[time-nuts] Rubidium Cells for Sale ?!

2019-05-05 Thread ed_palmer
I've seen lots of weird stuff on ebay, but I never thought I'd see this!

https://www.ebay.com/itm/123737315177

Anybody feeling lucky (or desperate!)?

I have no connection with the seller.

Re: [time-nuts] FTS 1050A Service Manual

2019-05-05 Thread Matthew D'Asaro
I doubt that cloning has much to do with it. Any cloner worth their salt 
wouldn't have any problems reverse engineering a PCB. The real problem is that 
it is expensive to produce and maintain service documentation and there doesn't 
seem to be market demand in this throw away culture.

Hi

Well, it this day and age of “clone anything” manufacturers, I doubt you ever 
will see
schematics again. Most outfits stopped sending them out decades ago.
