The Mighty Elmac Net continues

Wednesday is Elmac Night!

 

NEW NET CONTROL:   Rex WA6GYC from Troy MI picked up the Elmac Net on Febr. 27 and did a Fine Business job!   Hopefully he will be willing to continue in this role, as the lack of a primary net control and difficult propagation at this point in the solar cycle have made it challenging in past weeks.   Please turn your radio on - Wednesday is Elmac Night!  (Execept for the first Wed. of the month when it's CCA AM Net night).   And as usual, the Elmac net will go on vacation during the summer months of QRN and outdoor activities

Thanks Rex for stepping up!


Tonight (12/12/18) was the first Wednesday night after the untimely passing of N8ECR, the originator and net control of the Mighty Elmac Net and many have wondered what will happen to the net.  

The Net will go on, most likely with a net control in Michigan,  which would mean that most participants would come from the upper midwest - at least in normal times.    But the propagation we've had on 75 meters has been anything but normal, and tonight's net was run by long-time participant KA2J from near Rochester NY, who heard my barefoot AF-68 from northwest IL just fine - a 600 mile path.

It may take a  few week sto work out the new net procedure, but the net was important to Mike, that's why he was always diligent about finding a substitute if he couldn't be there.    He would want the net to go on, and so it shall.

With the changing propagation the pre-net activities have been starting  around 5PM central time on 3880 kHz with the official net at 6pm, or 0000Z.    While the net commemorates the "Mighty" Elmac rigs, any kind of gear is welcome, as long as it can put out an AM signal.   The Net has been a motivator for many to find, restore, and use Multi Elmac equipment, and a dozen or more Elmacs are typically heard when the band cooperates.

Wednesday is Elmac Night!   (except the first Wed. of each month when  the Collins AM net occurs instead).   If you're anywhere in the eastern half of the country,  give a listen on 3880 Wed. afternoon/early evenings and join us if possible.

The Mosley Commando II

Made in England and scarce even there
Category: Vintage Ham Radio
The Mosley CM-1 receiver is quite well known and not especially hard to find in the US even though it was the only radio produced by the company that has been well-known for antennas since 1939.   Or is it...?A full-page ad (advert for you on the other side of the pond) appeared in the RSGB Bulletin in 1963 for a nice looking and very capable SSB transmitter called the "Commando II&...  READ MORE

   I'm not ready to publish a description of exactly HOW it works, but 20 minutes effort with scissors and tape produced a prototype  Droplet Energy Generator that allows me to say for sure that IT WORKS!I duplicated the design shown in this video.   I wrapped a scrap of plastic in aluminum foil, then applied a strip of double-sided tape and to that attached a piece of PTFE thread-...  READ MORE

   When I was first licensed in the 1960s in Nebraska, two groups of hams were commonly heard on the air before those with jobs got off work - other teens like me and the disabled hams.   Some of my earliest Novice ham buddies were blind students at the Nebraska School for the Blind in Nebraska City, and there were many other visually-impaired hams, all of whom were exceptional operators, e...  READ MORE

   Old style mica capacitors were used in the pi-net matching sections of several vintage transmitters and the combination of age, heat, and high RF currents have made them likely failure items.   My Collins 32V-2 transmitter was to the point where it would not properly load to full power on 75 meters so something had to be done.   Mica capacitors are no longer made but fortunately new...  READ MORE

   I found myself wanting to convert various frequencies to other frequencies and wanted a cheap and easy solution, so I designed a simple "universal converter" using the NE-602 and a programmable oscillator from Epson.  I'd used the same combination in hundreds of "RANVerter" SDR Upconverter projects since my Dec. 2013 QST article and knew that while there were limitatio...  READ MORE

   It's always a challenge to hold PC boards during assemly and testing.  After purchasing a magnetic holder from Amazon  I realized I wanted more and could easily make as many as I wanted using inexpensive 3 mm hardware from eBay and some strong "fridge magnets".     All that's needed is to epoxy a standoff to the magnet - both tapped and threaded ...  READ MORE

   The Si5351 has been the biggest boon to homebrewers since the invention of the NE-602, especially now that quartz crystals are essentially obsolete.   But it's redundant to run the output of the 5351 through a johnson counter to develop the quadrature signals required for QSD/QSE SDR front-ends when there are three clock outputs available and the IC allows for phase offsets. &nb...  READ MORE

   It's pretty well accepted that the Pacemaker was not EF Johnson's finest effort.   In fact it was the first of several failed attempts by the King of the AM Transmitters to make the transition to SSB.    In the end, it was the rise of CB popularity that kept the company viable, along with its component business, while their ham business gradually faced away. &...  READ MORE
