[time-nuts] Precision Oscillator Parts FS
Fellow time-nutters, I have the following precision frequency parts for sale. Quantity (4) NOS 3.000.000 MHz Crystals. They are clear glass hermetically sealed in HC-6 holders and individually serial numbered. The were manufactured by Midland with a 51-67 production date. They were originally made for Hallicrafters military frequency standards. I have no other info as to oven temperature but I believe it is 85C as that what they typically used in other designs. I will sell them for USD$15 each postpaid in the USA. I will sell overseas for additional postage. I want to be paid by either USPO money order or personal check. Quantity (4) 10.00 MHz Crystal Oscillators. Made by EG&G. Model T 424, P/N 1DN14-CV90-2201-1. Made between 90-40 and 90-50. RFE. They are 2 X 2 inches square and ½ in thick with two 6-32 mounting studs on the bottom and also have 5 pins 1/4 inch long coming out the bottom. On one side the have a multi-turn piston capacitor. I do not know if they are temperature compensated or not but suspect they are. They run on 12 volts but do not have EFC, but I will include an article by a California Ham Radio operator who added that function as there is an extra available pin. I ran them all for about a month and set them to less than .1Hz error compared to my HP 5370B. I have not re-tested them since I moved to a better standard. These are far superior from what you would get from Mouser or other suppliers. Guaranteed to be settable at 10 MHz to less than 100 milli-Hz error. USD$ 30 post paid in USA. Additional for overseas. Same payment terms as the crystals. Please contact me off list if interested.

Sorry this is so vague. Is this true of the current beta, with heather.exe dated June 2, 2010 at 1:41 PM? There was a bug in the earlier April beta release that could cause it to run out of stack space under certain conditions. This could also contribute to the perception of out-of-control CPU usage. I updated the .exe in early June as soon as I found the bug, but at the time I was expecting a new source dump from Mark, so I didn't bother bumping the version number in the install script.

You can store the command line options (one per line, with the "/" in column 1) in the file HEATHER.CFG Type '?' and scroll down to the bottom of the help window to find where to put the file. Heather will read the .CFG file on startup. You and also store keyboard commands in a .SCR file which can be read either from the command line (/r command) or keyboard (r command). Script files can be nested 5 deep. Again, you put one keyboard command per line, with the first keystroke in column 1. Not sure why your unit shuts down after a couple of weeks... I have had one running for several months. There is a /TW command to put in waits. It will cut down your CPU usage quite a bit. Try /TW or /TW=## (where ## is typically 10 to 50) ___ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
