Don't you guys have anything better to do than nit pick over a
negligible warm up drift. I don't think that you will be planning to
do any ARRL Frequency Measurement Tests, within the first 10 minutes
of your K3 turn on !
I have bought several 10 MHz DOUBLE Oven Controlled Crystal
Oscillators, from off shore surplus dealers. They are reselling
surplus American or Russian built, high quality devices. Warm up
drift time to within < 10 cycles (Hz), has been less than 10minutes,
usually about 5. Some are spec'd of stabilities of 10 to -11th.
With these quality OCXOs, I have not found it necessary to use a Ruby
or GPSD oscillators to provide at least digital communication
required stabilities, even when used to stabilize 10 GHz xvrtr
L.O.s. The power savings, by using this type of device, is
especially valuable in field operations. I even have mounted one on
the inside of the blank back panel of my K3/10.
For supplying other devices with your now stable 10 MHz, DEMI has
nice four way 10 MHz signal splitters that even have LP filtering on
each output.
