[time-nuts] AOL Email Issues

Tue Nov 4 12:12:34 EST 2014

 Yep - got a bounce notice today. Did not send anything I believe.

Why must this be so hard? Would there be some huge cost
involved in getting a more forgiving server setup that does not
throw out all but the most primitive text. The FMT-nuts is a good
example of something that works well and accepts photos and graphics.

I would post many circuits and other
time nuttery stuff but the server arrangement make it just too much trouble.

So I don't bother.? 

Best regards to all? john K6IQL

There's been a  fair number of papers from Hahvahd about bulb coating for 
masers.  Interestingly enough, here's a patent: 

http://www.google.com/patents/US3859119 

from 1972. 

I had to figure this out, but Yuri is referring to flourophosgene a.k.a. 
carbonyl flouride. 

If you'd like to read a really nice detailed paper on bulb coating for Rb 
cells, try this one out:

Is anyone else with an AOL email address still seeing problems? 

I'm receiving some, but not all, of my own posts to the  list, with the  
"bounce" count on my time-nuts subscription page going up  accordingly. 

It seems to have reset a couple of times recently but is now up to 4   
again, and the rate at which posts are missed seems to  be increasing. 

I've checked my settings and all seems ok so would be interested to know if  
 this is just me or whether there are still wider issues?

I got a nice old Varian R-20 rubidium frequency standard that would be 
nice to get working. 
To begin with, there is at least a problem with the voltage regulator 
circuit. 

Does anyone have a manual? I couldn't locate anything on the web. 

Regards, 
Adrian

Same here Nigel, 

However I seem to have gotten about 200+ emails about a Lucent GPSDO over the  
last couple of days so something is working, or the list simply got inundated  
with Lucent KS-24361 related emails. 

Bye, 
Said
