Above you can see what I picked up at the Vienna Wireless Society’s 2024 Winterfest Hamfest. <\/b><\/div>\n

<\/b><\/div>\n
— On the left in the blue box is an MXM Industries SuperRX\/TX 40 transceiver. It is a kit from a Texas company. Superhet receiver with IF at 455 kHz. Crystal controlled CW transmitter on 7040 kHz. The oscillator works, but so far no receive signals. I will have to troubleshoot. Does anyone have a schematic? <\/b><\/div>\n


— Behind the MXM there is a nice box marked “Diode Detector” I opened it up and there is just a solid state diode and a 50 ohm resistor to ground. Box may be useful. <\/b><\/p>\n

— I got a couple of books: “Weekend Projects” 1979 from ARRL, and “A History of QST — Volume 1 Amateur Radio Technology 1915 – 2013” 2013 from ARRL. <\/b><\/p>\n

— On top of the Weekend Projects book you see a “Crystal Holder” from Gross Radio of New York City. W1UJR has some good history on this company: https:\/\/w1ujr.com\/written-word\/gross-radio-company-circa-1931\/<\/a> This device seem to be intended to hold in place a raw piece of quartz! Cool. <\/b><\/p>\n

— To the right of the books there is a serious-looking VFO. One dollar! Deal! It is a CB VFO, but the markings say it puts out 5.44 to 5.99 MHz. So it should be useful. The dual speed dial is very nice. <\/b><\/p>\n

— Above the VFO is a nice step attenuator from the “Arrow Antenna” company of Loveland Colorado. <\/b><\/p>\n

— Further to the right are some Electric Radio and Antique Wireless Association magazines that Armand WA1UQO gave me. Really nice. The AWA mags have a very thoughtful piece (warts and all) on Jean Shepherd. And the ER pile has an article by Scott WA9WFA that mentions my work on the Mate for the Mighty Midget receiver. Thanks again Armand! <\/b><\/p>\n

— I also got some ADE6+ surface mount mixers. The price was right! <\/b><\/p>\n

Thanks to VWS for putting on this great hamfest! <\/b><\/p>\n","protected":false},"excerpt":{"rendered":"
