About #1 below and the wire in the tree with radials off the ground... I was instantly reminded about Al Brogdon W1AB and his "Killer Antenna". He wrote about it in 2006 in his ARRL book "Low Profile Amateur Radio" (Chapter 8 and also pages 44-48) and in QST-July1999.
The "Killer Antenna" is something I've kept in mind ever since I bought the book seven years ago and is one of the reasons I bought a KX3, so I could try it out portable, something I cannot do on my postage-size lot. His portable results seemed impressive for an idea so simple; granted he was using a Kenwood TS-50. 73 Jerry KM3K -----Original Message----- From: Elecraft [mailto:[email protected]] On Behalf Of Jim Brown Sent: Tuesday, June 17, 2014 2:30 AM To: [email protected] Subject: Re: [Elecraft] Field Day tips On 6/16/2014 8:36 PM, Wayne Burdick wrote: > Here are our annual tips for getting the most out of your Elecraft rig at field day: I'll add some more tips about QRP on Field Day. I've done three QRP Field Days, and one of them our group won for 1A battery. The same group came in second when we tried 2A with a second station on SSB part time. 1) Use the most efficient antennas that you can. A wire thrown over a tree and a radial laying on the ground will get you on the air, but a resonant dipole high in those trees can easily be 3-6 dB better. And even more radials with that wire in the tree, and picking them up off the ground, will add a few dB to your signal. 2) Use the most efficient feedline that you can. If you're only putting out 5W, don't burn 2W in RG58. Use RG8, RG11, RG213. 3) Get your antennas as high as you can. On 80M, 10 ft more height for a dipole is worth about 1 dB, 5 ft for a 40M dipole. 4) Don't waste your time with SSB on FD. CW can be reasonably competitive QRP, and a lot of fun. SSB only be described as a struggle, and is definitely not fun. Been there, done that, burned the Tee shirt. :) The combination of #1, #2, and #3 can easily make a 10-15 dB difference in your signal. 13 dB is the difference between 5W and 100W. And here are some tips to help you avoid RF noise problems on Field Day. If you can't hear 'em, you can't work 'em. http://nccc.cc/pdf/CQP-RFI2013-2.pdf 73, Jim K9YC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected] ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
