Midwest Classic Radio Net

The Midwest Classic Radio Net has been conducted on 3885 kHz AM since 1987 as a salute to classic AM rigs and operation.    The net remains one of the most popular AM nets in the country and sometimes last for well over an hour.

Harry N9CQX took over the net after long-time NCS WA9ZTY became a silent key and instituted record-keeping to know how many stations participated.  Before long annual participation recognition certificates were issued to the top 10 stations who checked in most often.  

This year, covid-19 has kept many of us indoors when we might otherwise be at hamfests or elsewhere so the competiton was more intense than usual!   But by checking into the MCRN 46 out of 52 times in 2020, W9RAN came in at 7th place, and this year, the top 20 participants received attractive personalized mugs!

Thank you Harry, for the mug and for the great job you and the other NCS stations do in making the MCRN fun for all the rest of us!


     Among it's early products, the Multi Elmac Company of Oak Park MI made marine band radios and other products for boats, including the Sea-Deep DM-1 depth indicator, the Sea-Fume SF-1 vapor detector, and the BC-1 Duo-Charger for 6 and 12 volt batteries.   Thus it's not surprising that the marine radio-telephone would be given a "sea" name:   the Sea...  READ MORE

   The Sonar Radio Corp.  of Brooklyn NY is a well-known manufacturer of Ham, CB, and Marine Band radios over a period of several decades, and it's products were always well engineered and of good quality.    But despite several attempts, it's ham radio products never really managed to excite hams enough to plunk down their hard-earned cash.   The SRT series of t...  READ MORE

    In 1958, the Multi Elmac Company was riding high on the ham radio waves.   The company had seen an opportunity to provide feature rich but affordable transmitters and receivers to hams itching to "go mobile", which was all the craze.   Instead of sticking a converter in front of the car radio like many competitors did, Elmac produced full-blown receivers that tu...  READ MORE

Mystery Transmitter

where's the copper subchassis from?
Category: Vintage Ham Radio
 I didn't set out to buy this homebrew CW transmitter, it was included in an auction lot that I wanted so I had to take it to get the desired item.   But even though I always like to see good quality homebrew gear, this one is just a mystery.Most of the transmitter, including 6CL6 oscillator and buffer stages and a 6146 PA are built on a sub-chassis that is clearly part of a com...  READ MORE

The Vector VR-50

last gasp from Swan/Atlas founder Herb Johnson
Category: Vintage Ham Radio
 Most hams are aware that Herb Johnson W6QKI founded Swan in Benson Arizona to make single-band SSB transceivers and then moved his operation to Oceanside CA where Swan thrived throughout the 1960s.   Swan merged with Cubic Corporation in 1967, and Johnson managed Swan as its subsidiary until 1973. Johnson founded Atlas Radio in 1974, with the assistance of Southcom International fo...  READ MORE

   The Harvey-Wells Company was formed through a partnership between Clifford Harvey W1RF, and John Wells W1ZD in 1939.   Cliff Harvey had earlier founded Harvey Radio Labs in 1933, and prior to that, he was associated with the Hendricks and Harvey Company, another partnership. Producing police radios, transceivers, transmitters, and crystals. Their most popular product was the TBS-50 trans...  READ MORE

    I became aware of a few hams playing with a thing designed to receive digital TV in Europe on your laptop - a little plug-in dongle that used an RTL-2832 IC and sold for $20 or so.    Some clever fellows had determined that it could be put into "radio mode" in which it would generate an IQ stream over USB, and by writing to control registers in the tuner IC, it could...  READ MORE

    A while back I acquired a six channel HF transceiver made by the Radio Industries division of Hallicrafters, probably in the 1960s, called an SBT-20.    It is capable of 20 watts SSB or 5 watts AM (or CW with an optional board) in the range of 2-12 MHz and thus was probably aimed at commercial and light-duty military applications.   The radio could by ordered with fu...  READ MORE

    I'm always thinking about interesting combinations of equipment to try out on the air.   One day while rearranging the shack I was getting ready to connect my Globe Scout Deluxe back up with a Collins 51S-1 receiver when the LED (the energy-efficient version of the old light bulb) came on.When I first started playing with DVB-T dongles back in 2012 I wanted an upconverter so I ...  READ MORE

6AG7-6LG Novice Transmitter

Classic circuit with some modern twists
Category: Vintage Ham Radio
 There's a good chance that more homebrew ham transmitters have been built using a 6L6 than any other tube, and when combined with the superior performance of the 6AG7 oscillator, it's a hard combination to beat (click here for an explanation of the 6AG7's benefits)I'll be adding more info about this project soon, but one of my goals was to reproduce what was a budget-friendly...  READ MORE
