Re: [time-nuts] HP 117/10509a
Yes. I would definitely be interested in information on your conversion. Like you I would prefer attempting a successful conversion as I don't have the knowledge to develop one myself. Thanks, Merchison On 2012-07-05 3:14 AM, Ron Ward wrote: Thanks Charles: I will consider your ideas as they seem to be excellent! I wonder if I could just make the whole unit run off of +24VDC or +12 VDC. I need to look at the schematics and see what would be the best way to proceed. I currently do not have an antenna for WWVB and need to get up and running before I do anything with it. If successful, would anyone want information on my conversion? I also have a fluke 207 that needs to be recapped.

I thought about doing that but I did not want to spend a lot of time experimenting fruitlessly. Thanks for the encouragement. Merchison On 2012-07-05 11:19 AM, Burt I.

Being young and foolish and thinking this is basically audio, I went to Radio Shack and got some N-Channel FETs and stuffed the FET's leads into the appropriate Nuvistor socket pins: Gate to Grid, Source to Cathode, and Drain to Plate. As I recall, I had to add a wee bit of capacitance to make it tune back down to 60 KC - back then I didn't know from kHz. I made a voltage divider inside the antenna's junction box to get the higher voltage down to what the FETs wanted. It ran fine for the remaining 8 to10 years that I used the RLF-1's. I forget where the antenna went, but it may still be in use somewhere. At least I hope so.

I would like to replace them with inexpensive FETs instead of buying the expensive Nunistors. Thanks for all help, Merchison Burt I.

Glad to know that it is not finalised as yet. When I read about this wrinkle, I was about to put my units up for sale. Merchison On 2012-07-05 1:54 PM, Bob Camp wrote: Hi Simple answer - they are still playing around with the signal format. It is totally unclear what the final format will really look like. Until they make up their minds there is only one safe bet - the clock on grandma's wall will still handle the wwvb format they use. Anything more complex than that is very much in the who knows category.
