Introduction

The K1BMW UHF/70cm repeater is a low level open repeater, located at Truckee, CA. The K1BMW repeater provides coverage along the highway 89, 10-miles north and south of the Prosser Lake area and may be reachable with a mobile radio in the Reno area.


TIP: If you are unfamiliar with DMR, please see the DMR PRIMER page for an introduction to DMR and references to additional DMR introductory information.


It is absolutely essential that all operators become familiar with the DMR operating guidelines. These can be found on the Idaho ARES web-site by clicking here. These guidelines provide a context regarding the shared resource nature of DMR and wide-area networked repeater operation, and are structured to make the operating experience more enjoyable for all operators.

Operators who do not comply with the above mentioned guidelines may find themselves subject to FCC part 97.205(e) restrictions.


Operators hearing stations that do not adhere to the DMR operating guidelines are encouraged to not respond to operators that operate in violation of the guidelines in an effort to discourage poor operating practices.

Any operator using any Transmit Admittance other than Color Code Free will be requested to change their code plug to Color Code Free before conducting further operation on the repeater. Any station operator refusing to use Color Code Free will result in the exercise of 97.205(e) to exclude that station from operation on the repeater, and any susbequent operation, in violation of 97.205(e), will be documented and reported to the FCC. It's simple: Be courteous to other operators by using Color Code Free and you won't have a problem. But if you use a mode that allows you to override other operator's use of the repeater then you will permanently loose all operating privileges on the repeater.

Private Calls

Stations making Private Calls are asked to restrict private calls to time-slot 1. Private Calls, whether initiated while on a talk-group, or programmed by setting the TX Contact to a private call contact, can be carried out on time-slot 1. If you do not use a pre-programmed channel for a private call, please make sure that you are on a channel that specfies time-slot 1 prior to initiating a private call. If you are on a time-slot 2 channel when you receive a private call, please, at your earliest convenience, coordinate a pause and switch to a time-slot 1 channel prior to resuming a private call.
