The EME177 Crystal Heater has been specifically designed to suit the EME175 Oscillator Kit, to help stabilize frequency drift due to temperature. It can also be used on many other products that have a frequency reference crystal including Radio Transceivers, Receivers and other oscillators that use crystals. This Kit is also suitable for portable battery operation, and can be set for a temperature between +30 and +75 degrees C.
Unfortunately many of the older information links have now gone due to businesses being bought by other manufacturers. Much of the older knowledge has now been lost.

This picture shows how the Regulator and TC1047 is soldered to the board.
1/ With Rev-2.2 Kits after February 2024, the TC1047 has been replaced with a TMP236 temperature sensor.
2/ The original version 1 board was updated to a EME177-Rev2 in late 2017 and has minimal changes due to the trimpot being obsolete and better power supply stability for the TC1047 sensor.
