Has anyone used one of these crystal heaters to help cure the drift problems that some radios tend to have?
**NEW! 40° precision crystal heater
This precision crystal heater provides temperature compensation for crystals, usually found within crystal oscillators. The assembled circuit, which is built on AL2O3 ceramic substrate, should be mounted against the thermostat crystal using heat shrink tubing. The circuit heats the crystal to a temperature of 40.8° C with an accuracy of better than 0.1° C. This provides high frequency stability over the temperature range of -5 to +40° C. This crystal heater is a reasonable alternative to completely heated OCXO´s which values can not be reached.
Specifications
Adjustment tolerance 40,8° C +/- 1,5 °
Regulation accuracy better 0,1° C
Operating voltage 8...12 V use stabilize voltage
Inrush current ca. 80 mA
Dimensions mm 10,5 x 14,0 x 3,5**
Thanks,
