Communicating With You

MDARC has numerous methods of communicating with our members and the ham community at large:

1. Monthly Club meetings
The Membership meeting is on the third Friday of most months, starting at 7:30 pm. We normally have a business meeting first (as short as possible), followed by a speaker. There are a few months where we do not meet. 
See our Club Meetings page for details.

2. Monthly newsletter, the Carrier
The Carrier is the official newsletter of the Mount Diablo Amateur Radio Club. It is published 11 months of the year (not in December), usually about 1 week before our Club meeting. 
See our Carrier Newsletter page for more information.

3. P.O. mailbox
Our P.O. mailbox receives all postal correspondence for the Club. The address is:
P.O. Box 23222
Pleasant Hill, CA 94523

Our Contact Us page maintains this address and shows a map of our meeting location.

4. Weekly Thursday night net
The MDARC Club Net meets each Thursday evening at 7:30 PM on our W6CX repeater system.
          2 meters, 220 MHz and 440 meters: 147.060 /+ (100PL); Linked to 224.780/441.325 /+ (100PL)

See our Nets on MDARC Systems page for this and other nets on our system.

5. Main Club Web Site
Since you’re seeing this page, you know about our Club web site. We have a great deal of information here. Please explore.

6. Pacificon Web Site
We have a second web site for information on the annual Pacificon convention, which we host. Please see that web site for details and attendance registration.

7. MDARC Facebook page
If you’re a Facebook user, be sure to subscribe to our page.

8. Email Forum Groups
The Club maintains 8 email forum groups for communication with our members and other interested people, the Board of Directors, some of our committees and the students and elmers in our training courses. The Board and Committee groups are restricted to those members only. But our main Club group is open to anyone interested in ham radio or  MDARC, Club member or not. We strongly encourage all members to join the main Club group, as it is our primary way to communicate with our membership between meetings and newsletters.

Also, be sure to review our Guidelines, which describe some do's and don'ts to make using our forums the best experience possible.

There are two ways to join:
A.) Via the Web Site:
* Go to the group web page:
* Click the button: "Apply For Membership in This Group
* Fill in the email address you want us to use for our correspondence
If you belong to other groups, you may want to use the same email address as you use for those.
* Respond to the confirmation email the system will send you.

B:) Via an Email:
* Send an email to
Be sure to send it from the email address you want us to use for our correspondence

After you’ve joined, there are a number of settings you can adjust in your account profile if you wish; for example, receiving a single daily digest of all emails sent that day, rather than an individual email for each. To adjust those settings, go to and log in. The first time you do this, you’ll need to set a password. For Help, go to

9. Electronic meetings via Zoom
The 2020 COVID-19 pandemic required that we cancel all in-person meetings for the duration of the emergency. In response, the Club began meeting electronically, using the Zoom system. Invitations to each publicly available meeting will be sent out via our email reflector, making it even more important that you join that email group.

If you have not yet installed the small Zoom app, please do so before the next meeting. Though not absolutely required to attend the meetings, it makes participation much easier.

Also, be sure to review our Zoom Meeting Guidelines, which describe some do's and don'ts to help our meetings run smoothly.

10. Club Email Address
Anyone, Club member or not, is welcome to send us an email commenting or asking a question on any ham radio-related topic. If we don’t know the answer, we’ll try to find someone who does.

11. Club Telephone Number 
(925) 288-1730
Like the above email address, anyone, Club member or not, is welcome to call us with a comment or to ask a question on any ham radio-related topic. If we don’t know the answer, we’ll try to find someone who does. 

12. QRZ
The Club has two call signs (W6CX and W6LGW) and maintains a QRZ page for each. These are primarily for helping the ham community at large find and communicate with us.

13. YouTube Channel
The MDARC YouTube channel is currently not very active, but it does exist. And more content may be added available in the future.

To access it, either click on the above link, or go to and search for “Media MDARC”.
