This means that your traffic may be heard on other repeaters in Idaho (and other regions, states, countries). The 33cm link will be disabled during the monthly CIARC NET, and at other times at the discretion of the control operator(s).
The N7IBC repeater is programmed to give repeat audio priority over external PTT (i.e. 33cm link) audio.
The KC7MCC 70cm/UHF DMR Repeater, N7IBC 70cm/UHF DMR Repeater and W7CIA 2m/VHF DMR Repeater are configured to subscribe to a cluster on Time-Slot 1 / Talk-Group 8 and to another cluster on Time-Slot 2 / Talk-Group 2. Respectively, these channels are named TS1 NET and TS2 NET. Any communications occurring on any of these repeaters will be heard on that repeater and the other two repeaters when one of these channels is used. Clustered Talk-Groups are STATIC.
The maintaining of a static talk-group on both time-slots is not conventional. The purpose of doing so is to support primary NET operations on one time-slot, and allowing traffic to be moved off of the primary NET and onto the secondary NET in order to maintain communications capability while allowing the primary NET to serve, unimpeded by traffic, as a coordinating NET. The convention that has been established for these two clustered time-slot/talk-group pairs is that the primary NET operations will be conducted on TS2 NET while off NET traffic will be handled on TS1 NET.
A composite coverage prediction for repeaters included in these clustered channels is shown below:
Because GPS / APRS data requires the use of a time-slot, and have the potential to cause interference to other users (including the potential to subscribe to a different dynamic talk-group), users should disable automatic GPS data beaconing (i.e. beaconing based on time intervals or distance intervals). Transmission of GPS data associated with either Push-To-Talk (PTT) activity or manually transmitting GPS data are allowed as this occurs under the control of the operator and will not present a risk of interference to other operators.
The RESET event table contains no data for the N7IBC (311603) DMR Repeater. This is indicative that the IP reset module has not yet been installed on the N7IBC (311603) DMR Repeater.
If you are researching the Hytera RD-982 repeater and are looking for additional technical information, including guidance on configuring the RD-982 to participate on the BrandMeister network, please see the W7CIA VHF DMR Repeater page.
