DRC Brandmeister Update

By Bill Rinker, W6OAV
Update of 02/26/2017

The DRC BrandMeister repeater has a new powerful Local Talk group.
The new Local Talk Group is 310804 which replaces the original Local Talk Group 2.
The new Talk Group allows connections to it by remote users who either use a DMR Hotspot or have access to a remote BrandMeister repeater.

Group 310804 is statically programmed on Time Slot 2 which means it is always on.
Therefore, local users monitoring this Talk Group will hear any incoming calls. Users without DMR radios can monitor this Talk Group by pointing their browsers to This link will show any calls that have occurred in the last 15 minutes.

In order to properly use the new repeater configuration, you must load the latest code plug
(W0TX_ BrandMeister_MD380_Issue 1.rdt) into your MD-380/390. This code plug is the 08-06-2016 version of the RMHAM code plug with the W0TX BrandMeister zone added.

Contact me at for a copy of this code plug.

Our next Denver Radio Club Meeting will be

A Special Training Class on Storm Spotting - with Certification,
on Wednesday, March, 15th, starting promptly at 6 pm.

National Weather Service Logo            Skywarn Logo

Presented by Scott Entrekin, Senior Forecaster
from the National Weather Service in Boulder, with 27 yrs. experience.

NOTE: There will be NO Elemer Session nor Technical Committee Meeting in March.
The class starts at 6 p.m., in the larger Hearing Room #1.


At the March meeting, Scott will present a 2 ½ hour spotter training class in place of our regular meeting.

This class is not about "storm chasing".
It is about "storm spotting" - to make accurate observations from the field and relay them to the NWS office in seconds - without phones, e-mail, twitter, or texting.

A beginner orientation to Colorado weather will begin promptly at 6 p.m. with an “advanced” session starting at about the halfway point in the evening.
Successful completion of both sessions will entitle you to obtain an official spotter number, which can be used to call in vital information during real emergency conditions.

The class is also open to Radio Amateurs who are not members of the D.R.C.,
and Public Safety Personnel including: Police, Fire, Dispatchers and EOC personnel.
It is NOT open to the general public.

Please see the March issue of the Roundtable newsletter for more information.
This will be an important meeting - mark your calendar now!

We will be meeting at the Jefferson County Administration & Courts Bldg.
100 Jefferson County Parkway, Golden CO
Hearing Room  #2  #1
Coordinates: 39.727962N , -105.201500W
Full details are found in the "Club Meetings" link to the left.
