Holiday Party, Dues, and January Meeting





Ascension Lutheran Church, 1220 West Magee Road

Grace Hall


OVARC Members and a Member’s Guest are invited to the annual OVARC Holiday Christmas Party at 3PM on Sunday December 15 at Grace Hall. As in past years, the event is a potluck party and to avoid duplication you can check the following signup genius to see what dishes are most needed. The club will provide the main dish.

Sign up here for the potluck


We will have a great raffle during the party with plenty of prizes so please take advantage of this members-only event. Please also consider bringing a non-perishable food item for the church’s food drive. 

There isn’t a sign-up genius for chefs but if you can arrive early to help setup the room and do some cooking, that would be excellent.


2020 DUES

Dues for 2020 are now being accepted. The good news is that we are able to keep the dues the same for another year. With rising expenses, it’s getting harder to keep our dues so low but please show your support for the club and pay your 2020 dues as soon as you can. As announced at the November OVARC meeting, members that pay their dues by December 31 will automatically be entered into a special raffle for a $100 DX Engineering Gift Card. If you’re going to renew your membership anyway, why not do it before December 31 and get into the raffle?

Arrangements are being made for a live presentation at the January OVARC meeting on January 17, 2020. As usual, we will hold our annual Election for Directors too.

All About APRS -- Automatic Packet Reporting System

Presented by

Marnee Dearman, KG7SIO


APRS stands for Automatic Packet Reporting System. It is a digital-mode packet-radio protocol. Basically this means that you transmit encoded data and it sounds like scratchy modem-noises.

APRS is often thought of that system where you can transmit your GPS coordinates and you'll show up on a map. While this is true, and often how APRS is used, there are many, many more possibilities. So many that it gave me an idea for an APRS software application, which took me down the rabbit hole of everything APRS and amateur packet radio.

I will cover everything I learned along the way of developing my own APRS software application, and how anyone, even non-programmers, can get involved in the project.


Marnee, KG7SIO, is a member of the OVARC board of directors, and the website manager.

DMR - Digital Mobile Radio

Presented by

Bob Molczan, KA7VPR

Digital Mobile Radio (DMR) has been available for use by Radio Amateurs for several years, although out of reach for many due to the high cost of equipment only available from the commercial radio market.  Within the last 3 years an influx of affordable DMR radios for the Amateur market has made DMR available to everyone at costs remarkably less that current market analog/digital equipment from leading HAM radio manufacturers.

DMR is a very efficient Digital Voice mode with High Quality Audio and Superior RF Signal propagation characteristics.  DMR repeaters are linked world wide, and the availability of two DMR networks, Motorola and Brandmeister offer options to both the Experimenter and the Casual operator.  DMR Repeater and Hot Spot building is available and adds to the fun and effectiveness of DMR.

However, DMR has been given a "Bad Reputation" as being "Hard or Impossible" to program when it comes to developing a profile or "Code Plug" for one's radio.  For this reason many have either given up on or shied away from DMR to seek ease of operation from other digital voice modes.  This misconception of DMR's "lack of user friendliness" makes it difficult for Multi-Mode repeater groups like OVARC to justify keeping the DMR mode active on our area repeaters.

My presentation will attempt to dispel all of the misconceptions about programming DMR radios, and provide a clear explanation of how to write a "Code Plug". Details pertaining to DMR terminology and different "Customer Programming Software" (CPS) will be provided, along with samples of code plugs and much more.

I personally have been using DMR for over 5 years now, and own both commercial and amateur DMR radio gear from companies like Motorola, Vertex, CSI, and Anytone.  Although I do not claim to be an expert on DMR, I believe that I can remove many of the obstacles that keep you from making DMR your "Go To" mode for Digital Voice communications.  Please join me at the next OVARC General Session club meeting in October.
