Amateur Radio Weekly – Issue 181
The antenna on Rocky Top
The University of Tennessee Amateur Radio club has a set of antennas nestled between the lights at the top of Neyland Stadium in Knoxville. The tower is so high, most of the 102,000+ fans wouldn’t ever notice it. With the lights on, it’s impossible to catch a glimpse.

The Record
Thank you for my signal report
Maybe this is a radical idea but for my own operation I will strive to start sending more accurate reports and help the other station truly know how they are being copied.

Building a feedline HF choke
The choke has a resistance of over 1000 ohms on most of the Amateur HF bands, and up to 5000 ohms in the middle bands.

Build an end fed match box
Connected to my end fed inverted L it shows decent SWR on 40 and 20m. My transceiver’s built-in ATU easily matched on both those bands.

It’s ‘Bug Roundup’ Weekend!

Ever since earning my ticket as a teenager back in '63, almost all of my on-air activity has been focused on CW ... I've always loved it.
Back when I first got on the air there were very few amateurs using keyers. Most used bugs and the remainder used hand keys. It was very easy to tune across the band and identify any of the locals just by the sound of their fist ... like snowflakes, no two were the same. The same went for most stations that were very active. DX or otherwise, one could usually tell who it was, long before the callsigns were sent.
So much has changed now with the almost exclusive use of electronic keyers and everyone pretty much sounds the same, which is rather unfortunate I think.
Once my interest in building vintage-style vacuum-tube transmitters evolved, my interest in bugs was reactivated and over the years I have purchased a few more.
I'll do everything I can to promote and encourage the use of CW and especially hand-generated CW. That's why I was excited, once again, to read a recent e-mail from W6SFM, posted to several lists that I read, announcing the Bug Roundup!
The Samuel F. Morse Amateur Radio Club, a Sacramento, California based CW enthusiast club wanted a special time to bring bug operators together on the air. In the same spirit as ARRL's Straight Key Night, participants are encouraged to make simple, conversational, “chewing-the-fat” QSOs using their bug type key. This is an opportunity to exercise, share and exhibit your personalized fist. This is NOT a contest.
However, there is a very easy and quick required signup form found at https://w6sfm.com/bug-roundup/.
Once you are registered for the event simply call "CQ BR" so folks know you are a Bug Roundup Participant. So lets grab that bug, clean those contacts, and let’er fly! We want to hear that “Banana Boat / Lake Erie Swing" or that commercial KPH/WCC quality fist.
Reserve the date! The event begins on Friday November 17th (00:00 UTC) and concludes Sunday Nov. 19th (23:59 UTC), 2017.
That's 4:00 PM Friday evening until 3:59 PM Pacific Time (LOCAL)
For more information, to register your station, and to help assist in spotting, potentially increasing QSOs, an On-line chat window link can be found near the bottom of Bug Roundup home page located at https://w6sfm.com/bug-roundup/ We hope to hear you all on the air! 73, W6SFM

Big shoes to fill!
The 2018 ARRL International Grid Chase follows on the heels of the successful Centennial operating event and the even more successful National Parks On The Air operating event.
The idea is work as many different Maindenhead grid squares as you can, on any band (expect for 60 Meters) using any mode. Contacts made through satellites will count; but contacts made through earthbound repeaters will not.
So how will all these contacts be kept track of? Through Logbook Of The World, of course! So it is imperative that you have an LOTW account as well as the station you are working. When you both upload your logs to LOTW; and you get a match, you get credit for a valid QSO for the ARRL IGC.
While total cumulative results will be posted at the end of the year, the clock will "reset" so to speak, at the beginning of each month. So each month of 2018 will be like a new operating event; or competition. (I hate to use the word "contest", as we all know that contests are forbidden on the WARC bands.)
Should you not know your Maidenhead Grid Square locator, it's easy to find out. You can either look yourself up on QRZ.com, or go to http://www.levinecentral.com/ham/grid_square.php. What's interesting about these two methods is that you might get different results. QRZ tells me that my grid square is FN20to and Levine Central tells me that it's FN20so. No matter ...... for the purposes of the ARRL IGC, you'll only need the first four places. In addition, exchanging the grid square during the QSO is not required. LOTW will keep track of that. I suppose that for those who will go out and activate rare grids, there will be some provision made for identifying what grid square was operated from when uploading contacts into LOTW.
Will this be as successful as the last two events? That remains to be seen. The Centennial Event was huge success and NPOTA was a monster success. In any event, kudos to the ARRL for continuing to come up with ideas to keep Amateur Radio life a little on the spicier side.
