    I was cleaning out the shack today and I found an old kit without instructions. It looks like most of the parts are there, so I would like to build it.
    The board is marked 9/94 on the component side. On the solder side it is marked "Copyright 1991 WA3FIY, Lee Richey, 90-35 REV 1." It has an L shaped aluminum enclosure, a single jack, and a 9v battery cradle. The crystal is 3.579. The enclosure has two holes; one for the jack, and one for a potentiometer.

    Any ideas where I could get instructions for this thing?

    Thanks for the replies. This isn't a tube kit. Lemme figure out how to post pictures, and I'll get some up.

    The crystal frequency (3.579(545) MHz) is that of a TV "Color Burst" reference , so that definitely leaves out a (ham) transmitter of any kind, but is often used with the MM5369N, which is a dedicated divider (IC) chip to give very, very, VERY close to 60 Hz output. There is usually a small variable cap to "pull" the crystal to provide exactly 60 Hz output for a DC powered time base.output.
    Does your "kit" have provision for an 8 Pin DIP integrated circuit (the MM5369N?) The kit you have might be a time base. Obviously, a picture would (so to speak) be worth a thousand words, so please try to post when you can.

    I found the article about this radio.
    It is an 80m W1AW receiver.
    QST Feb 1993.

    Edited to add Radio Adventures used to sell a kit as well.

    If you want to post pictures, you can upload them to your post by clicking on the "Upload a File" button next to the "Post Reply" button. But I'm glad we figured out what the kit is, sounds like a neat project. Now your task is to put it together and then show pictures of the finished project here.
