I bought a broken clock on eBay. It wasn't even right twice a day. The Heathkit GC-1000 is another one of those items on my perpetual wishlist, so when the opportunity came to purchase one cheap on ebay in nonfunctional state, I jumped at it. The actual problem may have been due to a previously failed recapping (or a failure during the original build; I don't know the history) that damaged the reset line to the microcontroller. In this video I tear down the clock, get it up and running, and then fume about how once I moved it to its final display location in my office, it won't sync anymore. I also evaluate several antennas, including my own random wire antenna, a youloop antenna, and an MLA-30+ megaloop antenna. For more electronics projects, see smbaker.com
