Yes, all avalanche beacons on the market today have to meet the standard frequency put into place by the European Telecommunications Standards Institute (ETSI) that standard is 457kHz in send and receive mode.
The TX 600 does not fall under this category, it transmits on 456.00kHz and is designed to be a secondary search tool for dogs and equipment, thus preventing a dog or a piece of equipment being found before any human 457kHz burials.
