The President's Comments

July starts the kickoff of the .  Details of this club contest can be found by clicking the logo above.  Whether you take this event as a serious challenge with the intent of coming out on top in one of the class categories or, if you are approaching it in a casual manner, what we want is for you to have fun.  Working DX may or may not be your passion but after all, we are a DX club and we want to do what we can to encourage you to get on the air and work DX!  Our DX Challenge provides many options for you to compete to receive an achievement award in a targeted class of operation.  Whether you prefer phone, CW or digital modes, or whether you run high power or low power or even QRP, we have a class in the challenge that will fit your operating preferences. So, shut off the TV, tell the dog he or she will have to wait for you to take them out, go into the shack and get those DX contacts in your log.  Above all else, have some fun on the air! .

Last Meeting
 15 August 2019  

  KB7AZ - Carl, attended this year and made a video of his meandering around the site.  He said it was a very good one with lots of vendors and the swap meet portion filled the whole infield of a race track.

AC2K - Alan, formally opened the meeting, and reminded us of the DX Challenge .

W7TUS - Mike, our Secretary/Treasurer reported that we are solvent and have 43 paid members

K7NN - Don  said that the program for next month was to be determined and asked for any input as to future presentations. After a short break Don introduced our guest speaker.

K7NN - Don  My DX-ploits this month have been up to 104 countries since July first in the SADXA DX  Member Challenge.  Now I have 195 country contacts.  I had a QSO with WD4CVK in the state of Georgia on 10 Meter He sent me a QSL card for this contact and on the card he mentioned that he had made a contact with me February 25, 1980 on 10 Meter SSB when he was stationed on Midway Island.  I looked in my card collection, low and behold I found the card he had sent me.  He was WD4CVK/KH4.  39 years later, nice he remembered me. 

W9FI - Jim My best DX QSO of the month was 5T5PA (in Mauritania) on 160m .  I worked him on Wednesday night and he confirmed that contact via LOTW on Thursday morning.   I've worked TO5M on Saint Pierre and Miquelon on 40m and 80m . That's a new one for me on both 80 and digital mode.  I also worked and confirmed HS0ZIV in Thailand on 40m , which was a new DX entity for me on 40. During the month I've worked a couple of dozen more DX stations who were calling CQ with nobody responding, but none of them were new ones.

  N7BDZ - Elaine told of attending the with K7RJ - Ron, saying they'd had a great time at the convention there in Salt Lake.

  K7RJ - Ron said "What she said."

W7DF - Tom was in the Salt Lake area and drove past the sign near the convention center where it said "Event Occuring", or similar, and was pretty disappointed that he didn't know that the ARRL Rocky Mountain Division Convention was being held at that time!  (Tom, I thought you knew EVERYTHING about the ARRL happenings.)

N6ITY - Dennis reported that he had been unhooked until receitly due to the monsoon activity and had not worked much.

AC2K - Alan said that he'd worked 40 on 40 CW for the and was installing a real tower since he'd have to major catastrophes with a push up tower and a hex beam.

W0PZD - Richard said he'd read where the sun spots weren't going to improve untill 2055 and figured he wasn't going to last that long so he's thinking of just packing it in. (No, Richard, you're not to forget the life saving !)

AA7FV - Darrell, besides his 20 meter phone activity, he's into  and reports: I have been looking at  WSPR signal reports from the UK on 20m. The WSPR transmitter transmits about 4 times an hour, with 2 watts.  In particular, in the last month Pete, 2E0PYB has given more than 200 reports on the  AA7FV 20m WSPR signal.

I've been swapping emails with Pete, and it out that he is a good friend of another club member, Ron K7RJ.

As part of this WSPR propagation study, I've been looking at reception reports from club member AE7YQ, who's only about 30 miles away, and receiving my signal fairly weakly, via ground wave.

On most days, the AA7FV peak signal hadn't varied by much more than about +/-3 dB, except on July 25th.  For about 15 minutes, there was a 30 dB enhancement in the signal.  I don't know why.  Aircraft reflection off a military plane circling above us? A mystery.

W7AQK - Dave reported that he'd worked 9 countries on 20 and 40 in the .

W7EXG - Bill said that there'd been some Sporatic -E on 10 Meters and he'd worked some on SSB in the early evening.

K6WSC - Bill reported he had worked 53 countries in the IARU contest in July.

W6XI - Jerry said that his towers were down and the coax coiled up and tied to the towers.  He wasn't going to have another of those lightening events that WF7D reported on.

KB7AZ - Carl reported working 30 countries in the .

To end the evening, the drawing prize was won by AA7FV - Darrel. Didn't he win last month?  I think the fix is in, huh, Darrel?

The winner of the July SADXA drawing and a $25 certificate good a at was AA7FV - Darrell.  

Yeah, we'd better check that drawing can.





SADXA Presents  
Presented by: 

K7DF - Tom


.Another great presentation related to the lesson given by Tom last month.  Tom has given this Grounding briefing to NASA and many others, and, who could use it any more than hams who live in areas where there are big lightning storms such as there are here in Arizona? We've all had experience with grounding and there are so many ideas out there.  You can prove that they work with the math analysis but do they work in real life?  We're all familiar with the various symbols to indicate , however, it's not simple matter to protect your electronic and electrical equipment from that nasty lightning. A smart person, with resources, might be wise to build his house or radio shack with protection in mind. You know, install a dozen or two, 8 foot ground rods with thumb size copper or flat braid between, around the perimeter of your house or shack and many more around the tower, etc.   When you move into a house that previously constructed, sometiems it's not as easy to design a good system of protection.  I hope yours doesn't look like this:

(And, no, it's not mine!) Of course, in addition to protecting your ham gear, a good ground is essential to a quiet HF receiver that can pull out those weak DX signals.   

Tom's presentation was very interesting and any ham who would like to have some ideas on how to protect his equipment should see it.  Thanks for telling us all all about it. If you missed this presentation, you missed a good one.  Very informative, to say the least.



Please send your DXploits to wd7f@wd7f.com. I makes it so much easier to get it straight for the record. Thanks to W89FI - Jim, he knows how to send email.



I have added a few additional links below as recommended.  I've received several new pictures of current members, but I'm still short a few as well as the bios.  I suppose it's not absolutely necessary that the page have your bio, privacy issues, you know.  However, after all, this IS an amateur radio organization and Hams like to talk and brag too. Hi, Hi.   I will be bringing my trusty camera to take pictures and I welcome any picture that you might prefer to replace the ones that I post.  Just e-mail a suitable picture to wd7f@wd7f.com

Thanks.  de WD7F - John

PS:  Any other amateur radio links you would like here just for fun?
