Welcome to the Durham FM Association

The Durham FM Association is a group of friendly amateur radio operators interested in all aspects of amateur radio service. Members in Durham, Chapel Hill, Raleigh, and surrounding areas of North Carolina enjoy operating through VHF and UHF repeaters sponsored and maintained by the club.

Currently the club operates FM voice repeaters on 145.450-, 147.225+, 224.260-, 444.100+ and 444.450+ mhz (the plus and minus indicating standard offsets on the respective bands).

We normally meet on the 1st Tuesday of the month (see Calendar) with Dinner (optional) at 6:00pm and the business meeting and program at 7:00pm.  We are meeting at Bullock's BBQ, on 3330 Quebec Drive in Durham. [click for map] (For more info on each meeting, check the Calendar entry.)

Our club runs a great hamfest toward the end of May each year. The DurHamFest was held in the Little River Community Complex for the last few years and expect to be there again.  Dealers sell new and used equipment, books, and parts. "Tailgaters" also offer much used equipment. Besides the buying, selling, and trading, door prizes and fellowship with old and new friends make this a really fun event.

Oct 7 Program: Building & Improving the Mantis Mill Print E-mail

Jeff Crews will be talking about the Mantis Mill.

The Mantis 9.1 mill is a low-cost, open-source CNC mill fabricated from plywood that uses innovative  design and construction techniques to achieve high precision with simple tools. It was originally developed by a graduate student at MIT, and uses a standard Arduino micro-controller board and the GRBL Arduino firmware to interpret Gcode and drive standard stepper motors.

After building one for himself, Jeffrey Crews and other members at Durham Splatspace (a local maker space) revisited and improved the existing documentation for the Mantis and made further refinements to the design so that it can be used for other materials and techniques beyond PCB fabrication.

Jeff will explain the operation of the mill and its companion open-source software, give background on the challenges of making and using one, and also demonstrate its use. A bill of materials, links to instructions and supplies, and advice about suggested upgrades will be provided for anyone interested in making one.

The Classic Exchange (CX) phone section will be next Sunday
(9/14) and the CW section will be the following Sunday (9/21).  A great time to hear real boat anchors on the air and work them.  This is a low key competition, actually, it is an on-air celebration of these good old rigs.  Details are at the CX web site CLASSIC EXCHANGE - CX - SEPTEMBER 2014. (see www.classicexchange.org)

While you are there be sure to browse the CX Newsletter from the January 2014 CX to get the flavor of the CX and enjoy some of the experiences of participants, such as who had the unusual rigs, most noteworthy (chirpy?) signal and the story of a receiver recovery "How The Fat Lady Got Her Voice Back."

Hope you will join us in reliving those joyful days of boat anchors on the air.

September 2 Program: DFMA Members (what about them?) Print E-mail

Friday, 29 August 2014 09:05

Michael, KK4EIB will present.  He write:

This presentation presents a population study of the DFMA.  I make a few population comparisons with some of our neighboring amateur radio clubs in the Triangle Area (RARS and OCRA) and project where our neighboring amateurs live on various maps, where the geographic center of these groups are located, and try to extrapolate where things are growing and where they are retrenching.

That will segue into where I will give a very short presentation on some of the efforts I'll be concentrating upon during my tenure as your new King (I'm still trying to figure out how to operate the wooden mallet Skip handed to me...).
