Interested members should contact our 4/9 SCCARA General Meeting president, Gregg KF6FNA. 4/14 Electronics Flea Market -- WE HOST! 4/16 SCCARA Board Meeting--(San Jose Red Cross, 7:30p, all are welcome) Flea Market We host the Electronics Flea Market April 14 General Meeting Day: Monday, April 9, 2018 SCCARA has the privilege of hosting the Electronics Flea Time: 7:30 PM Market at a new venue. Yes, the April 14th Flea Market will be Place: Kaiser Santa Clara, Hospital B-06 held at Fry's Sunnyvale, 1077 E. Arques Ave., Sunnyvale, just west Featuring: {to be announced} of Lawrence Expressway. The vendors will set up east of the building. It is imperative that SCCARA does a professional job conducting this flea market as Fry's management will be analyzing how it benefitted them... increased customer count, burnished community outreach image. This will determine if they will allow future flea markets on their premises. It is with your help that SCCARA will be known as the club that convinced Fry's that having future Electronics Flea Markets at their location is an asset to their operations. Do sign up and help the cause. Two hour shifts are available from 0500-0700, 0700-0900, 0900-1100 and 1100-1300 but you may, indeed are encouraged, to sign up for multiple shifts. If you have not participated before, now is your turn. Bring family and friends to share the fun. E-mail Lou at [email protected] with number in your party and shift preferences. Lou WA6QYS You can help convince Fry’s management that the flea market is a good thing. If there’s something you need or want to get at Fry's, the time to buy it is during the flea market! Spread the word! Also, for those who would like something a bit more nutritious than doughnuts at the flea market, keep in mind this Fry’s has a deli in the middle of the store. Personally I like their pastrami sandwiches. ( And remember, Fry’s has no fee for parking. 73, Gary WB6YRU Page 1 SVECS Breakfast The SCCARA-GRAM is published monthly by the SANTA CLARA COUNTY AMATEUR RADIO ASSOCIATION, PO Box 106, San Jose CA 95103-0106.

  • AN INTRODUCTION to BEACON DXING V1.1
    AN INTRODUCTION TO BEACON DXING: by Alan Gale, G4TMV Version 1.1 January 2020 There has been a growing interest in Beacon DXing, something which for a great many years was always viewed as a ‘minority’ interest, but thanks to organisations like the NDB List and clubs like the Longwave Club of America (LWCA) , this type of listening has now become a lot more widely enjoyed by many listeners around the world. Back in the 1990s I produced a publication called ‘ An Introduction to NDB DXing ’, which later evolved into a much larger e-book called ‘The Beacon Hunter’s Handbook’, and this was available from the former Beaconworld website, but due to various health problems, and the vast amount of time it took me to keep this up to date, it largely vanished from the Internet when I closed down the Beaconworld site back in May 2010. It was obvious that some sort of publication which would provide useful information to newcomers to the hobby was still required, but not wanting to get back into the situation of having to spend a lot of what little spare time I have in keeping it up to date for the same reasons as before, and because there are still copies of the old publications available from various websites, I thought a simpler and more easy to manage publication using some of the essential parts from the old book, plus a few new additions might be the easier option. I have used some of the older material to produce this publication, and given it a slightly different title to avoid any confusion with the former publications, some of which still
