Boy Scout Radio Merit Badge
Lance, KC2MTO has been assisting and observing the DVRA Scout Radio Merit Badge program. BCRC is interested in a similar program, and Lance has volunteered to give us some insight into this worthwhile program. Be sure to come and hear Lance enlighten us about what others are doing and how we can participate.
This feature has been expanded and can now be found on page 4 of this Newsletter
It stands for Digital Mobile Radio. The digital revolution has now coming to amateur radio. Like Icom’s D-STAR and Yaesu’s System Fusion which both use digital technology but are not compatible with each other and are, in fact, proprietary formats unique to each developer so only their own radios are compatible.
On the other hand DMR was developed by the European Telecommunications Standards Institute and is a form of communication widely used in Europe and is compatible with any radio that implements the format. There are about 10 manufacturers of DMR compatible radios including Vertex Standard, Baofeng and Kenwood. In the amateur world there are about 1400 repeaters and 16,000 users of DMR.
DMR has several modes of operation one of which supports one to one, repeater and linked repeater operation. The linked repeaters are connected via the Internet which is becoming more and more necessary in this world similar to the Echo-Link and IRLP modes. Another mode of DMR uses a 12.5 kHz bandwidth and is supported by the two main amateur branches known as MOTOTRBO and Hytera DMR networks.
The traditional FM mode has the ability to hear signals that become noisy the farther away from the repeater you are but digital modes are different in that they have a threshold effect either you can hear perfectly well or not at all. These radios can be programmed to access various digital repeaters in a fashion that is similar to the common FM radio.
Operating DMR is similar to using the FM repeater. Like FM linked repeater networks, using wide area digital repeaters can tie up repeaters over a large geographic area. It also has features similar to CTCSS tones to limit users to listening only to their local group. This feature is called a Talk Group. While several talk groups can use a single repeater, other groups cannot access the repeater and will be blocked out if you monopolize the repeater. While technically advanced in understanding the inner workings of DMR, be aware that the digital revolution is coming.
For more information on DMR, see the October issue of QST, page 30; “Introduction to DMR” by John, W2XAB, from which this summary is taken.

Winter Field Day
This was the second year of participation by BCRC in WFD. It was FUN!! And cold. Well, OK – it was cold putting up the antennas; the operating was quite comfortable in the Tabernacle EOC. Thanks once more to Corky and Tabernacle for the use of the facilities. Participants were K2QPN, AK2S, NB2S, WA2RHJ, KC2MTO, WB2YZS, AC2JL and K2SQS. KB2CRN, KD2GDU, and WB2ALQ also dropped in. We missed the CW expertise of KC2TA (SK) this year. An unexpected benefit (?) is that we discovered the 80 meter OCF dipole did not work. That needs to be corrected before the June Field Day. All in all, an enjoyable weekend. Attached to this newsletter are a few photos from WFD 2016.
Happy Birthday to Jack N2VW, AC2JL Erin, WB2YZS Ron, NB2S Stan, and AK2S Don! And feel better soon goes out to N2CE Charlie, W2MAT Matt. Deepest sympathy to Maria N2CIS and Jack N2VW on the loss of Maria’s daughter, Dru.
Upcoming BCRC Events
Spring Fling Brunch
The brunch be held Saturday, March 19, at the Diamond Diner on Rte 38 in Hainesport. Start time is 9:30AM. This has proved to be a popular family event in the past, so bring your family and enjoy the hot coffee, bacon and eggs and all the other menu offerings. February and March are usually slow activity wise for BCRC so this social event gives us the chance to get together. No club business – just enjoy some good times with your ham buddies.

From the Editors
Happy Valentine’s Day to
all. We had a wonderful 2 weeks in

Blizzard. While we did get a lot of snow, we were fortunate that the gloom and doom of the forecasters once again did not happen. Massive power outages did not occur. But it could have. Local ARES and CERT teams were ready if the worst happened. Are you a member of ARES? CERT? RACES? They could all use more help. Recent changes in leadership in SNJ appear to be rejuvenating these teams. Why not consider joining?
