    Norm N6JV’s Tube of the Month

    The 2024 DX Marathon results were posted, and the MLDXCC placed 4th World in the Small Club category!

    Some interesting websites gleaned from IDXC presentations.

    Gary N6AO is taking a break from the Antenna of the Month. Stay tuned.

    And with the dissolution of the SCDXC, no more Deleted Country of the Month, unless someone would like to step up and continue them.

    Another Editor’s Note – Club History

    I am still hoping someone has some history about the first 5 or 6 years of the MLDXCC locked away someplace – please let me know if you do. If it is memories, I’m quite happy to interview you and take notes.

    I’m also still hoping someone knows anything about John Fogg, K6AO. I have so far learned that he edited the NCDXC newsletter in 1965 (source: NCDXC SK list), he built a 2 meter “pip squeak” transmitter from a design in QST in 1972 (Palo Alto ARA news), he lived in Pine Grove as early as 1976 (ditto), and in 1949 he lived in Alhambra not far from where I grew up (Callbook). And, for a brief moment I was excited to see a Wikipedia article, but it’s likely that our John Fogg was not the mayor of Pensacola FL from 1994 to 2009 (Wikipedia). Hihi. – Jeff WK6I

  • The New Nugget

    You’ll notice that The Nugget is no longer published as an Adobe PDF file. It’s now being produced in a blog format. This is for a couple of reasons:

    • Nobody really knows what goes in the depths of search engines on the Internet, but it is generally believed that content posted as normal website content (using Hypertext Markup Language, aka HTML) show up higher in search results than PDF content. This helps us attract new members better.
    • PDF files are not easy to read on small devices like phones and small tablets. Modern web pages know how to adapt to the size of the device – they call this “responsive” – making it easier for our members to enjoy the content on any device.

    Also, you’ll see that some of the major content and news is getting published right away – items like the Tube of the Month – rather than waiting for a monthly Nugget cycle. This is done to get the info to you in a more timely manner, and frankly it’s easier for your editor to spread the work out over the course of a month.

    Since it’s now in a blog format, you can access The Nugget and related news and features using an “RSS Reader” application such as Feedly, which runs as a web app in your browser, as well as iOS and Android. Copy this link:

    RSS Feed

    …on the Nuggets page to add The Nugget to Feedly. (It works here too.)

    While you are setting up Feedly, you might also want to add some other ham radio related blogs, like:

    Do you have any other favorite radio blogs? Let us know in the comments!

    If you are someone who prefers to print The Nugget, I’ve briefly tested it and things seem to print fairly reasonably. But if you have issues printing do let me know.

  • Interesting Websites from IDXC

    Here’s a few websites that I gleaned from DX Academy, Contest Academy, and Saturday presentations at the IDXC last weekend. Did I miss any? Add them in the comments! – Jeff WK6I

    Our own N6TV “TV Bob” presented “Station Automation Techniques & Recommendations” in the Contest Academy.

    Mark K6UFO explained “How to have fun contesting in FT Modes”.

    I’m sure you all are aware of this website, but I was not SolarHam.com, by VE3EN.

    Another thing I didn’t know about? ClubLog live streams. And these DXpedition listings. I need to get with the program…

    John NN6U presented “Contesting while activating POTA” (Parks On The Air). My takeaway is that, if you happen to be in a POTA park (like we often are during CQP for example), you can increase your visibility by operating as a POTA Activator. In particular, register your future activation on the POTA website, and when you go on the air you will get spotted there by POTA Hunters (and skimmers for CW/digital). This is not considered self-spotting. John said this presentation was basically the same as this one he made at the March 2024 NCCC meeting.

    There were also presentations by Chris N6WM on Remote SO2R and 2BSIQ, and Hank W6SX on Having Fun Contesting.

    A couple of websites from Bill K8TE’s “Tools for Propagation Prediction”. Here are some “Free DX Cluster Clients for Windows“. And Martti Laine’s book “Where Do We Go Next?” is available here to read for free.

    During the Contest Forum on Saturday, an attendee pleaded with the panel to explain all the acronyms and terms they were throwing around. Other attendees provided a glossary posted on the Contest University website, and another from the ARRL.

    Also on Saturday, AA7JV gave an interesting presentation on “Better Low Band Reception for DXpeditions“.

  • Tube of the Month – April 2025

    by Norm Wilson N6JV – Visit the museum at N6JV.com

    R3 – RECTOBULB

    In the July, 1927 issue of QST magazine, an advertisement was published featuring the “6EX Rectifier” by a company named the National Radio Tube Company of San Francisco, CA. The call 6EX was held by a Garrett Lewis. Rectifiers like the 280 and the 281 had become available by 1927 for receivers and low power transmitters, but no rectifiers that would handle the voltage and current required to power the larger transmitting tubes hams were wishing to use.  Arc rectifiers could be used but, they weren’t practical for most hams.  It was unusual to see a tube named alter a ham.  Hams would be assigned prefixes sometime in 1928.

