The possible reason is that the oven thermal gain isn't all that great (AFAIK), so you go to fair amount of trouble for marginal benefits. You will probably have to use a very long time constant which will sort of rule out a simple analog integrator, forcing a PID digital controller. If you're good with a PIC, it might not be too hard. I'm an analog guy; I don't speak PIC. :-) Rick Karlquist N6RK > > Thanks, > Ed > >> Date: Sat, 19 Jul 2008 17:33:07 -0400 >> From: wje <[EMAIL PROTECTED]> >> Subject: Re: [time-nuts] Double ovened 10811-60158 on ebay >> To: Discussion of precise time and frequency measurement >> <[email protected]> >> Message-ID: <[EMAIL PROTECTED]> >> Content-Type: text/plain; charset="ISO-8859-1" >> >> I got one without the outer cover, which isn't quite as useful.
