[KB6NU] ARRL extends Field Day rules wavers, sets class D and E power limit
KB6NU's Ham Radio Blog /////////////////////////////////////////// ARRL extends Field Day rules wavers, sets class D and E power limit Posted: 11 Feb 2021 08:01 AM PST http://feedproxy.google.com/~r/kb6nu...m_medium=email From the ARRL website The COVID-19 pandemic-modifiedÂ*ARRL Field DayÂ*rules from 2020 will continue this June with the addition of a power limit imposed on Class D (Home Stations) and Class E (Home Stations-Emergency Power) participants. The news from the ARRL Board’s Programs and Services Committee comes as many clubs and groups are starting preparations for Field Day in earnest. Field Day 2021 will take place June 26 – 27. “This early decision should alleviate any hesitancy that radio clubs and individual Field Day participants may have with their planning for the event,” said ARRL Contest Program Manager Paul Bourque, N1SFE. For Field Day 2021: Class D stations may workÂ*all otherÂ*Field Day stations, including other Class D stations, for points. This year, however, Class D and Class E stations will be limited to 150 W PEP output. AnÂ*aggregateÂ*club score will be published — just as it was done last year. The aggregate score will be a sum of all individual entries that attributed their score to that of a specific club. ARRL Field Day is one of the biggest events on the amateur radio calendar. Last summer, a record 10,213 entries were received. “With the greater flexibility afforded by the rules waivers, individuals and groups will still be able to participate in Field Day, while still staying within any public health recommendations and/or requirements,” Bourque said. The preferred method of submitting entries after Field Day is via the web applet. The ARRL Field Day rules include instructions on how to submit entries, which must be submitted or postmarked by Tuesday, July 27, 2021. TheÂ*ARRL Field DayÂ*web page contains for complete rules and entry forms, as well as any updated information as it becomes available. Join the ARRL Field DayÂ*Facebook page.

Here are three from the 1921, 1971, and 1996 issues..Dan Some Whys, and Speculation as to Some Possible Wherefores by M.B. West. Some interesting speculation about how to improve the transmitters of the day. Remember, this was 100 years ago. Quad vs Triband Yagi by Col. John Parrott, Jr., W4FRU. Clarence Moore, the inventor of the cubical quad, probably little realized when he and his associates were huddled of the reference books back in 1942 that the product of their efforts would receive such widespread acclaim and damnation as has been poured out upon the cubical quad antenna. The conclusion of the article, though, is: One can expect to achieve the same or better results with a two-element quad of proper dimensions that with a three- or four-element triband Yagi. A wide-space quad will perform substantially better that a close-spaced quad. Dollar-for-dollar, the quad appears to be a better investment than a Yagi. The question then, is, why are there still more Yagis than quads? DSP—An Intuitive Approach by David Hershberger, W9GR Digital signal processing (DSP) is, of course, all the rage now. Back in 1996, though, the technology was really just getting off the ground. Prices for DSP chis had dropped from around $200 to $5 to $20 ($8.50 to $34.00 in 2021 dollars). W9GR writes, This makes them ideal for low-cost amateur applications. Thanks to low-cost DSP chips, digital approaches.are now more than competitive with analog methods. What follows is a nice explanation of basic DSP techniques, without a lot of math. Intuitive indeed.
