[time-nuts] Heathkit GC 1000 Most Accurate Question

I own a Heathkit GC 1000 Most Accurate Clock. It's in terrific shape but not used for many years. It has stopped locking up to WWV and sometimes freezes up. Can any of our "nuts" repair it? Anyone want to buy it? Bill, w1...@aol.com ___ time-nuts

Re: [time-nuts] unidentified HF time pips

Hi Graham, I am listening to one of those "time pips" on 30m right now. (1714 utc 02/05/2018). Frequency is 10.105. The best I can tell with my calibrated ears and eyes, it appears to be in sync with WWV. Signal strength is about a s6-7. I also heard this on Saturday 02/03/2018 about the same

As previously mentioned, those frequencies are regular centres of activity for some of the Amateur digital modes; they are all within Amateur Radio allocations. As for Horsefly, I shall wait to see if anyone can correctly identify it! ;) Jason G7RUX On Mon, 5 Feb 2018 at 17:48, Ulrich Rohde via

Hi, Bill. I have three GC-1000s, one unbuilt and two built. Both of the built radios have stopped showing a time display. I haven't had a chance to figure out what happened to them. I live very close to Fort Collins, CO. I experience power failures fairly often and when my clocks were

I just realized there is also a 100 Hz decoder also u402. Both use the typical open air 1 turn pots. They get cranky with age. Regards Paul. On Mon, Feb 5, 2018 at 2:48 PM, Brooke Clarke wrote: > Hi: Bill > > Mine needed pretty much all the electrolytic caps replaced. >

oops, sorry for the misfire. > I couldn't figure out how to get to the insides to take a peek > without damaging it. For $99 I would take the risk to damage it... Or find someone with x-ray gear and have a peak inside. Or take it with you on your next plane flight and grab a photo of the TSA

Bill I see the manual is online for the GC1000. The 1KHZ tone decoder may be suspect in that its drifted off frequency. Its a little ne-567 chip with a pot. ne 567s were never all that great... Regards Paul On Mon, Feb 5, 2018 at 12:39 PM, Dave Daniel wrote: > Hi, Bill. > > I
