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 They were originally made for Hallicrafters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.
Regards,
Perrier
