Exec series used a "crystal element", and Mastr II series used a transistorized crystal oscillator module called an ICOM (no relationship to the Japanese company). Crystal elements held 0.0005% just fine, but could not make 0.0002%. ICOMs came in both levels of accuracy. When the Exec was used in a 0.0002% environment like GMRS they swapped the crystal element motherboard for one that held 0.0002% ICOMs. More info here: <http://www.repeater-builder.com/ge/mastrii/m2icoms.html> Mike WA6ILQ