    The 6EX was later designated the R-3 and started life as a high vacuum type, but the final product was mercury vapor with an indirectly heated cathode.  The maximum plate voltage was 7500 peak inverse volts at 250 ma.  The filament ran on 10 volts at 1.7 amps.  The tube had a standard UX base and a threaded stud out the top for the plate connection.

    I don’t know how well the tubes were selling, but Lewis had a ham friend in Southern California who wanted to replace the ARC rectifier he had sold him and build a new power supply. The friend was Don Wallace, 6AM, and he wanted to go big.  Lewis had also sold Wallace a re-built F328A which was a water cooled, 5 KW triode. 

    Don didn’t like QRP.  Don bought six 3 KVA pole pigs that were 220 volts in and 6000 volts out from the power company and mounted them in a rack with six of the new R-3 rectifiers.  The new power supply would be wired for six phase operation.  The schematic and rack photo are copied from QST magazine of February, 1928, where Don and Robert Kruse of the QST staff, wrote a 9-page description of the final power supply.  Six phase rectification results in an output ripple of six times the input ripple frequency.  In 1928, 360 Hz was considered a good CW note and adding a filter condenser would be very expensive.  The R-3 may have never been a commonly used tube as in a few years, the RCA 866 went into production and the R-3 became only a collectable.  Before WWII, Lewis moved to Silicon Valley where Lewis Electronics was formed and participated in tube production for the war effort.  In 1949 Lewis and Kaufman was organized and operated into 1956.  In about 1962, I bought two 3 KVA pole pigs from PG&E for $3 per KVA.

    Respectfully Submitted,
    G. “Skip” Chraft, N6NFB

    Treasurer’s Report

    Sue K6SZQ reported that, given the low level of activity, she’s going to switch to quarterly reporting. Look for the first quarter report in the next issue of The Nugget.

    President’s Corner

    Hi MLDXCC’ers,

    Well, here I am as President of this club again.  I swore it would never happen but Steve, NC6R, termed out.  In an attempt to keep the club healthy, I made the suggestion that I’d take over as President and Steve will be VP… with one condition… Steve will keep running the meetings and I’ll continue to arrange the meetings and speakers.  So, nothing has really changed other than a “loophole” in the Bylaws that allows us to continue as we have over the past three years.

    I want to thank John Stanley, K4ERO, for a terrific presentation at last month’s meeting on the subject of Antipodal Focusing, meaning propagation from your QTH to the opposite side of the earth.  We did record the meeting and, hopefully, Jeff will find a way to post the link on the all-new MLDXCC website.

    I can’t thank Norm, N6JV, enough for what he has done for our website and newsletter.  Without Norm’s constant “nagging” for content, we would not have had a newsletter and website with the great content we have had over the years.  Alas, Norm has finally found someone to take over the website and Nugget.  We all thank Jeff, WK6I, for taking on the challenge of filling Norm’s big shoes.  Keep doing those great tube articles, Norm!

    We have some really good speakers lined up for the upcoming months.  Our May speaker will be Chuck, NA6XX, who will give a presentation on 6-meter DX’ing and propagation.  Chuck, who lives in San Jose, will be driving to Habanero Hots, in Lodi, to give us his presentation in person.  I also plan to stream this meeting.  The date is May 10th.

    A few others have agreed to do upcoming presentations.  Stu, K6TU, will give a talk on his K6TU.net HF propagation site   Craig, K9CT, will give us a presentation on his super contest station.  Gary, NA6O, has also offered to give another one of his very entertaining talks.  Other presentation for future months are in the works.

    Both Steve and I have resisted streaming our meetings in the past for various reasons.  We will be streaming more of our upcoming meetings.  I do hope we can get more of our members from outside the core area to attend.  Maybe even Will, from down south who often participates in our reflector conversation, will show us what he looks like!

    In our February meeting, I did a contesting and DX’ing quiz, which seemed to get rave reviews, so we may do another one of those in the upcoming months.  The February quiz, and the answers, are in this month’s nugget.

    Last, and certainly not least, several of our members participated in the CQ WPX SSB contest last weekend at WC6H’s contest station.  Besides Rich, the operators included Jeff (WK6I), Steve (NC6R), Gary (VA7RR), Tim (NU6S), and Barry (K6ST).  The team did a whopping 14,097,405 claimed score to support NCCC’s effort.

    For those headed to Visalia, travel safe and have a great time! – Bob W1RH
