delara newsDelaware Amateur Radio Association, Delaware OH VOL 37 NUMBER 3
Some comments after the competitionI had a lot of distractions and put in just a little over 5 hours. I don’t think any exciting DX was found. Seemed like today was subdued compared to Friday and yesterday. Lots of US callers but I don’t know if they were getting many takers. I know I was not. Can’t say it was the most fun contest I’ve done recently. Low power and low, small antennas are not great for a DX contest during the Sun’s sleepy period.One guy sent ’T’ for his power; I had to question him, I didn’t know what to make of that. He sent it again so into the log he went. I heard him pretty well for him transmitting 0 watts.

I was running 1000 watts on a loop antenna. At the beginning I thought WOW i'm going to average 70 or more an hour. Well as the contest continued of course that average began to drop. By Sunday afternoon I could S&P for an hour and only come up with a couple of stations that I hadn't worked. I was running two clusters, one from an external source and my own CW Skimmer Server. I think Larry was the only one from the club that also used it. When I called CQ I got no answers. I believe there were only 463 DX stations in the contest HI HI. All in all I had a great time.

They are saying that is was PR ops protesting the slow progress in restoring power after last summer’s hurricanes. If that is true, it went over my head. I don’t think about politics in middle of a contests.73, Joe, AA8TA ARRLDXCW Summary Sheet Start Date : 2018-02-17 CallSign Used : N9AUG Operator(s) : N9AUGOperator Category : SINGLE-OPAssisted Category : ASSISTED Band : ALL Power : LOW Mode : CW D ARRL Section : OH Club/Team : Delara Contest Team Software : N1MM Logger+ 1.0.7013.0 Band QSOs Pts Cty Pt/Q 1.8 21 63 15 3.0 3.5 30 90 23 3.0 7 69 207 50 3.0 14 282 846 74 3.0 21 37 111 27 3.0 Total 439 1317 189 3.0 Score : 248,913 : I really need to get my G5RV back up..

Many 'Professors Emeritii' will be returning this year to present, and one new session that caught my eye is "Utilizing Digital Modes FT8 and MSK144 for Competitive Advantage in VHF Contests" to be presented by W5ZN. Contest University will be held May 17, 2018, from 7:00am to 5:00pm, at the Crowne Plaza Hotel in Dayton, Ohio.A number of ham radio related interest groups previously hosted on Yahoo are moving or have moved to other services. If you can't find your favorite group, or notice that the activity seems less than you recall, check some of the other popular services such as Groups.IO, Google Groups, or even more traditional email reflectors like Contesting.com. For example, the support group for N1MM Logger+ started moving to Groups.IO on February 27.If you are using N1MM Logger+ in one of the upcoming RTTY Contests, make sure you're using version 1.0.7099 or later. An issue was fixed recently that may affect serial number incrementing.Dick, W7WKR, suggests that Rudy, N6LF's website be referenced for radial systems for vertical antennas. "He presents a six chapter study of vertical antenna designs with a strong focus on MF and LF (630 and 2200 meter bands.)"The wireless transfer of power is currently in vogue for powering or charging items that vary in size from cellular telephones to electric cars. At least one company has obtained temporary authorization to use radio spectrum to test its technology, and Amateurs should be suitably wary of any technology that has the potential to put thousands of watts of RF near or on the ham bands. There are other technologies that are also being pursued in the quest to eliminate the charging cable such as this one by Disney Research where the test setup is akin to placing a medium-wave loop antenna inside of a Faraday cage containing the devices to be charged. And then using around 2 kW of RF with radiator currents up to 140 Amperes.Dave, NK7Z, has added a second chapter on finding and identifying RFI sources using SDRs to his website: "RFI Site Survey - Part II, Interpretation." Dave discusses his setup, and provides real-world examples of certain types of signals that can be found, including over-the-horizon RADAR, switching power supplies, etc. (Jim, K9YC, via RFI mailing list)Faraday cages block electric fields, and are considered a good way to reduce the thread of electronic eavesdropping. But they don't shield against magnetic fields and in a recent paper researchers describe how an adversary could use regular computer hardware and special software inside a Faraday cage to transmit information via magnetic fields to a receiver located outside the cage.
