No, But I live in Rio Rancho and monitor the Sandoval County system a lot. It's pretty simple, actually, since all it is is a "poor man's voteing system". They Have several repeaters all around the county for both the Sheriff's and the Fire departments. All have different PL access, so depending on what repeater you need to access, they have different PL's on different channels, but it's still all the same input and output frequencies. For the Sheriffs you need to listen to 155.31 (also the NCIC channel of 151.235) and for Fire/EMS listen to 155.145. There is a fire repeater in La Cueva, so you should not have any issues picking that up. Now they will often go to the state fire simplex frequency of 154.31 when they go on scene, so unless you are close, you will be SOL.
