    Hi folks,

    Well this is the Hobbies section, and I suppose making radios is a craft - so I thought you might like to see a radio I've re-built :eusa_angel:

    It's heart is a 50 year old valve receiver by Lafayette and supplied by Trio.

    It's a 9 valve MW and SW receiver, with CW/SSB AM capabilities, Q-multiplier, and Bandspread tuning.

    I bought it originally for £5 off Ebay. It was in a terrrible rusty state, filthy inside, and the smoothing capacitor had blown. :shock:

    You can't buy twin capacitor smoothing filters anymore - so I undid the aluminium case, emptied out the fried contents and resealed it empty. Then I purchased a couple of 650v electrolytics from Maplin, and soldered them to the old capacitor tags - works wonderfully.

    I've re-wired it and fitted new valves. Re-aligned, it is now an excellent receiver. All the knobs are off an old transceiver, and look pretty good I reckon.

    The wooden case I made myself from an old bookcase. Just polished it with teak oil, and it looks quite classy compared to the metal box it was in originally ..

    So it's sitting in my lounge now, and I can listen to shortwave stations without all the digital buttons, scanners and memories you get on modern sets.

    Good for another 50 years I reckon .. :eusa_angel:

    Damn cool. :thup:

    I built a Heathkit short wave back in high school. Took me months.
    Sure wish I still had it.

    The company, then known as Heathkit Educational Systems, announced in 2011 that they were reentering the kit business after a 20 year hiatus. The company filed for bankruptcy and ceased all operations in 2012.

    Heathkit - Wikipedia, the free encyclopedia

    Man, that was a short walk in the park LOL.

    Yeah. Myself and two buddies built the same shortwave kit about the same time.
    A friend sent them to an electrician to test them, and said mine was the best job. :thup:

    Wish I still had those QSL cards. I think that's what they were called.

    My dad built a few of these...he used to be the president of the Amateur radio assoc in our county. Him and my mom were really into these for a long time! It was fun when i was little listening to them talk to people on it. Still remember my dad's call number (or whatever you call it)...WB8IBB. :)

    Nice. Looks grand! Have you tried it on SSB? There are now also computer programs that will send out what you type as CW...but you need a TNC for that. There are loads of TNC kits to make.

    Hubs and I are Extra Class Hams.

    Regards from Rosie

    Hello Caroljo .. :eusa_angel:

    Yes, it's an interesting hobby. From your dad's callsign, I would place his station approximately in the Michegan/Ohio area - about 3,800 miles from me .. :D
